Solution to the hissing sound on G3

I am using sony XBA-H3 , which has two kind of lines
one is with mic, four channel plug. Another is without mic, three channel plug
this solution is just for three channel plug headphones
Everything you need to do is play your music first, and then plug in your headphone which has three channel plug
the phone will detect as audio out put bet headphone(look at the small icon on the notification bar)
and then, you will find that
AMAZINGLY, THE HISSING SOUND DISAPPEARED
So, i think the issue might come from some audio process for headphone only?
But, at least, we finally got a way to listen to music on our G3
edit
you need to plug your headphone very slowly that it could be identified as audio out put

ZTE Blade A475 and maybe others, low headphone aux output volume Fix

Hi, I have recently bought a Zte blade a475 and everything is fine except for one thing and that thing is the very very low volume coming from the output jack when you connect an external device like a car stereo for example, but if i connect the headset everything is fine so i knew something weird was happening there so i decided to find out the problem.
when i connect the phone to an external speaker and press play in the music app i can hear a weird sound like a "plop" just before the music starts and then the volume goes down to almost 0, but when i connect the headset (headphones and mic) everything its fine and no "plop" sound so i realize that must be a software problem.
Also if you connect the aux cable just the half of the connector it detects the cable as a headset then insert the connector all the way down and everything plays just fine with no "plop" sound before the music starts but is annoying to do that all the time so heres the solution.
FIX:
This may work in other zte or chinese phones.
1.- Go to enginer mode: to do that dial *#*#3646633#*#* then go to hardware testing, select audio, select Headset Mode
In type go to media and Set the Max Vol. 0~160 to 104 and set
thats all !!!
Tell me if it works for you

Thanks Heaps
My A475 is doing this same thing when my volume is set at full, this fixed the problem.
If you're interested in a ported TWRP for the A475 MT6735P variety, theirs one on needrom.com

Bose QC25 headphones

I have Bose QuietComfort 25 wired headphones. Anyone else use them and have problems?
1. As soon as I plug them in to the phone and adapter, the ring volume immediately goes to vibrate.
2. The in-line microphone is not working.
3. The in-line buttons seem to provide random results on the phone, usually any button just ends up lowering the media volume.
4. After plugging in the head phones, the power button no longer turns off the screen until i press volume up and volume down on the phone.... ?????
Audio through headphones works just fine though.

Not tried them with this phone myself. Sounds like a pinout issue, like you would need a CTIA/ OMTP adaptor. Although after trying to look to see which it is, I'm seeing lots of places selling an official BOSE android compatible cable. So I guess getting a new cable, while not great, is your best option.

Try shutting down, plugging in the headphones and restarting.

Use USB-C Headphones?

I got my Mate 9 Pro wet on a run a few weeks ago, I dried it out pretty well, however every time I plug headphones in now, it screws up a bit, thinks headphones are still plugged in, this lasts for a few days then returns to normal!
Of course while it thinks headphones are still plugged in it sends all audio to the headphone socket, so calls etc have no sound. (I've installed SoundAbout which is pretty good, I can enable and disable sound to the headphone socket with a widget button.)
I'd rather avoid doing this and simply switch to USB-C headphones.
I bought a USB-C headphone adapter, but the phone doesn't recognise it.
Any ideas how I can get the phone to send audio to a USB-C headphone adapter? SoundAbout has an option that says it send audio to the USB, but it doesn't!
