[Q] Xperia and iPone 4 headset. Problem

I apologize for my English. Translated from Google.
Tell me how to solve small problem. The essence is as follows:
Presented with a headset on the iPhone 4, while listening to music and watching videos, sound is muffled. If you press and hold (!), The Play button on the headset the sound is normal. In another Nexus One, and he has them working properly. In what may be the problem? How to decide? Interestingly, once already tested the sound quality of these headphones, and it was not.

It's the way it is made.
iPhone is not built the same way the x10 headphone jack is
But I had included, works fine.
Maybe you didn't read what I posted.
Simple answer for the issue. Sony does things their way, while everyone else caters to the iPhone industry.
Headphones w/ mics have a male plug have 4 pins.....both Sony and iPhone, the first 2 pins are the same, but the 2nd two are different.
Pressing the answer button on the headset connects rings 3 & 4 on both headsets. (Which, in effect is the same as a listening only headset.)
Either use headphones without a mic (for music) or use a bluetooth headset (for phone) or use the Sony headset that came with the phone or visit the Sony store.

I read your message. And I can not understand why, then, to work? May be the case even in the firmware? Now is not the official 2.2.1
I heard that it happens only on headphones with mic, so I just taped the answer button on controller and they work fine You can also try some adapters from ebay or some similar pages...

[Q] Sound from one earpiece using headphone jack, common issue?

Hello,
I don't have a SGS3 but thinking of getting one. I've done some research and found a few threads mentioning an issue with the headphone jack.
They seem to get only sound from one earpiece if they use non-stock headphones.
Just wondering if this was an issue on the earlier batches or does it still exist? Here's one of the sites I found the issue being mentioned. Seems like I can't post a link yet so here's a quote.
Hi Seber Tech Team,
I am having the following 2 concerns with my Samsung Galaxy S3 I was hoping you could help.
First, when I plug in a headphone, only 1 speaker works. I have tested that headphone on other phones and it works fine. When I plug in auxiliary cable I only get sound out of 1 speaker, however, if I slightly pull the auxiliary plug out of the other end connection then I can get it to play in both speakers. I’m not sure why this is.
Second, the voice to text feature is inconsistent in that sometimes it works and sometimes it doesn’t and gives a message that it can’t connect with Google at the moment. I do have the setting set to download offline speech recognition but I still have this happen periodically and about half the time I use it
Thanks and any help would be greatly appreciated

The Galaxy S3 has the typical 3.5mm headphone jack with four sections. This problem seldom happens when you’re using the original Samsung headphones/headsets. When you’re using just any 3.5mm headphones, there is a possibility audio pins cannot touch the right headphone contacts. That is why you have to pull the plug out a bit to produce a stereo (left and right) audio. I photoshopped a picture below just to give you a clearer explanation why using typical 3.5mm jacks may often lead to audio problems in Galaxy S3.

Never heard of such things.
The 3.5 mm Jack is universal.
Only different is hands free and volume control may require particular headphones, but sound out is all the same to all 3.5 mm standard headphones
I am working in a mobile accessories shop, as far as I know.
There is type hands free earphones can be used on both iPhone and other Android phones (Samsung, HTC, LG
..etc )
And another type, capable of volume control, this type can only used on some specific devices, in this case Galaxy S3,Note 2, iPhone 4,5 etc

V10 as external DAC

When I bought this phone, I loved that it came with a 32 bit Hi-Fi DAC. I'm a sound engineer, an audiophile, a music enthusiast, and we all know this is quite a unique phone when it comes to music. At times I can be an "on-the-go" type person. I like to produce music everywhere I go. So I was wondering if there was some way to use this phone as an external DAC for a laptop? I don't want to invest in a DAC when I have the V10. My theory on how this setup would go is having the V10 and laptop connected through USB and having all the audio from the laptop go through the V10 and out the V10 audio jack. Is there some way to do this? I'm guessing this would have something to do with the kernel of the phone too. Any help is appreciated!

Headphone jack Loudness

every galaxy s model is always an excellent phone, but every year i have the same complaint with the headphone loudness. The headphones that come with it are great and i know they could handle more power. Anyone tried any non root way to increase the sound?
you need it louder? I have mine down one to two clicks from the bottom and it's almost too loud for me sometimes. I am around loud cars and trucks all day (I own both) but I guess my hearing is better than I thought lol.
unless you want a stronger sound and more power to the headphones for a cleaner richer sound, you'll need an external dac for that. I've never seen a phone capable of coming close to an external DAC (just look at their size, they wouldn't fit in a phone and be realistic.)

V30 USB Audio In Car

Hello all,
So I'm going through an "audio quality" phase and I've bought a bunch of crap to make music sound better. I bought a T-Mobile V30 off of craigslist for $130 today, and I am planning on using it as an audio playback device in my car, and pretty much just keep it in my glove box. I have a BMW M5 with a Bang and Olufsen sound system (sounds is incredible) and I usually use my iPhone 11 to either stream via bluetooth or stream via USB using Amazon Music HD. I read fantastic things about this phone (tried to root it and just gave up lol) and I didn't expect streaming via USB cable would be such a hassle.
As I mentioned, streaming on an iPhone 11 via lighting USB cable works great, I am able to control the music using the steering wheel instead of fiddling with the phone itself.
Any suggestions of how to stream via USB to your car with the LG V30? I've done some searching around and it's just people arguing LOL. Again, I'm just trying to keep my steering wheel controls while enjoying high fidelity music
Thank you all in advance!
What makes the V30 a great music source is its high-end ESS Sabre DAC, used when you plug headphones into the 3.5mm port and enable Quad DAC in settings. It is superb, and can drive all but the most demanding headphones.
It can drive external speakers as well through a receiver or amp, but often sounds a bit thin in such setups. It really was made for headphones/IEMs.
When playing through USB, you're sending digital audio out of the phone, relying on an external DAC (in this case your car's audio system) and not using the ESS DAC. I've tried to do this in my Mazda with Bose audio, but not been able to make it work. I know iPhones work doing the same.
Bluetooth works (controlled from steering wheel) but will be lower quality than USB.
I think most high-end car audio systems were designed with the thinking that only poor people use Androids, so no need to bother with them. The marketing people who make these decisions are generally not the sharpest knives in the shed, you know :cyclops:
I appreciate the thorough response! Yeah I’ve only read good things about the phone, I have hd650s that sound meh because of the impedance but might get a portable external amp for the phone. Also this LG off of a 5ghz /connection downloaded 110gb of music 10x faster than my iPhone 11. I stayed up till 4am trying to root it, I’m not going to give up on the USB playback, I’m an optimist like that LOL
And talk about marketing, ironically amazon music partnered up with BMW and the car and app both give you a notification that it’s fully supported. I have nothing but time these days, if I find anything different I will update the thread.
Thanks again The Dannemand!

Yes, please, I'll be very interested to hear if you succeed in playing USB audio through your BMW's audio system (nice car BTW )
First thing you want is probably get UAPP from the play store, if you haven't already. It's $8 you can't afford to save. It is both excellent at playing through external USB DACs (what it was made for originally) but also has dedicated support for the Quad DAC, maximizing quality through the 3.5mm port. It is one of only two apps that avoid molesting 16/44 music (CD quality), the other being Neutron. PowerAmp, while popular with many, CAN do it too, but only if you continually tweak its settings to match the exact sample rate of each track you're playing. At least last I checked.
Amazon Music HD does NOT work with our LG phones. It re-samples everything to 48KHz -- although it does a better job of it than the Android Mixer. But that won't matter in your case if Amazon Music can send music unmolested through USB. I don't know that.
As for the HD650, I never tried them myself, although several members comment on their use with V30 in the head-fi V30 thread. If you haven't already, make sure you also check the head-fi V30 Music apps, tricks and tips thread.
With ~100dB sensitivity the HD650 SHOULD theoretically be OK with V30. At 300 Ohm they will trigger High Impedance Mode (of course) with a max output of 2Vrms. They should definitely play loud enough. But maybe the low end gets a bit thin, depending on your preference and type of music. The ESS Sabre DAC used by LG is on the bright and analytical side, definitely not a bass head kind of DAC. An external headphone amp will help, for sure, although you may be better off then with a combined DAC/amp in that case.
Sorry for the lengthy post. I should get on with my work
Edit: To clarify, if my phone's USB mode is set to File Transfer, I can of course play files stored on its internal storage through my car's audio system -- and control it through the steering wheel buttons -- because it is simply using the phone as if it were a USB flash drive. But I don't think that's what you were looking for, since it won't support streaming.
