[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

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.

Headphones with working previous/next/volume buttons

Are there any good in-ear headphones with working previous/next buttons to control next/previous track and volume in any music player?

Hi well I've been using the Altec Lansing BackBeat 903 Bluetooth Headset for about 3 months now and that has all the features your looking for plus they sound damn good as well.

I use the stock headphones with winamp, and double tap the pause button and it skips to the next track
But for a real solution with back.. you could get one of the little reciever thingies with a 3.5 jack, so you get wireless + controls + any headphone you like ^_^. But there could be some quality loss if its cheap..

Motorola's s9-HD also have theses foncions enabled.

Thanks for the replies. Those two seem to be ear-hugging types, are there any with regular design?

the best would be to use the Nokia remotes that came with the n95 and others. But apparently it doesn't work since the layout inside the jack are not the same between Samsung and Nokia... too bad

I have a question about this topic, I tried to use the apple in-ear headphones with the mic and the volume buttons on my SGS but when i fully plug it into the jack, theres no sound.... but if i leave it out abit then it works fine.... Do u guys know what is going on?

Any Bluetooth headset supporting A2DP (Advanced Audio Distribution Profile : For Stereo audio) and AVRCP (Audio/Video Remote Control Profile) should work. There are plenty of BT headsets out there. Search for A2DP Bluetooth headsets (if they have media player controls then the chances are they support AVRCP too).
I use a Bluetooth clip, it gives a certain amount of wireless freedom and the ability to use any 3.5mm headphone. If you already have a good pair of headphones you like then a BT clip is perhaps the best way to go.
Here is what I use (Motorola S605):
With a display (SonyEricsson WM600 ):
Both of them have a built in Stereo FM radio as well, if you listen to radio that could come in handy (since the radio on SGS is mono ).
EDIT: One last thing, Audio quality over Bluetooth is slightly lower compared to a wired connection. This is due to the compression codec used in Bluetooth transmission. However, the difference depends entirely on your expectation of sound quality and the quality of your audio files. For example if you are an average user who is happy with a pair of $25 head/earphones listening to MP3s encoded at 128kbps then you won't notice a difference. But if you are an audiophile having $100+ headphones listening to 256kbps+ encoded MP3s then you’ll definitely notice a difference.

Could you please tell me is this possible with bluetooth clips:
I connect wired headphones to SGS directly (not to the bluetooth clip 3.5mm hole), pair the bluetooth clip with SGS, start player and listen to music through headphones and have ability to start-stop player by bluetooth clip buttons. When the call comes I hear it in headphones and start-stop player or push call answer button on bluetooth clip. After pushing answer button I hear calling person's voice in headphones but talk to the bluetooth mic. After call is ended I can start-stop playing music again by bluetooth buttons. This is 100% tested or it's is appeared to be working? Thanks.

I don't think it works like that, but I have to check to confirm.

When you are not using BT audio, I doubt the player will respond to BT player controls.

I dont think you can split the mic and headset function like that, either you use the BT for both mic and headphone or not at all. (unless someone modifies the driver). But again, something I have to check to confirm.
For basic call and volume controls something like this might work.
Here is another alternative, but no mic (not released yet either).

Very helpful, purchasing from ebay as we speak, im sick of not being able to switch song whilst cycling...
Just a question really, do you just use the standard samsung music player?

I like these, thanks.
How does this things work? Do you plug anything to the usb port or do you just enable blutooth and play? Also can you use previous/next buttons while the screen is locked? Can you do these with the default player or do you need anything like WidgetLocker and add the player to the lock screen?
Also are there any wired versions of these?

Can WP7 stream hi quality music via Bluetooth?

With WP7 having Zune so heavily integrated, I would imagine that MS will have considered that some of us will want to play the music that we've downloaded with a Zune pass on some speakers, rather than headphones.
Clearly there are not going to be any speaker docks out there for WP7 phones as they're all slightly different shapes & sizes so what I want to do is get a bluetooth receiver to put into the aux input on my ipod speaker dock and stream music from my Omnia7 to the speaker dock using something like the Bluetooth wireless audio receiver from Belkin.
Is this possible? As the music downloaded with a Zune pass is DRM protected, I can't just copy it to my itunes/ipod etc so bluetooth would seem the best way.

I stream music from my HD7 to my Toyota's audio system via bluetooth, and it sounds absolutely fine to me.

Yes

Hi all
I use a HTC 7 Mozart with a Jabra SP700 which connects with both the HandsFree profile and the High Quality Audio Profile (A2DP).
I get very good sound quality via the device over A2DP.
Cheers

I have connected a Chordette Gem to my Hifi Rack and transfer music via Bluetooth from my WP7 (and Laptop etc)
High End D/A Converter inside (24bit and up to 196kHz), so you can expect audiophile sounds

The other thing is that you don't want to have the phone volume all the way up... Correct me if I am wrong, but you want to let your amplifier doing the amplification - not your phone. I put my phone on 20/30 and it seems to make a difference in my Ford. It will also not force me to turn my system all the way up in my car.

BT headphone or headset EQualizer

Hello all
So this is the problem. since I have tab 7" I use a headet a lot. But the audio in my headset is full of bass. It's like someone speaking to me true inside a deeeeep hole. just a lot of bass. So I was trying all kind of equalizers but non of them work on BT output. So question to all of you is there a app like that.
I am running overcome ROM 4.0.0. I tried voodoo app (works great on headphones and speakers but not on BT headset. Havent really test BT headphones A2DP since my battery is dead and I just can't find my cable.) I tried a lot of EQ apps from market but non of tham have effect on BT. I also tried that DSP manager but it does not work at all. I can change settings as much as I want but nothing actually happens.
I remember that old phones without any smart OS could do that. They had in call equalizer. Funny that such a smart OS like android doesn't have something like that.
So please help. I there is no such app someone should make it.
Thank you all

Sounds like the extra booming bass is a characteristic of your BT headset as the Galaxy tab is not the source. The Tab has one of the best audio chips. Did you try with another BT headset? If you tell us which brand headset you use you may get more feedback...

It could be. Headphone is SE HBH-608 and headset is nokia BH-503 but this Nokia is not tested since I lost my charging cable. Can't find it. After I test it I will know for sure. But it could be that is because of headphone.

hi. thanks for suggestion. I tried that one and all other EQs. Non of them have effect on BT sound output. It does on a2dp BT output but that is only for listening to audio. Voice does not go via a2dp so it can't be modulated.

That's funny. I have used all EQ's with success through BT going to my BOSE Soundlink speakers.

No problem wit my BT platronics

volume+
try volume+ by meltus. it works bluetooth with my prius. it has bluetooth settings.

It was probably because of headphone. I tried headset and it is better but it also depends on other side and persons mic.

I think it is from the headset, because I had that problem earlier when I was using SE headset (I don't remember its model), but when I use SE MW600 the sound is so clear, btw if you have A2DP bt headset with 3.5 audio jack you can get different quality of sound if you only change the wired headset attached to it.

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.
