Poor bluetooth audio quality - Nexus 5 Q&A, Help & Troubleshooting

When I'm paring my nexus with a2dp devices like headphones (bt620s) or car stereo (kia ceed 2015) sound quality is bad like I'm playing 32kbps mp3.
I've tryed to connect wife's iphone and it sounds great with no artifacts. Same with surface pro 2- no problems. Looks like google miss with bluetooth. I didnt find any solution on 4.4.4 or cm13.
I heard that change audio.a2dp.default could help but there is no versions for 5 or 6 android

Bluetooth headset.

What bluetooth headsets will work with the touch diamond?
other question: why should there be any headsets not working?
i have a really cheap but nice looking samsung headset, no problem to get paired with the diamond. should work with any other headset, too!?
My existing is just a cheap iTouch bluetooth headset and it works perfectly.
I don't think Diamond has any problem to work with other brands.
I have an old Motorola Bluetooth headset (4 Years) and it will not pair with my Diamond. Looks like its time to upgrade to a Jawbone!! hehehe
i have the jabra bt3030
its a stereo bluetooth headset working on A2DP
works great and looks awesome!!
So can I listen to music through any bluetooth headset (that has headsets to play music)?
My Plantronics P590 works like a charm

Say something about the sound, it is better (or/and louder) then original HS or same quality?
Here you go!

Theres a app called btAudio (keep a google-eye open for newer versions) that does exactly this, it will send ALL sound to the headset, despite of what windows had in mind for the sound (as in if it was gonna use headset or build-in speaker)
Tho, it sometimes chokes when you dont shut down the app before you disable the bluetooth headset or phones bluetooth function, but i guess that kinda makes sense (its even sayd in the program to not do that, but im a sucker for trying such things hehe)
And another thing, this happend for me too (taken from comments on some site, linked below)
The program runs well however if you try to make a phone call with the blue tooth ear piece while the program is active the program is not available after the call is completed.
I had to reset my phone to enable the program again. - source of comment
Guess thats related to windows not being to happy theres multiple apps using the headset, lets hope for a next version which auto-disables when calling and re-enables when u hang up.
I'm waiting for this one (Jabra BT530, due end August according to Play.com)...

Got the manual that Jabra put up on their support site for a day or two before taking it off. Manual says it also supports A2DP and can stream music.
And what about battery life? Could somebody using bluetooth stereos write how long the Diamond can last, and what is the overall impact on battery life while listening to music?
I use this headset, its got very good sound and is also nice and comfortable, since i have my tragus peirced i cant wear "normal" headphones!
http://www.amazon.co.uk/Sony-DRBT20...6?ie=UTF8&s=electronics&qid=1216998998&sr=8-6
It also works on my pc and my PS3 as a wireless headset/mic!
I have proper enclosed stereo headphones Dell DH-200 with volume control, next and previous track plus play/pause buttons and it all works fine with HTC DT. The only think I am not sure about is which profile it is using, the sound is not as good as when I have it paired with my laptop, which would suggest a low speed profile as opposed to HQ.
You can change the bluetooth profile in Schap's Advanced Config. I've set bitpool to 70, max to 76 and min to 64. Now the sound quality is waaay better.
I can't connect my Jabra 320's (worked with SE W880i) to BT Stereo, it only see's the headphones as a handsfree unit on the HTC
Jawbone. Nothing else comes close (for hands free anyway!). And the new one even matches the Diamond... sort of!
Has anyone suffered the sound periodically dropping out for a second or two, mainly during the first minutes of connection but still persisting now and again several tracks down the playlist?

[Q] A2DP quality

Hi! I'm interested in buying the Desire Z, but I'm not familiar with the sound quality on A2DP headphones on Android. On WM there are settings like bitpool in the registry that can change the quality a lot, but as far as I read, there are no such settings on Android and the quality is really bad.
Is it true or is there a way to change some settings to improve quality? This is really important to me and I don't think I would be buying a phone that can't play my music properly.
My htc hero and car stereo utilizes A2DP perfectly, streaming audio to car speakers. Have not noticed any bad quality, not åk expert though
Sent from my HTC Hero using XDA App
Thank you for your reply, I'm hoping that I will be able to hear it myself sometime soon and see how it sounds.
Btw, have you had any disconnects and things like that?
I tested my jabra BT320s on a desire I have access to and the A2DP was spot on, it used the handsfree function aswell without issue pausing the music then carrying on after the call etc...
Am impressed, this was with stock tmobile UK firmware aswell.
Only personal experience
I have to say that when compared to Nokia N900 the a2dp sound quality doesn't seem to be as good. The music sounds somehow thinner. To make these comparisons I have used the same media files, same nokia bh-214 handsfree and same sennheiser mx550 headphones.
I hope it is possible to somehow tweak the a2dp sound quality since i think it's all a question of a2dp audio quality settings.
It has the be said though that in contrast to nokias bluetooth implementation the android one does handle switching from music to phone calls and back quite flawlessly.

[Q] Bluetooth A2DP bad sound quality

Everyday when I drive to work I use my phone to stream music to my radio over bluetooth. Now when I tried it with my new Moto G I have problem with sound quality. The sound is somewhat distorted, metal sounding with plenty of compression artifacts. I tried to reconnect the phone, unpair and pair it again. I even tried different players and disabled all equalizer effects without any success. My previous phone Huawei G300 with ICS was plaing music flawlessly. Now when I connected phone to my PC over the bluetooth the sound was just fine. Anybody else experienced this problem? Is there any way to fix it? I searched the web and it seems that many users had smilar issue with A2DP running different versions of Jellybean.
No problems with a2dp here on 2 different receiver devices, so sorry. Running the MG with 4.3
Damn, so it has to be some compatibility issue with my car radio and this phone. Too bad Will try to resolve it somehow. Thanks.
Maybe the Moto G also have a low bitpol (bitrate) value for the SBC codec? When used with a compatible BT receiver that accepts MP3, it will sound fine whereas transcoding a loosy format to SBC at a even lower bitrate will cause audible audio artefacts.
I'm thinking of getting these small 30 pin Apple/iPod dock BT receiver which I suspect may only implement the bare minimum of A2DP : SBC codec, so if the Moto G is plagued by the low bitpol setting then I'll forget this idea lol

[Q] Bluetooth Audio Quality

Question Bluetooth Audio Quality
Does anyone have experience with how the audio sounds when connected via bluetooth? Is it as good as coming from the phone speakers? does the software allow to equalize the output? looking for a phone just for my car that works good with bluetooth, does not cost that much and has equalizing software built in... My personal phone now is a Note 5 but damn SoundAlive+ crashes when using Google Play Music and turning off the equalization sounds horrible...

BT good for me. Viper4android Works great for eq.
Bluetooth is fine. Its HQ SBC. No Apt-X support. Only EQ available is the terrible JBL "enhancement". Luckily it can be turned off.

Miserable Bluetooth Audio Quality

Hello,
I have a relatively severe issue with the Bluetooth audio quality on my phone. It sounds pretty much exactly like 64kbits MP3, you can especially hear it in the high frequencies. It's somehow distorted and unclear and extremely annoying as it ruins the experience totally. Everyone who heard sound over my Bluetooth devices has heard this.
The weird thing: I experienced this with both my Galaxy S5 (G900F) and my Galaxy S6 (G920F) and every single Bluetooth device that is connected to them. I tried it with my Logitech Bluetooth Audio Adapter, Denon AVR X1100W, Logitech Boombox and my car stereo Kennwood KDC-BT35U. The audio quality is always the same.
However, with my Nexus 5, my Galaxy Tab S8.4 and my Laptop, the audio quality over Bluetooth is great! Also, if I use the headphone jack on my Galaxys, it sounds just fine. I mostly use Spotify and Google Play Music, but the problem is not there since it sounds great when using a cord.
I asked the Samsung Support about this and of course they didn't know anything. They offered replacing the device but I don't think that this makes a difference since I had the same problem on my Galaxy.
Now I am asking everyone else who has the Galaxy S5 or S6, have you experienced something like this? Any solutions? It is very frustrating.
I just solved this mystery. For a long time I have been using the Mi Fitness Band, and I was wearing it all the time, so whenever that is connected to the phone the audio quality gets very bad. At least I know what it is now!
Same here!
If my Mi Band 2 is paired in the Mi Fit app, the audio quality of ANY connected bluetooth device (aux speaker, car audio etc.) is distorted (especially high sounds)
I reinsatlled the Mi Fit app, even reseted the whole phone, nothing changes. Only if I unpair the Mi Band in the mi fit app, is the bluetooth audio quality ok.
Samsung Galaxy S6 Android 6.0.1
Xiaomi Mi Band 2 firmware V1.0.1.34
Good audio quality at Bluetooth playback
Guys,
I experienced the same when i playback via Bluetooth in my car. Since i installed Poweramp beta, you can choose some different type of audio playback quality. I set mine at 24 bit playback, 192 khz. I can hear some slight difference but i think you can not expect much of it.
Second option might be Viper4android and Dolby Atmos. These will increase earsgasm at your desire.
Give it a try and report feedback!
Here is a screenshot of it.
Poweramp has unbelivable awesome effects, but it does not eliminate the base problem: miband (or any Bluetooth LE stuff?) affects the bluetooth audio transmission.

That is true and sadly a known problem of android in general. See http://www.androidauthority.com/android-wear-ruining-bluetooth-speaker-headset-sound-656300/
Solution
I might have a solution for some of you. Good luck.
Find it in my reddit post. I can't post URL's because i am new here. I only created this account for sharing the solution.
