[POLL] Audio Hiss Problem - AT&T Samsung Galaxy Note I717

The audio DSP used in our Note's is the Yamaha YDA-165. While this is one of Yamaha's first offerings in the low power audio codec chip market, it's not a very good one. Wolfson chips have generally been said to beat it hands down, and if you examine a comparison Anandtech did between it's possible sister chip (or a really close relative) and the iPad 2's Cirrus chip, you can see why.
It has been discussed that there is a slight hiss when listening to headphones during moments when nothing is being played (in-between songs, for example). I'm here to see if we can discover exactly why this is and maybe uncover some solutions. I've attached the PDF of the YDA-165's cut sheet to this post so everyone can skim through it.
I have noticed that there is a noise gate on chip, however, it's only for use with the speaker if you'll look at the block diagram.

Here is my DMESG if anyone wants to see it: http://pastebin.com/f4WnJC7j
When I get more time, I'll fill this post up with some more observations about the codec.
The HP amp is nearly maxed out, power-wise. According to DMESG, it's being supplied with 2.6V out of a possible max optimal range of 2.86V. I don't know how to determine the HP amps' dB output though (It's probably set at 0 by default). The attenuator for the HP amp may be locked to a specific range by Sammy, although it's capable of (-36dB)-(0dB), which I assume it is probably also set at by default. If we can get the HP amp increased to 3dB, we'd be able to get more power out of the amplifier, utilizing the digital signal gain in the DAC less. Analog amplification as opposed to digital amplification always results in cleaner audio.
The minimum headphone impedance for the codec is 12.8 ohms.
Comparing the amplifiers SNR to both Wolfson and Cirrus shows that it actually produces less noise than both of the aforementioned manufacturers. This leads me to believe it most likely is either a crappy DAC to blame or simply bad shielding.
Another thing to take note, the YDA-165 in our Notes does not have the same model number as the one found in the GS2, which is YMU823. With no documentation on the YMU823, there's no way to know how different or similar the components inside are to the YDA-165.

No worries - was slightly confused.
I have a pair of Bose QC2's, let me check the package.
EDIT: I can't find any reference to ohms in the manual or specs. But I did discover something interesting. On my headphones, there is a detachable audio cable with the "HI" and "LO" setting for "LEVEL". If I switch to "LO", obviously the volume decreases, but I also no longer hear a hiss. My guess is that the signal doesn't get amplified enough to hear the hiss. Anyway, which "Yes" option should I pick?

I did some Googling, and it appears Bose doesn't do a very good job of listing product specs ANYWHERE.
The detachable audio "cable" most likely contains an in-line resistor and actually increases the resistance of the line to well over 16 ohms. I think we're on to something here. Don't select anything in the poll since, well, we have no idea what ohm ratings there is with those Bose QC2s.

Subscribed....you might also post in the skyrocket and tmobile galaxy s2 they have the issue too

Obviously, I don't know much about the nitty gritty technical stuff, but it seems like additional resistance would effectively reduce or remove the hiss? Would this be similar to doing noise removal processing on an audio file?

It's in how an amplifier works, really. Electrical equipment is more efficient when it uses more power. When you increase the resistance, you're effectively increasing the amount of power it takes for the amp to drive your headphones.

I think introducing more resistance would probably work (I'll try it tonight), but would be nice to completely understand how this sound chip is used in this device and maybe someone can whip up an app to really control the amp so people do not need to be carrying around extra equipment! (run on sentence but I'm not gonna edit it!)

30ohm W3s here. Definite hiss. When it is playing system sounds, you can very clearly hear when the output is turned on and off. Quite annoying, but the rest of the phone is worth it. FWIW, just for comparison sake, I didn't have any noticeable hiss like this (that I remember) with the iphone 4.
This is probably the wrong thread, but does anyone know if the drivers are built in for a USB DAC? I could always use mine I guess, but haven't even looked into it yet.

It's beginning to seem like it's simply a lack of adequate shielding that's giving us this noise issue. It could also very well be the headphone amp too, but until we're able to manually control its output, there's no way to know for sure.
As far as the drivers go, I highly doubt Sammy included them in the stock rom. You'd have more luck on an AOSP build.

Found the inline attenuator and it works well but I have to turn the volume way high now. Hope I don't accidentally blast my ears if I forget to use the attenuator!

I've got a pair of SHURE SE110's that are rated at 27 Ohm and I definitely have a hiss. I've owned them for a good 4+ years and have never experienced a hiss on any sort of player until the Note. I've got some Thinksound Ms01's coming tomorrow that are rated at 16 Ohm. After I burn them in I will give them a listen and see if they hiss as well.

Interesting, however, without sensitivity specifications, the results would be moot. It appears ohms may be related, but I would need to completely throw driver sensitivity out of the equation.

Best stereo bluetooth headset with 3.5 mm jack?

Can somebody recommend a stereo bluetooth headset for the HD which has a 3.5 mm jack to use your own headphones?
Thx
I'm confused by this - Why would you need a 3.5mm jack if they're bluetooth??
I use the Motorola S9 bluetooth headset and it works perfectly - I also have iTech blueband ones, but not tried those as yet (no need to really)
I tried my sony wired phones last night watching a movie on it and they work perfectly as well (first time I tried the 3.5mm jack output)
I use the Sony DS980, and the sound is awesome. Its got a mic on it, as well as an OLED console display that lets you access your phone book, make calls, displays song title, etc.. but check it out on youtube.
I've got the Motorola S9 as well and can't recommend it.. the sound, the build quality, the features, battery life -- all pretty poor.

It's a simple explanation: I don't want to have to take it out of my pocket when I'm listening to music or taking a phone call and I want to use my own Sennheiser earphones.

STILL not with you on this dude - they're either wired OR bluetooth, certainly the way I interpret it (unless you mean a dongle of some description???)
Is there some kind of product out there that allows you to 'piggy back' into and use regular wired headphones into them or something??
I wouldn't dispute that the Sony's are way better than the motorola - I can't use earbud phones though [at all!] otherwise I'd love to give them a try - and yes, now you mention it the battery life really does suck too - I use mine only ever in the gym though so they're fine for a couple of hours at a time

I have tried both the SE HBH-DS205 (your bottom picture) and the Sony DRC-BT15 (your top picture). I think that the SE version has nice sound (good bass and highs, even without Audio Booster in stock Audio Manager), but it has no playback controls, so the phone willl need to come out of you pocket sometimes.
The Sony version has playback controls, but it is very thick and the sound was a bit "tinnier" to my ear.
With both of these units, I had issues with swistching between calls and music. Sometimes the switch back to music works, sometimes it doesn't and the music comes out through the handset speaker at full volume (much to the chagrin of NYC subway riders around me). I have read in these forums that disabling or adjusting the min/max BT bitpool can alleve these problems, but I like my bitpool high for the sound and am tooo lazy to fiddle around with min/max settings, sooo...
I just use Ultimate Ears Super.fi 4vi, a wired set with a very lightweight profile, a mic and (most importantly) the best sound (to my ears) out there for a 2-in-1 headset.

Then just get Blutooth headphones - like the motorola S9. You can take calls, listen to music, skip tracks etc. Most ones allow that.
The best
Sony Ericsson HBH-DS200, for me the best.
sk801, is it possible to use the Sony BT dongle to control the HD, while using your Superfi connected to the HD by the 3.5mm port (wired) for earbud sound?
Also, I assume your 4 vi control/mic is working on the HD? What controls does it have aside from call pickup/end?
perhaps stupid question, im looking for a stereo BT device and those sony ones look quite nice BUT do they work to skip tracks while you're playing music on the htc player and the pda has the screen off???
I have Motorola Pilot
MOTOROLA SOUND PILOT S705,
...Remote Control...Play, Pause, Volume And Track Control. Ability to take calls in mid music,3.5mm Headset Included... Or Use Your Own, Extended Range...Up To 330 ft., FM Radio, Wear Comfortably...Shirt Clip And Neck Strap Included, Caller ID And FM Station Display,Talk/Music Time...Up To 7hrs. Standby Time Up To 3 Days
I my case I am using it with my own Sony MDR-NX2 that comes with a convenient neck-strap, so I hang the bluetooth there, they are really comfortable, the sound is very good, you can lock the buttons, and you can find both things on ebay. I used to have and HTC advantage so it was very bulky to use it as phone, so these both products made my life easier, and now with my htc touch HD I am using them too, because I don't like the wires and the headset that comes with it. on the other hand you can use also the bluetooth with regular speakers if you own ones to streem and answer your calls from it.
the sony 980 doesn't work very well? both of you get the same results? i was thinking of buying that... if you could explain then it would be greatful thanks!
What do you guys thing about the new Sony HBH-IS800? You think they will be worth it? I mean will I be able to skip tracks with them?
Here a litte picture of the earphones:
Definitely thinking about buying them!
Ascenca
I bought a Samsung SBH650 headset BT kit for 49 euros, just wonderful with the HD ! And there's a 3.5mm jack to plug your own earphones.
You can try Jabra BT3030. It has 3.5 connector and suberb design. Quality of sound is no so perfect if you compare to wired connection, but this good compromiss between a player/phone management comfort and sound quality.

Hi,
as you noticed from the signature, after few months of happy use of the Shure Se-110 i got (thanks Pere Noel!) a pair of...
WESTONE3
The problem: my vocabulary is not good enough to describe the feelings they generate
...basses....middles...highs...
The first reaction, is to forget the audio booster and the equalizer, to learn how it should have been in reality...
Maybe the best comment is: It feels like being there.
Forgetting for a second the description of how good they are (check here for better poetry! http://www.head-fi.org/forums/f103/...thing-else-aka-w3-appreciation-thread-386477/ )
One comment specific to the touch HD: forget about the 100 dB limitation unless you bought it in EU (i got it in switzerland) and you are using stock roms. I am actually thinking to cook my ROM (see signature) to be optimized for audiophiles, all WWE ROMS are not affected by this tweak.
Thanks to everybody that answered my original question in the thread, actually the hint towards the westone3 came first from NOBELOVE - thanks NOBELOVE! - you made me see the world in colours!!!
For the best value get the Moto HT820's
The HT820's are still available from several places including Amazon and are only $38 (US)!! Really an amazing piece of equipment for the price. Great sound for music and phone calls and it does have a 3.5mm jack (cable even comes with it).
Oh, disregard my post. I was confused by the OP's question. The 820's are still pretty great for $38 though.

Are you completely sure it does work m8 ????
By beats a presume you mean Dreys Beats?? ....... *sigh*
No offence but they sell overpriced junk to clueless kids who want another 'cool' accessory to match their iphone
If you want good sound quality headphones go to a proper HiFi shop and try some Sennheisers and some other brands ......... you'll probably notice that most of the Sennheisers sound great compared to other manufacturers offerings at the same or often much higher price.
Job done
Please don't get sucked in by the 'Big rap name brand BS' all they sell is overpriced junk. There are proper companies who develop and sell REAL HiFi headphones, Sennheiser, BeyerDynamic, Sony, etc.
Give them your cash and get genuinely awesome sound quality rather than something that just happens to come in pink camo.
Oh yeah almost forgot if Beats on HTC does anything at all it will be nothing but a slight EQ profile change, to accentuate the characteristics of the phones.
Probably just a big dumb low freq boost so you can 'Feel da bass'. Problem is as anyone whos HiFi knowledgable will tell you an EQ really needs setting for each piece of music or at least each style ......... once you understand that you start to realize how useless such gimmicks are and learn to not trust companies behind such junk.
Dunno what HTC are getting in bed with this, maybe their marketing people think they need kid street cred.
The Beats thing is not what you would want in Headphones. I will always want to listen to my music without adjusting the EQ. Personally never liked the over done BASS on the headphones myself, could always find something cheaper that did a better job.
I would always want to listen to music on a iPod so i don't drain the battery of my phone.

Dood DO NOT Just take my word for it .... go to a decent HiFi shop with your phone or MP3 player ( i don't use my phone for mobile music never have ).
Use your own player with your own music and just listen to some different phones and see what you think. Do the same thing with some 'Cool boutique' phones and you'll see what a mean.
I can predict that Sennheisers will most likely be the best 'bang for buck' in full size cans anyways. Their in ears are good too but i don't use in ears myself as am one of those people whos ears get sore in 20mins using in ears.
Oh yeah forgot to say the best sound quality improvement on headphones for less than $20 is a of these

FiiO E5, headphone amp it sits between your player and your phones and acts as a dedicated power Amp. Its about 45x45x8mm with an LED lit on/off button, a volume rocker, and an EQ button flat (FTW), or Bass boost (meh).
They are stupid cheap (thanks to our Chinese brothers )
Usb rechargeable, run for about 10 hours on one charge, improve the sound stage and the mid tones amazingly well.
Also they help reduce battery drain in your phone/MP3 player as you can turn the Amp upto 80%-90% and leave it there and run your player on much lower volume like 20%-40% this can make a huge difference to battery life if (Like me) you pretty much listen to mobile music constantly when your outta the house. Get them for peanuts on ebay they really are awesome. FiiO also make a bunch of others models waaay more sophisticated than the E5 i have, but it only cost me $15. Best mobile music accessory i have ever bought, and i've been a mobile audiophile since the 80's!!!!
I agree... Beatz by Dre are CRAP.... 20 Hertz are the lowest they go..
And for 300$ that whack bass lol
I bought pro American Audio DJ headphones that go all the way down to 5Hz for 100$ and the bass is ridiculous!!!

What Guru Zeb said. It's all a load of gimmicky rubbish designed to part you from your cash.
If you want good audio fidelity it would be wise to invest in Headphones from a company that has been making them for over fifty years. You wouldn't buy a car made by Zanussi after all, although you might have a washing machine from them!
Stick to the known manufacturers like Sennheiser and you can't go wrong.

Curious as to why you need bass down to such a low level, since that's pretty much just moving air at that kind of frequency... I don't really think you would hear any difference tbh, unless I'm missing something

In large speakers yes its just moving air... but have you felt 5Hz in headphones?? Not only does the bass sound richer and deeper but idk the rest of you but I like the feeling of the bass as well and with 5hz you CAN feel it lol

You are right, humans cannot hear 5hz, but that is not the reason for wanting to have cans that can reproduce such low frequencies.
The real reason you want cans or speakers in general for that matter to be able to reproduce frequencies way out of our hearing range is to allow for the rollofs at the limitations of a driver. Every speaker has a limited range of frequencies that it can reproduce, usually some range between 20hz and 20,000hz, but there is a difference between what is "reproduceable" by a driver and what is "useful" in that range of frequencies. As you reach the upper and lower ends of that range you are actually reaching the physical limitations of the mechanical features of the speaker which means that there are variances in the frequency response that reault in what is called a "rolloff" or drop in the output of the speaker at specific frequencies. For example if you have a set of cans that respond fron 20 to 20k as previously described, when tested with measuring equipment you will find that when you reach up around 15k or 16k you will stat to get a drop off in response resulting in decreased volume from those frequencies due to losses within the mechanical reproduction of the audio, say for example a drop of 3db/octave beyond 15khz. While the speakers may still do something, "respond", when you supply them with a 20khz tone, the tone may be very much quieter than a useful volume for music reproduction purposes.
If the response range of the speakers advances a ways past the range of frequencies audible to humans you will find that the response within those audible frequencies will be stro.g at the far low and far high extremes of the range because the driver is not working at the edges of its mechanical limitations. Less energy is wasted as heat because the driver operates more efficiently within the useful range that it is intended for. So while you may not be ae to hear that extra 15 thousand hertz your speakers can produce above 20khz, its purpose is not to be audible, its purpose is to improve the linearity of the response of the audible frequency range.
Now, back to the topic, since im a sound engineer by profession and obviously audio actually matters as a feature to me, what does "with beats audio" actually entail in practice and can it be turned the **** off? I have a funny feeling i might buy the htc one x and i want to be sure that this "beays audio" nonsense isnt gonna actually ruin the audio playback for me as its basically mission critical. As long as it can be completely disabled so it has no effect on playback i will be satisfied.

To answer your question, it's nothing more than a branded EQ and I'd imagine it's just an apk that can be uninstalled or frozen with titanium backup or equivalent app....
The fact that it's nothing more than a gimmick which allows them to slap a sticker on the box and lure in teenagers who enjoying playing Rihanna songs at full volume on their phone in public, makes me think that it will not be so deeply integrated that it's difficult to remove.
Thats exactly what i was hoping.
I discovered after a little reading that the reason htc have gotten involved in the beats audio gimmick is that beats electronics inc. invested $300million in htc. Kinda hard not to slap the logo on for that much money in what is arguably hard times for htc.

Interesting....
Gotta pay the bills I guess...
Beats audio..
Beats audio.
what i think ( and tested ) not the headphones.
But beats audio on your phone has very little to do with the hardware. and no special hardware inside the phone is required.
(ie flashing sense 4 rom with beats support wil work on a desire HD)
Now let me be bold to say that the software "beats audio' is nothing more than a "soft" DSP.
Copanies like SonicFocus / DTS / and Dolby have ben in this for ages and doing asuperb job at it.
Call it EQ, call it an algorithm.
Beats is in fact an algorithm that boost the dynamics, dep bass, brilliance, and solo clarity of the sound.
Creative > crystaliser
SoundMax > Sonic Focus
And i do have to say that with the "beats audio" enabled it does sound bigger and more clear.
But is it still safe to say that with compression of mp3s or even streamed music the quality of the sound could get just a little dull.
( at least that is what I notice )
Not thats where the DSP comes in, may it be beats, sonic focus, or whatever. I think on a mobile device playing mp3/streamed audio it does enhance the sound.
conclusion.
its a soft DSP, with its own fancy name and logo. A DSP that should be in that device anyway.
A nice marketing gimmick.

You are right, humans cannot hear 5hz, but that is not the reason for wanting to have cans that can reproduce such low frequencies.
The real reason you want cans or speakers in general for that matter to be able to reproduce frequencies way out of our hearing range is to allow for the rollofs at the limitations of a driver. Every speaker has a limited range of frequencies that it can reproduce, usually some range between 20hz and 20,000hz, but there is a difference between what is "reproduceable" by a driver and what is "useful" in that range of frequencies. As you reach the upper and lower ends of that range you are actually reaching the physical limitations of the mechanical features of the speaker which means that there are variances in the frequency response that reault in what is called a "rolloff" or drop in the output of the speaker at specific frequencies. For example if you have a set of cans that respond fron 20 to 20k as previously described, when tested with measuring equipment you will find that when you reach up around 15k or 16k you will stat to get a drop off in response resulting in decreased volume from those frequencies due to losses within the mechanical reproduction of the audio, say for example a drop of 3db/octave beyond 15khz. While the speakers may still do something, "respond", when you supply them with a 20khz tone, the tone may be very much quieter than a useful volume for music reproduction purposes.
If the response range of the speakers advances a ways past the range of frequencies audible to humans you will find that the response within those audible frequencies will be stro.g at the far low and far high extremes of the range because the driver is not working at the edges of its mechanical limitations. Less energy is wasted as heat because the driver operates more efficiently within the useful range that it is intended for. So while you may not be ae to hear that extra 15 thousand hertz your speakers can produce above 20khz, its purpose is not to be audible, its purpose is to improve the linearity of the response of the audible frequency range.
Now, back to the topic, since im a sound engineer by profession and obviously audio actually matters as a feature to me, what does "with beats audio" actually entail in practice and can it be turned the **** off? I have a funny feeling i might buy the htc one x and i want to be sure that this "beays audio" nonsense isnt gonna actually ruin the audio playback for me as its basically mission critical.

This is exactly right.
The numbers relating to audio that are posted on headphone and speaker boxes are a mess, they all proudly proclaim 20-20k, but realistically they're defining an edge on a smooth curve. The point you made about linear amplification bears to be repeated: the phone is going to contain the driving amp, and the ideal amp would produce a square wave at your nominal impedance, where the amplifier will simply not push any frequency below the lower bound, then push exactly X dB at each frequency for the entire supported frequency range, sharply dropping off again to never push any signal above the upper frequency bound.
The actual bounding values that the amplifier covers are irrelevant because the physical limitations on what frequencies silicon can push are far outside of your audible hearing range (no you cant hear 20Hz, I know your science 8 teacher told you you could but he lied, you have superb hearing if you can hear 30Hz, furthermore none of my music produces sounds above 16KHz).
And that's only speaking to frequency response, which, while arguably the most important characteristic of an amplifier, is certainly not the only one.
Somebody before this post suggested getting a Fiio E5 headphone amp, I've used one of those and they really do help if your trying to drive 100 Ohm+ headphones, which almost no ear buds are. If your wandering around with Senny 600s or AT 900s you might need such an amp, but for the most part the amp built in to the phone should suffice.
I hope the thing that a "beats [certified amp]" means is that for some given load (read: headphones to drive) the amp must produce a reasonably constant dB / frequency curve. But looking at beatsbydre.com/beatsaudio/Beats%20Audio,default,sc.html, it really does just look like yo dawg, this stuffs dope, we promise.
as per Enonoid, I'm wondering if its just software and/or a DSP. I haven't used any beats audio stuff before so I cant speak to it, but the "Crystalizer" feature on modern X-Fi stuff is actually kind've nifty. Its claim is that intrinsically its very difficult to encode percussion, and so when decoding you should have filters that smartly look for percussion and attempt to create the true audio-spikes they entail, rather than the wash they frequently get encoded as. Its a novel concept, and I'd even be willing to argue it adds something to the sound, and if beats is just something similar, I guess I'm on board, as long as it isn't simply slanting an EQ to boost everything below 500Hz.

Why still no USB audio?

Seriously...I want USB audio support for my damn phone already... Do I really have to sell my galaxy note, and get a damn iphone for this feature that should've been here YEARS AGO?
Our phones have the worst DSP/DAC ever...
Every post I have seen of yours has just been *****ing and moaning about this phone... not once have I seen a productive/informative/helpful post from you.
why don't you just sell it already and go back to drinking apple koolaid then?
LOL
Why not just use a 3.5 mm aux wire for music and leave the usb for charging in the car? Problem solved. Although, you would have to change tracks on the phone instead of the car's head unit. There are requests to google since a year ago, we might see it in Jellybean.
I agree, *****ing and moaning wont do much. If you cant stand having this device, sell it and get something else.
-Once you go NOTE, you'd say 4 inches a Joke
go bluetooth bro. it works awesomely
Explain how I said everything about the phone sucks?
Btw, I'm an audiophile. The DAC in our phone garbage. How is it so much to ask for a USB external DAC option for my phone? Iphones had this feature before they had MMS. You say i drjnk Apple koolaid whdn i sold m iPad to get this phone?? SAMSUNG's specs said this phone had USB HOST 2.0... I bought it thinking that I'd be able to use a USB DAC with ICS which was shpposed to be released for our phone MONTHS AGO. Is Apple se, retly paying google to not have USB DACs available for android? How am i supposed to have use my hifi audio systems with my phone? And dont say bluetooth because bluetooth is not HiFi. The 3.5 mm is not an option because it cannot be a line out. Honestly, i wish we had an optical TOSLINK imside our headphone jack, which would solve my problem. This is retarded that we dont have this simple feature.
Btw this is the only thing that really would make buying this phone a dealbreaker for me. I cant ever go back to Apple but I'd like to have my phone have the ABILITY to produce lossless audio and do NOT tell me how MP3 isn't lossless because i know this. I plan on acessing VLC flac files from my home network in the future.
This is in the top 10 issues of google's entire list and they respond by saying basically if someone codes it for them then they might look i to it. They MIGHT... Are you kidding? Most audiophiles who have iphone would switch over for a droid and USB DAC in a heartbeat. Apple would lose a couple hundred thousand customers for writing a few lines of code for ICS...

Besides a DIY project, may try the MHL-microHDMI link to and audio input. Most manufacturers don't seem interested in making anything but apple's 30pin audio components. My Pioneer Dual Din Bluetooth Car Stereo has a USB out the works with Note. Have to use the phone to control it though.

Sell it and shut the effin up already and quit wasting space on this forum
I love my Note, but I keep an old ipod permanently connected in my car just for music. And I have my old iphone 3G, which is only worth $50 at best, is attached to my hi-fi system at home.
Who says you have to do everything with one device? If the Note doesn't do what you want, keep your note and buy something else to do the other job. Just my $0.02.
i'm no genius - but doesn't the MHL adapter provide HDMI audio out?
wouldn't that imply that you CAN get HiFi audio out to your AVR or amp ?
then again, what do i know
If you are this anal about high end sound use store bought CDs. That or a record player and you won't need a DAC.
I love audio way more than anyone I know and I stream blue tooth audio from my phone.. Is it the best sound? No but it gets the job done. If you want high end you need to right equipment. Sadly the Galaxy note doesn't currently have the ability to do this.

Not really correct. Using the original BT compression algorithm, SBC, you get the equivalent of a high-bitrate MP3 - a maximum of 768kbit/s shared between channels and overhead so probably closer to a 256 MP3. There is a newer compression algorithm apt-X which provides lower latency and even higher quality at 384kbit/s. Overhead isn't included in that bitrate so that is the actual throughput on the audio channels. Not lossless (if that is your definition of "HiFi"), but you would have to do a side-by-side comparison to nitpick out the very minor differences.
The 3.5 mm is not an option because it cannot be a line out.

It may have been a bit of an understatement, but considering that windows is something like 62 million lines of code, a simple driver for enabling usb audio when we already have USB host 2.0 wouldn't be very much in comparison, when it should have been implemented in the first place..
Honestly, if anyone gets full linux to ever work on the note, I'm going to use that and never look back if USB audio works with it, and has s-pen support to control the mouse. I'm pretty sure that would happen LONG before android ever gets universal usb audio.

I actually thought that bluetooth audio had less bitrate, but I want the capability for lossless audio streaming from my home network using FLAC files, and the ability to watch blu ray stored on my pc over LTE would be badass as well, without audio comprimise.
Integrating TOSLINK hidden inside our headphone jack isn't has hard as you think. Many RCA and 3.5mm connectors have toslink hidden inside them from laptops and other devices, my sound card has it in the RCA SPDIF out. All they would need to do is make a proprietary android plastic mold adapter which being slightly different shaped than a headphone jack, would activate the TOSLINK switch inside the headphone jack and allow it to be on only by plugging the proprietary adapter inside, saving battery. TOSLINK can't be affected by EMF interuption. If this started happening, many things in the mobile market would change. Apple would lose hundreds of thousands of customers from the audio quality standpoint alone, more audiophiles would emerge from everywhere. Speaker development would increase exponentially. Hifi iPod docks would include TOSLINK. High end headphones would start coming with portable amps with Line Out, TOSLINK, and other options. It would be the easiest way to connect to a home theater system for high end audio. more people would be making their desktops a home server with all the audio stored on it able to stream over LTE. More people would be interested in FLAC and better bitrates. OTher companies would be profiting, driving BOSE into the ground. Companies like JMLAB, Legacy, Theil, Velodyne, Celestian, PSB, Focal, and many other high end companies who deserve more market.
I think it's a little stupid that on a device with a screen as nice as ours, we have little to no audio options available, when audio should have been the first concern in order to manipulate the market. Almost nobody who owns our phone even realizes just how good the display actually is. The black levels on our screen surpass almost any TV ever made, even if the colors aren't perfect. For example, I have a 55 inch 720p Sony Rear projection triple LCD panel tv with less pixels then my phone screen. The black levels on the phone DESTROY my tv, even if the colors aren't near as good on the phone, for cinema, it looks way better a foot from my face than optimal viewing distance with the HDTV. and, the colors on the HDTV surpass that of ANY "LED" tv you will see scamming the market today. They are LED backlit garbage twisted nematic LCD panels with terrible color accuracy.The sony has almost as good colors as my $700 Gateway FPD2485W professional S-IPS photo editing monitor actually, but still not quite. despite this, the phone still looks way better because of the black levels and sharpness, brightness and overall quality of the screen. I think Samsung solved the color problems with SuperAMOLED Plus with a different sub pixel layout amongst other improvemnts

Do not ever plague my posts saying insinuating that I'm a BOSE or Apple fanboy. I am a fanboy of nothing, besides maybe the Dodge Viper. My car sound system might've only cost me $350, from amazing creigslist deals, but it'd run me over $1200 everything brand new with a shop install. I might only have cheap polk 5.25" paper cone door speakers with only 45 watts RMS but they have 93db efficiency which is outstanding for the size, and swivel mount silk domes for clarity. my Alpine 6x9 in the back also have silk domes, and my Alpine 12" kevlar reinforced pulp cone subs might only be 400 watts RMS,but they sound damn clean for the price I stole them for off creigslist, and the custom box they're in is well enough built that even being a vented dual 12" box, if you physically tap on one woofer, the other moves like a well built passive radiator. The component speakers are driven from an MB Quart RA4200 100x4 RMS 0.5% THD amp, which is when rockford fosgate owned MB Quart, and had some quality stuff.
Then again, my home system is better, and while I only have a surround sound system comprised of my HTPC using analogue out from my Auzentech X-FI Home Theater HD, which is one of the best cards ever made for it's purpose, a few 5" Kevlar woofer, Class AB active 1" Silk dome M-Audio BX5a studio monitors, they definitely have clarity. but, my Velodyne ULD 18 is what brings my theater together. You may not understand this, or understand why, but an 18 inch woofer producing [email protected] 20Hz with 0.5% THD (Total Harmonic Distortion) with under a QUARTER INCH of excursion, using a standard tar reinforced pulp cone woofer, with a servo attached to it to achieve this, is no easy feat considering the sub was made before I was born, in 1989. It was the first subwoofer ever to get a class A stereophile review. not only that, but it's flat down to 14Hz and will still push over 120db @ 20Hz with well under 3% THD. This is impressive for using only a 400 watt Class B servo amplifier. The bass quality of my theater makes my car sub which people seem to think is amazing hearing it sound like complete garbage. it makes my sudio monitors look like garbage, and anything bose has ever made sound like garbage, and it's the only piece of audio equipment I will claim to be true quality, everything else, I consider mediocre, because I can't afford a $4,000 pair of ATC bookshelves, or a $30,000 pair of JMLAB Utoptias..
But for the price I paid, I got decent enough quality, and my headphones I use (Sennheiser CX6 for fidelity, Vmoda Crossfade LP for soundstage and bass/electronic music), you can't ever tell me BOSE is quality. Maybe the BOSE 301's are good, I don't know for sure, haven't head them, but everything BOSE Iv'e ever heard was garbage for the money, and I had the tri port headphones, I had the quiet comfort 3's both as a gift. I'd never pay for anything bose has ever currently made, but who knows, Ford finally made something awesome with the new mustangs, I could change my mind eventually.
Point is, I mostly know what I'm doing with audio.

The lack of navigation really pissed me off, the interface and texting pissed me off, the tiny screen pissed me off. I ended up deciding to sell the iphone and ipad to get this Galaxy note, which was worth it in every aspect except the terrible audio options available and the fact Samsung ripped us off on ICS release.

I ended up deciding to sell the iphone and ipad to get this Galaxy note, which was worth it in every aspect except the terrible audio options available and the fact Samsung ripped us off on ICS release.
Pretty crappy for my standards but w/e
Ehh, only really good piece of equipment in these pics is my good 24" monitor, and my Velodyne ULD18, and they are kind of old but I don't have any good new pics..

3.5mm jack is very bad quality! (or just software?)

I was really hoping to get at least normal headphones output from poco x3, its a poco device, no? I've used poco f1 for 2 years now, sound output from 3.5mm jack was nice and loud (at least), im using it with blon-03 and sound is, man, i cant listen to it more than a few minutes (ear fatigue is horrible). Can't believe that anyone didn't noticed this BIG issue.. cmon i havent heard such a bad sound EVER. Tried to use xiaomi's headphone presets, equalizer, sound calibration.. not even close .. after a few days (after update) tried it once more, aaand flashback, sound is simply said non usable. NO BASS, MIDS PAINFULLY SHARP, EAR PIERCING HIGHS.
im deeply disappointed, if this ENORMOUS issue is due low quality 3.5mm jack... not just software (writing this with fisical PAIN in my ears)
Nah its not that bad need some Viper to boost it and schould be fine ofc depends on what headphones you use maybe u need some external amp and dac idk

as i said.. on poco f1 i didn't expected hi quality dac, and i was satisfied with sound quality and loudness, i use blon 03 earbuds (iem) and there's no bass.. and overall quality is not good... ill try some apps, maybe it will help
Might be a dumb suggestion, but make sure you're actually plugging in the jack all the way in. I've heard complaints before on other phones, and the reason was because the last 0.5mm was not pushed in. Often times cases can block the full engagement of the jack depending on the design.

tried it immediately when i heard the deference between poco f1 and this one (poco x3)..tried to install some app (beats).. nothing.Dont get me wrong, I'm not picky, just sound quality isnt there..quality is LOW, tried another pair (also iem quality) of earbuds and they sound BAD.

Didn't Xiaomi specify that the POCO X3 was HI-Res Audio certified?
I'm having doubts as to whether I should buy this phone. I want that sweet 24-bit/192kHz audio!
I'm still waiting for my phone to arrive, but this would be one of the first things I check. That said, there is a small possibility that your jack may be defective, or something else going on in the background. I've had my fair share of cheap crappy mp3 players in the past and the worst sounding DAC I've ever experienced was still passable to 99% of the general public.
This review of the Poco X3 tested the frequency response from the DAC and it looks perfectly fine.

What you described in the opening post certainly sounds as defective. The typical deviation in phone DAC quality is usually very subtle and only noticed by a very small subset of people with high end headphones. There is definitely something wrong if you are getting "NO BASS" and ear piercing highs.
Is anyone else experiencing the same?
That sounds like a defective unit, either that or you're VERY picky.
I don't know with other people but for me the sound quality is good with punchy bass, mid is quite good I can hear it clearly and high is good and details. Overall I'm really satisfied with the sound quality :good:
Can someone confirm the audio output quality via the jack by comparing with other devices.
Would really help me to make my buying decision ;/

one thing happend... i was reading your reply, and i had to try it again, blow the 3.5mm just to idk, do something... played music again, and i was like WHAT,? theres bass... i can't believe it.. sound for some reason got better.. i cant understand it. Day Before i also checked that the plug was properly inserted and it was,.. doesn't matter, its working ok now.

V60 dac distortion problems

Hello to everyone,first post.
I am stuck with a very peculiar problem, I hope somebody can help me here.
I have the v20 (my daughter inherited it), the v30 (as backup), my wife has the v50 and I just bought a v60. The musical experience is a key feature for us.
Now, I have a maddening issue with it. After setting it up, i immediately noticed that it sounded distorted when playing certain songs from tidal.
I have a pair of etymotic research er2xr iems and a custom made ciem pair (75 ohm impedance) that literally blows the er2xr out of the water.
However, I started listening to classical music, it began to drive me nuts. There is constant distortion when playing high frequency piano parts (Chopin for example). I have tried different sources (tidal, my own collection in various resolutions) and they all produce the same distortion.
Other than that the sound quality is awesome. That is the strangest thing.
With the er2xr it is less pronounced but with the more revealing ciems it is simply not enjoyable.
I have done my fair bit of research (read about tidal watermarks etc. ) , I have tried the ciems with the v50 and the others, they sound fantastic playing Chopin. I even tried them with my desktop dac without issues.
My conclusion is:
- the dac has a problem (that's strange because only one frequency range is problematic)
- the dac has been tuned like this by the factory - that would also be strange as obviously other people would listen to classical music on it and they would definitely hear it.
I would really appreciate it if someone could add their opinions and tips.
I bought the phone from Germany and it's covered by warranty but it would be a hassle to send it back, let alone explaining the problem to them as with the oem iems nothing is audible.
Other than this and the occasional dual screen flickering issue (that has to do something with UAPP player) In love this phone and would like to stick with it.
The V50 sounds very different (darker I would say) and it is better tuned in my opinion. All other things, however, are better on the v60.
Thanks for every suggestion.

I don't have Tidal but I can test the tracks on my V60 and G8 through Deezer (lossless CD quality). I'd be using the Focal Clear and HD800s. I don't really have IEMs other than a pair of Klipsch X10.

I have some experience in this same subject but I would rather talk about it on the LG discord. To make it short, I have had 3 different V60 units and can confirm 1 sounded very distinctly different the the other two. All 3 units had the same distortion (usually on lower freq's in my case) you are referring to that I could confirm with my pair of IEM Audiosense T800. I also have had every V series device including 10, 20, 30, 40, 50, and G7 and G8. I agree the V50 sounded darker bolder, more closed in and personal to my ears at times, the V60 seems a bit more detailed and brighter. I can expand in more detail of my findings and I still have my G7 to compare to back and fourth.
Thanks for the replies. I have taken the phone to an audio engineer and had it checked by oscilloscope. It seems to be working fine, no clipping. However, when connected to an external sound generator the noise was clearly audible, which would lead me to think that the iems have a problem. Btw, I modify my earlier assessment, it happens when there is an attack, for example, and low and high frequencies are played together. The sound generator showed that it's almost always there but clearly audible from 200 Hz to 600Hz.
Then I went back to the guy who made the custom iem.
Findings are the followings:
- the noise is definitely audible when using the v60 with the ciems.
- no noise is audible when I listen to the v60 with other professional grade iems
- no noise is audible when using the ciems with a cayin n8 dap or other players
The above seem to contradict each other.
The ciem developer says that the ciem and phone are just not compatible. I tend to believe him, if such a thing exists, at all.
Hi, before I saw your post I made a thread about what seems like the same issue on my Bell Canada V60. I first noticed it playing Chopin piano, lol. It's very clear playing piano tracks. I have a binuaral beats app that can generate a signal and I can hear it as well. It's only there Somewhere between minimum and maximum volume and only when HIFI Quad DAC is enabled. I was begining to think I have a single hardware defect associated with the Quad DAC until I saw your post. What firmware are you on? I'm on V600TM10q
Here is my post: https://forum.xda-developers.com/t/lg-v60-quad-dac-issues-with-noise-and-distortion.4227291/

Hi,
This thing is really driving me nuts. I had the V60 measured with an oscilloscope by an expert. He didn't find any distortions or irregularities. I have replaced the ciems with a more expensive pair. The high noise floor (or background noise has disappeared) but it has developed a new problem since then. It started to randomly give a mechanical popping sound which is not consistent (doesn't always happen in the same tracks). The developer of the ciem is certain that the problem is the V60. I am not convinced about it.
Nevertheless, yesterday I went and sat down with the developer of the ciem to show him the problem. Guess what! I sat there for an hour and no matter what I did I couldn't reproduce the problem. Then on the way home in the car, it reappeared again. It is audible if you turn the iem around and only listen to the faceplate from the outside it sounds something like a cricket (only slightly mechanical) . Then the same problem occured with my wife's V50., too.
So, I think the problem is with the ciem not the V60. On the other hand, the first pair of ciems definitely worked and listening with my wife's er2xr I heard the same problems (high background noise) only less audibly.
Basically, I am stuck between the V60 and the ciems. I could return the V60 under warranty, but I am afraid I would only make a fool of myself as they would not be able to hear the problem. It is like chasing ghosts.
To sum it up, I am leaning towards the opinion that there are certain iems that have an incompatible frequency response curve with the LG V60 (it is important to note that the V50 doesn't have the same issue).

Hi Adamcs,
I have an USB external dac "Topping NX4 DSD" and other devices as well. Ive compared the v60 with 4 different headphones with different impedances. The issues are not present when I use an external usb dac with the v60, I dont hear them with the internal Quad Dac turned off. For me the issue is the way LG decided to auto unable the Quad Dac for different headphone impedances. (Above 50ohm I assume).. And the way they tuned the v60 dac to handle them. It seems with certain headphones, more sensitive ones, the issue is more obvious. Painfully obvious with Quad Dac on and Sony Mdr-7506 and solo piano tracks, Chopin for example. I still like this device even though Android 10 has its issues. UAPP is a big help there even if not perfect. In my opinion, its not the headphones and not the v60 all the time, seems like the combination of its Quad Dac and some headphones. I'm still a little confused but im starting to get a more clear picture of the situation after a lot of troubleshooting and reading other posts. Hope it helps you.
I wish I was there when your expert measured it with the scope, wish I owned one tbh. I know how to produce the conditions for the noise distortion to appear every time using a signal generated wave. Measuring it would be really interesting.
PS. I just played a random track with UAPP and Tidal, Olivia Dear - Halfway, and the distortion is immediately noticeable from the start. Its like the bass crossover leaks into the treble and its incredibly noticeable with Sony Mdr-7506( kind of bright pro headphones I use for audio editing, mixing etc..) Turn Quad dac off and theres zero distortion present.
I have experienced this issue as well, and have taken some measurements. This is the first 10 seconds of 'The Last Geisha' by Isidor. Top in both pics is Quad DAC on, lower is DAC off. Obvious, measurable issues with this phone. I'm rather upset by this, as unless my device is defective (or should I say, OUR devices) then either ESS or LG screwed something up, and this phone has zero right to be considered 'audiophile' at all. Considering trying to use my warranty to get a refund, or hopefully a replacement without the issue.

Have you guys tried to confirm whether your V60 identifies the earphones as audio devices or just "external device" and see if it makes a difference? You can tell the connection type by the app Hifi Status (LG).

My V60 is always in high-impedance mode with my headphones, and that's when I notice distortion. I recall doing my distortion test on a pair of Carbo Tenore IEMs. Gain was not in high-impedance mode (normal audio device). Didn't hear the distortion. I'm not sure how to make it go into external device mode.
By the way, if we want to be sure that we're talking about the same issue, I can only hear distortion when the volume is between 30-50 and the Quad DAC is in high-impedance mode. The distortion affects the left ear much worse than the right, but right still has a little bit going on. Distortion only seems to happen on specific tracks that rub it the wrong way, like The Last Geisha, as I mentioned above.

Try using a recording, wav, HDCD or a higher resolution lossless file type through Poweramp and see if you can dial the DAC in with many audio processing options. All DSP engines are not create equal.
Might be some sort of artifact present in the TIDAL music not your hardware.
With piano and especially harpsichord music artifacts are easier to detect.
Ideally you should use a stereo open air driver system ie a set of monitor speakers in a acoustically suitable listening area in order to fully reproduce the soundstage... or hear the lack of it.

That the artifacts disappear when the Quad DAC is turned off leads me to believe that TIDAL isn't the issue, plus the other streaming services I tried. Believe me, the distortion artifacts are very audible with headphones. I'm using Clears and HD 650s. Soundstage was never an issue, just the crackling sounds that come from the peculiar crossover distortion.

Yeah that doesn't sound good. If you have Developer options you could look at what audio options are available. Double check the settings.
Since you want to listen to music and know the difference... it will only grate on your nerves more as times passes. I toss it back.
Sorry you're having so much trouble.

I'd return the phone to the merchant if you're still in the return window or initiate a warranty exchange with LG.
