[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.

Poor bluetooth audio quality

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

Bad bluetooth audio quality when not using aptX (HD)

Hi there,
has anyone else quality issues with bluetooth audio? When not using aptX or aptX HD, music sounds like it only had a bitrate of 64kbps. Really bad. Tested this with two car stereos and a bluetooth speaker. However when listening to music with an aptX (HD) enabled device, it sounds perfectly fine. With my old LG G4 I didn't have these problems using the same devices.
I also tried changing bluetooth settings in developer options, but that didn't change anything.
I'm currently on TW 1.24.709.7
Greetings

Fix for Audio Issues - Bluetooth speakers & headphones - distorted sound / no bass

Fix for Audio Issues - Bluetooth speakers & headphones - distorted sound / no bass
A little background - this is an issued I've had since my OP6, and includes the OP7 and OP8. On my past 3 OP phones, I had an issue where most Bluetooth headphones and speakers would sound good initially, but would eventually sound terrible. The issue for me would be bass would be non-existent. Nothing was changed as far as the built in audio controls (Atmos and the EQ). Nothing short of a factory reset would solve the problem. I have one pair of Bluetooth headphones (cheap Otium beats knockoffs from Amazon) that never had this issue, but every other pair of headphones and Bluetooth speakers would.
This is a common problem as seen on the official OP forums. Some people claim making a call would solve the issue - it didn't for me.
What did solve the issue was ViPER4Android (https://forum.xda-developers.com/showthread.php?t=2191223) I'm not sure what the issue is with the built in audio drivers and controls, but the OP software has long-running issues. Viper solves these issues perfectly. I would recommend turning Atmos settings to None, and resetting the EQ to flat and letting Viper handle the enhancements.
Of course, this requires root, but it seems to be the only solution to this issue.
