As Sony said that the Digital Noise Canceling Function in Z2 reduce a noise to 98% when you listening a music with your headphone or headset, Do you thinkthe Digital Noise Canceling in Z2 will work if Z2 is in your pocket? Because I and my friend think that the work of this function is the phone measure and analyze a sound around Z2 with its microphone and then when it gets a result, it will tries to reduce that a noise sound to make a sound in Z2 clearer and better. So, If we put Z2 in our pocket,I think this function will work improperly in reducing the noise sound.
this function might be work if we set a mode (bus/train,etc.) in this function manually not let this function do by itself (auto),
What do you think about the work of this function?
I think it should work fine in your pocket. The phone is only doing the calculations necessary to do the noise cancellation. It is using a microphone built in to the headphones to gather the ambient noise, so it will not be affected by having the phone in your pocket. That's why you need special headphones.
Yes, it will. It registers the ambient noise through microphones built into the headphones - microphones built into the phone itself are not involved in NC process at all.
Does every z2 come with the noise canceling headphones or it's only for the people who preorder it?

For now, Sony confirmed to bundle them with pre-order stock. No word about what's going to happen after that.
My guess ? They will keep including them because NC is a big selling point of Z2 and not including the headphones wouldn't make any sense.
i
Noise-Cancellation is a process for mechanical wave (Sound)
whenever these waves get into this process Noise-Cancellation machine (or sensor) will make opposite waves of them wherever phone be in ur pocket or on a table. If there s sound so there s noise-cancellation

I can confirm that the noise canceling is using one microphone on each earbud. These microphones are also used for your speech when making calls. To work, the headphones utilizes a new, 5-pole connector (and of course some special firmware in the phone).

Did you have a chance to try them out ? Would love to hear some feedback on how the noise cancellation actually performs while listening to music etc. as it's one of the main reasons I'm upgrading my original Z.

You have three settings to choose from: Office, Train/Bus, and Airplane. The noise cancelling is especially effective, in my opinion, for the kind of "drone" you usually will suffer from on aircraft. In the office, voices will become significantly dampened, but not completely extinguished - you will still perceive people talking loudly to you, but you might have totake them off to hear what is being said.
The sound quality shall generally not be affected by the noise cancelling, and I at least cannot hear any difference in that regard whether noise cacelling is on or off, except of course that any outside disturbance is reduced.
When it comes to the sound quailty in general, that is very much a matter of personal preference. Our noise-cancelling headset will be especially attractive for those who prefer a strong bass experience, while I personally prefer a more balanced reproduction even if that is not so exciting to dance to. I suggest strongly that you try to listen to them, and compare with other headsets, before you buy; its horses for courses, so to speak.
Thanks chief. I'm definitely getting the phone anyway - might not use the noise cancellation feature sometimes if I don't like it - but from what you're saying, it's exactly what I expected. Never believe that any noise cancelling can extinguish ALL the ambient noise, but as long as it doesn't muffle or distort the music too much, and sound quality is decent ( I love the bundled headphones I received with my Xperia Z ) then it's all good.

Interesting piece of information here..
So can we safely say that headphones without microphones will not work at all for NC? I wonder if there's an option to use the mic on the device itself for NC.

Yes, we need compatible headset for NC to work. Sony offers 3-4 headsets that support that, the one that is bundled with the phone and a few others - I assume some of them are or will be wireless etc.
There is, however, no way to enable NC with no headset plugged in - which makes sense because it would give no benefits at all. And the same goes for headsets that are not equipped with mics and a 5 bolt connector.

Nope. The mic built in A-Jays is for calls only.
That's just bollocks! (pardon me)
Sony marketed the Z2 with a NC built into the phone to reduce the bulk and what not.. but it seems to come with a catch.
The mic on any earphones can be accessed for any purpose. Unless there is a certain mic spec to follow to achieve NC....
Just hoping the package we get in my country comes with NC compatible earbuds..
Sony NC earphones have 5 poles on the 3.5mm connector. thats 2 more than other earphones and is used for NC. I am not aware if there are other earphones with 5 poles

Yes, it's true. That's why I said I strongly think and not for 100% sure (but I think it will be pretty "funny" if it doesn't). Maybe if you connect it with the NC31 profile will work with it, I don't know. Personally I hate what Noise Cancellation do with the sound, so I prefer the passive one instead of the active.

Hi all! I have been reading alot of post about Streak's low quality sound output, and I'am experiencing it too, when I plug in my head phones there is no hissing sound, but when I click play or receive a call hissing sound starts and does not end till audio output end.
There is alot of post from people that have the same issue, I will Quote them below. I'm posting this because everyone that has posted this issue has been "overrun" with other people posts that they do not have that background noise.
I just want to expand on this problem, could it be Android version, or perhaps different hardware? Any suggestion is welcome.

Hi,
Personally I find that whatever I use as earphones, I have a hard time accepting the noise level on the streak. When playing music at a medium volume, the noise is really very very present.
I suppose there is no work around is there? Doesn't this bother you for serious listening?

The sound quality is absolutely abhorrent in comparison to the Galaxy SII or any other smartphone I've ever used, including the HD2, Vibrant, several Nokia devices, etc.
There is a constant and definitely audible signal noise in the Streak that really bugged me. As a recording engineer, I can definitely hear the difference between the audio systems on the two devices. When the playback system kicks in, you can literally hear the hiss in the background. When the playback stops, the hiss vanishes. Upon further investigation, it seems that this is a known issue that found its way into several reviews. If I hadn't heard it for myself, I'd have not believed how terrible it actually sounded, and frankly, it's SO bad that I find it inexcusable on such a high-end device.
I sold my iPod and bought a larger MicroSD to use my phone as my main portable media device, and the Streak really let me down.

I'm having the same problem. Hissing noise in the background. I also got mine couple days ago. I bought it when it was $200 unlocked from dell.
I'm on stock 347. I should have tested the earphone when I had 351.
It makes the hissing noise in music, internet radio, wherever sound is being played. It has a constant level of hiss noise even if I raise the music volume or reduce it to minimum.

I believe it's the hardware. Doesn't matter what OS level you're running (I've experienced it on 2.1, 2.2, 2.3)

I hope its OS because some don't have this issue, maybe MIUI 2.3.2 Rom wont have this problem (when they fix the problem with headphones not being recognized).
And yes, on Dell oem headphones it is less noticable but compared to 50-100$ better headphones, Dell's are low quality, although they are one of the best in box headphones that comes with device.
I have some basic knowledge in Java and C. Could anyone point in the right direction so I can try to edit/tweak some setting of audio output. Any info would be appreciated.
It's also noticible on the S7 and venue. At least on the S7 you can only really notice it in a room that's completely silent, but at least for that i'm talking about the external speakers.
All I can say is that it's pretty much not noticible for me as long as it's not silence/very low volume music. At least for me it's very easy to drown out the hiss by raising the volume as it does not/minimally scales with the volume.
Keep in mind that the speakers/headset jack simply do not recieve power when not in use, the hiss on them could be part of the inherent design of it. It might be noise after the DAC as it doesnt scale anywhere near 1:1 with the audio. But I'm just blindly guessing

The V has pretty much no perceptable hiss, and I believe the V and S5 share the same audio drivers (dont quote me on this), it might merely be a hardware issue on the S5.
I cant really say much about the S7's headset out, as it's rather unwieldly to use that way.
Also I'm very sure that it ISNT dependant on volume, like previously mentioned unless your current headset is loud to begin with, just turn up the volume and it drowns out nicely.
But yes it will be noticable on the quiet parts of music or during track changes.
tl;dr: turn up volume, V's got a cleaner output
Equipment tested on:
S5: CM7.2
S7: SD7-r9 (514-xx)
V: SD4-250 (408)
headset: iphone in ear headphones
I think its just the poor SNR ratio of the streak, its only -79db or something, its very poor.

Makes me sad
The noise cancelling headset MDR-NC31EM, does it have a microphone? If yes, where is the microphone?
Another question is what the difference b/t "Noise cancelling (Auto)" and "Noise cancelling (Always)"?
Thanks.
1 I think the mics are on the earpieces
2 I would like to know this too
Sent from my D6503 using XDA Free mobile app
The microphone(s) is in the earpiece.
About the difference between the 2 settings:
"Auto" turns on noise cancelling only when you unlock the phone. When the phone is locked (or screen is turned off) noise cancelling stops.
"Always" means... always. From the moment you plug the headphones till the moment you unplug them noise cancelling in on.
Hope that helps.
Binaural recording
Have anyone tried to record stereo audio using the MDR-NC31EM earphones? Maybe it's possible to do a binaural 3D audio recording through it.
Have you guys make calls using this headset? Many people whom I talked to using this headset told me that it is very noisy and cannot hear my voice properly. Anyone has this issue?

Well I don't have this problem. I switch it to "Auto", and when I make a call, the noise cancelling function seems to be reduced a bit so that the voice of the one talking to me will not be eliminated too much.
This is indeed very unclear.
I was testing it with a friend just now, and when I rubbed my fingers over the microphones on the earpieces they could hear the disturbance. This, to me, seems very strange. If the microphones are pointed outwards, then all the god damn sound around you will be picked up and get sent to the other person. How is that noise cancelling?
What am I missing?
I think I had the noise cancelling set to "Always", but even if it's on auto, the microphones are positioned in a very stupid way. Am I right?

That isn't the case. Auto just means that your phone will try to judge what kind of environment you're in between the three manual presets (airplane, bus/train and office).

The noise cancelling isn't really made for calls, it's for cutting out unwanted noises while listening to music.

Hands-free calling
When a call comes in you can use your MDR-NC31EM to enjoy the call. Your hands are free and you have excellent call audio.
Note: call handling is only possible when the MDR-NC31EM is connected to a device with a 3.5 mm 5-pole audio contact. Check your device specifications for details.

I don't think that you're supposed to switch out headphones when a call comes in. That'd be... strange.
When i want to talk with this headset, i take out one of them and speak to the earpiece. So can the other people good listen was i said.
Just wanted to know if anyone else noticed faint buzzing/scratching/hissing noises coming out of their headphone jack...
(and yes I have tested several headphones/earbuds and tested with my MDRv6's all with the same results. Its definitely the phone not the headphones)
When I insert my headphones there is a quick beeping sound that plays for a second or so then goes quiet.
When music is playing, especially soft music (a particular song was Instant Crush; Daft Punk) there is a hiss in the background, specifically when certain tones play.
It was terribly noticeable right at the beginning of a few songs, especially the one I listed above.
I also have button sound effects enabled. So When I press one of the soft UI buttons it makes a tick noise. However for about 5 seconds after the tick there is a long hiss then silence until I press another button.
The volume of the hissing/scratching noises is directly related to the actual volume of the device and the note playing.
Im on stock build 11c w/root, and I havent found a lot of info about this problem.
Just wondering if anyone has noticed this, or if this is a known issue?
If your phone is warranteed, I would bring it in
The G3 boasts an AMPLIFIED 1 watt sound speaker, which means there is a powered sound processor.. Unless the jack needs to be cleaned, I would lean toward thinking there is a defect in your phones jack, or sound assembly. I think its more than likely a defective jack, especially if there are no sounds like you are describing when headphones are not in use

Just got my G3 a week ago and didnt use headphones until I read your post, I tested many different songs with different players, stock player, google player, Iheart radio, pandora, etc, headphone sound is crystal clear on mine, I dont get any beeps either like you described, I did notice you need to make sure the jack is pushed in good and tight, I put it in and thought it was all the way in and sound was crappy, pushed a bit harder and it clicked in good and sound was great, do you have a case that may be preventing the jack from being pushed in all the way, I had a phone in the past that this happened to me with, had to cut away some rubber on the jack to make it fit snug, if none of those are the issue, I would look into a warranty claim. I am using the beats audio earbuds that came with my HTC M7 I had before this phone.

That could be the issue. I know on the 2012 Nexus 7, it's really bad. It's supposedly due to the microUSB port and the headphone jack sharing the same circuit, or some engineering thing like.
Wonder if it's the same or if they didn't shield the headphone jack very well and it's picking up interference from the microUSB port when charging?
I didn't want to leave this up in the air so I figured I would post an update.
I replaced my G3 through Verizon for a brand new unit. My first phone was of an earlier batch (came with the 10b update) the second one was of a later batch and had 11b pre-installed.
Both phones had the same issue. There is a hissing noise/distortion that comes from the headphone jack. Even when not playing music.
I noticed it on other phones too but not anywhere nearly as much. I understand that any audio source is going to have a little background interference but the G3 definitely has a more significant issue than others.
However it seems to be entirely dependant on what headphones you are using.
1st. I tested first with my Sony MDR-v6's which the problem is most noticeable on. Extreme hissing/background noise.
2nd. Then I used a pair of Audio Techina ATH-PRO500's and the problem was almost unnoticeable.
3rd. I also tried my Steel Series Siberia v2's and the problem was again almost completely gone.
4th. I also used my receiver at home. JVC 5.1 channel receiver with RCA speakers and a Kenwood sub, didn't notice the issue at all. However there where some occasional strange popping noises when no music was playing I didn't get on my GS3 or other MP3 player.
5th. Finally I tried the ear buds that came with my Galaxy S3 and the distortion was again totally noticeable with and without music playing.
This is most definitely an issue that totally depends on what headphones you are using not sure if it has to do with sensitivity or impedance (this is what most people think) however it is most definitely an issue. I saw a few threads saying that audio issues were a problem in Android 4.4.2 however LG/Verizon have yet to release a stock base on anything but.
I suppose I could flash AOSP 4.4.4 and see if the problem persists but I don't know if that would even be worth it.
2 phones and 4 headsets later this is starting to seem like either a software or a design issue.
However I have nothing but good to say about every other bit of this phone. Really besides the audio jack top notch all around.

I might have found a workaround for this
I have tested 3 LG D855 and all of them have noise/static/high-freq leak from the processor out to the headphones. It might be a faulty design for the headphones amplification stage for headphones (when the headphones logo appears on the status bar). However, when using line level output (the jack appears on the status bar) the problem does not reproduce.
Therefore the workaround I've found is to trick the phone into line level output mode and then plug the headphones. To do this you need to plug in a 3.5mm jack extensor or a 2-to-1 3.5mm Y-adapter with no load, that's it, with nothing connected to it. At that moment, the phone will activate the line level output mode. Only after that you will connect the headphones, and you'll see there are no artifacts on the audio.
That being said, I'm not sure this will work with all kind of headphones as I have only tried with mines that are low-impedance ones, but on those it works perfectly. To be checked if the level of the signal in line mode is enough to drive other headphones.
In any case, it is a shame this happens with a high-end and expensive smartphone. I was hopping this will be fixed in a newer hardware revision but I got two replacements of mine and no luck. I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Ive been having the same issue. I have a pair of Shure SE846 which are about 8ohms. I experience the poor audio, especially the noise in the left channel. I find that placing a call and then listening to music removes the left channel static but the sound is still kinda bad. Ill try your suggestion tonight and post back. Just wanted to let you know your not alone.
I despise my G3 because of this. Im looking to get a new phone unless I can fix this.
Nope, my sound is perfect on my high-end Sony over the ear phones. Crystal clear on pure stock G3 .
I haven't noticed any artifact issues on my phone when using headphones, however when I plug it into my vehicle and also plug in the charger that causes everything to go nuts. The USB interference causes a crazy amount of excess noise. I haven't ever actually tried listening to headphones while charging, so in the car is the only time I've ever noticed it. The same issue occurs when I plug in my Galaxy Tab Pro into the aux jack and charge it at the same time, so this is definitely not unique to the G3. I wish all phones had as good an amplifier as my HTC DNA does, I still use that thing for music because the sound is so good.

I'm having a different audio problem.
With headphones plugged in and listening to music using any player, the right side sound emits distortion/hissing noise at a certain frequencies. When I tested it with plugging a 3.5mm to 3.5mm to an external amp (JDS labs c5) the distortion/hissing noise is completely gone. So it's definitely not a faulty jack
The hissing is evident at the beginning of (first few seconds) Tina Area's Still Running and You set fire to my heart .
I'm testing it with sensitive iem (Westone Um3x).
So does this mean there is a problem with the internal amp of the g3 or more to do with the os bug that can be solved with a custom kernel or update.
Is this a common issue found on all g3s?

I have read somewhere this might be a flaw in Snapdragon 801, as it integrates completely the signal routings but isolates badly highfreq noise from processor stages, etc. etc. but I do not remember where I did read it unfortunately.
I hope this helps!

Hi! This worked perfectly for me but for me instead of tricking the phone into line level output mode, I detaching one side of my headphones before plugging it into the headphone jack then reattached it afterwards. I'm using pair of sensitive iems (Westone um3x rc)
Everything is quit with no distortion, just how it should be!
One thing, is there an option within android or an app that can permanently enable line level mode ever time headphones are plugged in without having to trick it.
If so, I won't have to sent my phone for repair!
Also are there any disadvantages for using line level with headphones?

Using line out shouldn't make any difference on audio quality. It only disables the remote (buttons and microphone).
Would also really like a way to force the line-out mode. Btw, does this affect all G3s? Cause right now I'm not sure if it's worth the hassle of replacing it.

I know but some how using line out causes the hissing from the right side to go away completely. Strange huh
Are you also having this problem?
I also don't want to return mine if it exists in all g3s and there's a easier work around.
Yea same thing. I have artifacts in the left channel except when I manage to force the phone to recognize the headphones as line-out. I did this with the adapter to test it and it's impractical if not impossible to use the same adapter all the time.
I'm gonna try doing this right this moment to see if it works: http://forum.xda-developers.com/lg-g3/help/hissing-noise-left-ear-playing-music-t2804065/page17

I don't use earphones with a volume remote or microphone so that's not a problem.
It could be more to do with the increase in output impedance but I might be wrong cos the volume level is identical to headphone out.
I'm also getting a lot of static background noise but it disappears after making and hanging up a call as mentioned in a thread.
But yeah a permanent fix by forcing it into line out or doing some changes in kernel would be much more convenient

Great news! I just tried the fix from that thread and it worked. Here's the post: http://forum.xda-developers.com/showpost.php?p=59601465&postcount=150
I'm using stock rom which had 3 mixer xml files and I edited 2 of them, mixer_paths.xml and mixer_paths_qcwcn.xml. Also, instead of changing the value to 0, I deleted the entire line as it was suggested later in the thread.
The artifacts/noise in the left channel are gone!

But mine is stock on stock Lollipop via official update and with the hiss coming from the right side.
Please excuses my ignorance but I know nothing about accessing and editing a ROM.
How do I get into the rom and into the file called system/etc"?
Will this headset works with our device?
40$ for ANC headset seems cheap
https://www.gearbest.com/earbud-headphones/pp_636900.html
Any info..!
It works with RR ROM (I haven't tested with other ROMs), but it isn't recognized as a headset, so you can listen to music, but you can't use it for phone calls.
If anybody knows a workaround to get it to work, it would be great.
What about noice cancellation? Is it working? Thats what make this headset different..!
ANC is a functionality that is provided by the headset, not the phone. To answer your question, yes it works. I have no comparable headphones, but it works quite great when I use the bus or train.
I see some reviews saying ANC is working only from mi music app thats why I asked whether its working in our phone or not.
How are you turning on ANC from headset? Is there a key for that?
There is a little switch placed on the remote. When it's activated, a tiny blue led lights up.
ANC isn't restricted to an application. You can plug in the earphone, activate ANC and it works, without opening an app, or play music.
Good..Thank you..!

I'm thinking of buying one. Did it work out for you? I'm using Lineage OS also, have you tried on a custom ROM as well? Thanks!!!
I am thinking of getting one too but I want an assurance that it would work when I get it. Also, I read reviews online about the sound quality but am still quite sceptical about the sound. So if anyone has tested it out and tried few eq's on them such as Viper4Android, please your opinion would be very useful. Thank u.
I finally got one for my leeco le max 2!!!!! It's good but my equalizer (Viper4Android) doesn't work for it and that's a little disappointing. But with apps such as Poweramp you can get better sound quality. I can say the headphones sounds better than the stock cdla headphones and yes the anc(active noise cancellation) works!!!. Drains a little more battery but I guess it functions like cdla(I mean similar power consumption)... In my own review it's quite good.
Same problem here with viperfx, I think it's because the earphones aren't recognized as usb input. Randomly DolbyAtmos workes for me as an equalizer, but not all the time and I don't know what affects this.
V/S the leeco Cdla

Well audio clarity is most definitely obvious on the Xiaomi noise cancelling earbuds also durability in terms of the cable is quite good ANC(active noise cancellation is not as great as I hoped especially when compared to a different pair of ANC earbud i used to have in about the same price range) however the sound in general that is, the bass especially the bass, the mid and highs are ok on the cdla earphones, but durability is terrible. MY cdla earphones cord ripped to shreds that's how bad the cables are.
BAD NEWS: My Xiaomi earbuds fell on the floor and the left ear just died(only very faint sound could be heard) but the right ears were okay, so am not so sure of its durability. And I just recently got the earbuds
Hey, I'm not sure if anyone else is having this issue but when the dac isn't on, it's static during the music and when I'm in a call, there is static in calls on the left side. Does any one have a fix for this? I've had these headphones in my V20 and this is my first day with my V30+

Hi,
haha - and here I am and thought this phone was having hardware issues or something (does it ?) - perhaps it's just the headphones and they have an inherent flaw ?.
At least I'm getting the same weird behavior that at some points it plays fine but at others there's LOTs of (electric sounding) static on the left side.
It's actually never fully continuous for longer periods - it's more of a stuttery (multi-second) behavior for several seconds that this noise appears.
Also at first it was only via quad dac enabled - on AOSP Pie (internal LineageOS 16.0 build) it's existing no matter whether I play via Android Audio or Hi-Res Audio (USB Audio Player Pro).
And this exists on very low volume levels - there seems to be a connection that when the volume levels are raised (above 25/30% or so - I'm usually listening rather low but with this phone and hi-res - why not go higher ?)
it's way more salient and there also may be distortion involved:
An especially remarkable track in this regard is Thomas Bergersen's [from Two Steps From Hell] "Lost in Las Vegas" (around 08:30 or so towards the end, 10:14 long) towards the end - a rather electric part of the track and
when you raise the volume the output becomes rather distorted which might be connected to that "issue" and the left channel is also hissing/giving off static way more.
Perhaps audiophile folks and audio hardware experts have a better idea what this is hinting at ?
So:
not sure if it's an issue itself with the Xiaomi Hybrid Pro HD that they can't take that extra AMP (they are supposed to be low impedance and thus not require high output)
but somehow this behavior only occurs on the LG V30 - so perhaps there some kind of hardware issue ?
It seemed to have gotten better however from my impression with all those updates to the subsystems in the kernel - so it's perhaps just bad hardware design and the headphones are rather sensible
with their balanced armatures ?
Anyone else with balanced armature (BA) headphones observing a similar effect ?
I haven't had any trouble with my (dynamic driver) headphones. I wonder, have you messed around with forcing high impedance mode?

You mean high impedance adapters and such ?
Nope, only directly connecting the headphones.
And whereas before it only happened with the quad dac activated (which might provide more juice),
it now also seems to appear with the internal DAC used only (toggled via USB Audio Player Pro).
There might be a difference on how the internal and quad DAC interact or are active on recent Pie AOSP ROMs however ...
It still doesn't explain that weird behavior from the headphones themselves
Thx
I have tried it stock with no mods and it has static. Slide down the drop down and turn on the Dac and it goes away but only for music and system sounds. With calls it definitely makes noise all the time. I tried with a AOSP rom and it makes noise system wide because of the Dac. I did try my Phillips headphones and those work fine without the Dac on but I think it's a specific issue with these ear buds because I also have a 2nd pair and they also make the same noise.

yeah, the Xiaomi Hybrid Pro HD are the only headphones so far that show this kind of "behavior" with the LG V30,
not sure what is up with that.
