Can anyone try A2DP?

I was wondering if the audio quality and sound stuttering has improved by using BT stereo headphones with Blackstone...
I have a trinity and i still haven't found a setting nor a rom nor a BT stack which handles my samsung headphones with a decent quality and no stuttering...
My cheap nokia 6234 has a solid connection and a good quality sound compared to the trinity... Plus, the A2DP connection slows my device down so much you have to pause if you want to do anything with it...
So if anyone could report about using bluetooth headphones with Blackstone, I would be very grateful as that would help me decide whether to buy or not
Thanks a lot

Great
I have the Touch HD for a few days now with the BH S100 HTC bluetooth headset. I have to say that the sound quality is great. It is even better than my conventional mp3 player.
Stable, never lost connection, etc.
Hope this helps.

I tried it today, with my Sony-headset.
It seems to stutter, though, for the five minutes I tested.

I have the Blackstone from seven day and the A2DP is OK with my Sony_Ericsson HBH-DS200.
The sound is very good and the pairing with the phone is immediatly in about 1 second.
Regards

reasonably OK with my Jabra BT620s. However, quality in BT A2DP is not really comparable with wired headsets, and i got some losses when passing nearby EM sources like wifi, etc.etc.

I needed to enhance the quality with Schaps Advanced Config Tool.

Alpine radio
I have an Alpine radio with bluetooth capabilities in my car, and for the first time I have a great connection with my HD. My Touch Diamond stuttered.

Thanks a lot everyone!
I guess it depends by the headset model and interferences then...
I'm still looking for a shop which would make me play with it for a little while...

i have a pioneer deh 700bt and the headunit set up was easier than the nokia n95
streaming music was a bit weird, the quality was very weird, kinda like very low bit rate streaming on mp3s at times, then fine again.
my n95 music used to pause when i took the key out of the ingnition and the stereo turn off
however the HD just keeps playing, but not through the speaker phone....just see it still playing
bit disappointed, and looking for a fix
I've only played for 10 mins, so i'll let you know if i find some more.

I have an Audi A3 from 2005 with a original BT carkit.
Can I use my HD to play some music ?
I can make phonecalls without a problem, if I adjust the volume of my carradio the volume from the HD is also adjusted.
But is there a possibility to play some music ?

Has anyone tried the Plantronics 855 Voyager stereo headset yet?
Also, I'm currently using the Jawbone 1 and noticed horrible interference/noise in the ear piece when the wifi is on, anyone else experience this?

I've never had any problems with the diamond and now with the hd. Like the senior man said, you need to increase the bluetooth bitpool values either in the registry or by using schaps tool. The difference in quality is immense - low values will make high bitrate music sound 64 kbps so you need to change this. Of course, the higher the bitpool the more chance of dropouts but I run at 60 and rarely, if ever have any dropouts.

Sennheiser MM200
Now if tested for almost one day my HD with my new Sennheiser MM 200. Amazing!!! The use of the MP3-Player switched with the use of the remote control to a new level. During sport display can be switched off(no need for touch display-less power consumption (try to give a more compareable info in future)), full control of play/pause/fwd/rwd/volume function. There is no delay of the HD in using the remote nor any transmission interruptings. Now the HD is with armwrest a perfect sport companion. The sound of the earphones - haven't had any better sound (and i've tried a lot of earplugs). Neckstrap fits perfect, mic in perfect position, clear speech and due to perfect noise reduction of the plugs even in noisy areas perfect understanding.
The Sennheiser was just charged the first time - i'll report the stamina.
So far -

I am using the i.Tech S35 bluetooth clip also on my HD now, and sound is very good, with WiFi on. Advantage of the clip is that one can use any headphones with it.

It's not possible to play music, only phone functions are available.
I've tested the HD with the PARROT MK6000 and everything works very fine, also A2DP, Quality is good.Phone Functions great, Phonebook synchronize works perfect

Vibrant Sound Out + Car Aux In

Hi guys, my 328i has a built in Aux input. And it works great with my Vibrants 3.5 output jack. The only issue I have is, the volume is just not as loud as It is listening from the mp3 CD. The volume for both the phone and car is at full volume.
When I usually listen to mp3 cds, the sound goes up way louder. Is there a way to hack the phone to output louder through the 3.5 jack? Or if any of you have the 328, is there some option to do that?

I don't know about mp3 cds but as for official cds bought from the store, they are definitely a lot louder that the phone through aux jack. Same deal with my g1 before I got the vibrant.I'm sure once the rooting and custom recovery is all sorted out and we start getting some custom roms, the devs will include volume hacks just like they did for the g1.

I'm quite satisfied with the volume. If you need to blow your ears off boost up the EQ.

Actually, it's really weird. Through headphones I can equalize my Vibrant and iPod to sound the same, but through AUX, the vibrant is quieter (Same volume settings). Really makes no sense to me. It has to be something with the equalizer...
Edit: But it is in no way quiet. I have to turn up my car stereo by like 4.

Try a different cable or a higher quality audio file.
I play songs between 192kbps to 328kbps and have no problems. The volume is at the same level since I used my mp3 cd.

appreciate the inputs, i'll look for the equalizer on the phone.

Have you guys tried sending the audio thru bluetooth audio enable car radio? Pretty cool no cables needed
I can even listen to pandora and send the audio to my stereo

whoa, i'm going to have to try this out. any advice?

I have the Pioneer Z110BT Navigation and it has bluetooth audio. Just pair your Vibrant to the Pioneer then play any song on your vibrant using the music player. Click options then "Via bluetooth".
Then go to your stereo and click on bluetooth audio. Voila! Streaming music from your Vibrant to car stereo. The sound is also great!!

Not to hijack this thread but my one complaint of the phone is how low call volume and audio volume are.
Everythings turned up to max and this phone is roughly half as loud as my MT3G is set at 50%.

I have a Sony xplode and play through Bluetooth, I get great sound.
I have no issues with call sound or ring levels. I actually have to turn it down sometimes because its to loud.

I built a custom cable to connect the headphone jack to my Pioneer's IPBUS connector - it works great, and is very loud. I keep both the head unit and phone's volume on half way, and depending on the song I may have to turn it down, too.

Bluetooth "Enhanced Stereo" Low Volume Issue

I purchased the new Moto S10's and I've noticed that if Enhanced Stereo is checked the audio quality goes way up, but the volume level is very low. When I turn it off, it allows the volume to go to a level I like, but the music sounds like im streaming from a low quality source. Is there any way to raise the volume of the enhanced audio setting? Any root setting values I can tweak? Thanks!

I use Enhanced Stereo on my 2010 Prius and it works perfectly. (Did on 2.1 and still on 2.2.) Sound quality is wired quality and it's super loud. (In fact a bit too loud -- not distorted at all, but louder than other sources on my stereo.)
On the Prius forum several Android users are complaining because the Galaxy S does not have this feature and BT-Audio sounds like crap.
I've also paired my phone to my Logitech STR-01 BT-Audio streaming receiver (a woot purchase) and it works perfectly there too.
So I would conclude the problem is with your paired device.

getting very bad bluetooth audio quality

iam having the worst ever audio quality over bluetooth while listening to songs...whenever there's treble it sounds like a worst radio quality..iam using sony ericsson MW600 bluetooth stereo headset..does someone have a solution for this? or is this universal problem?

That sounds like it's using the hands free profile instead of A2DP. You could try going to the options of your bluetooth headset on and untick the "Phone" box, and make sure "Media" is ticked.

I have generally decent bluetooth audio using Motorola T505 to broadcast FM to the car radio (must get around to buying a proper BT head unit, or a new car with one built in...). Most of the problems I have are interference with the FM signal rather than dodgy bluetooth.
However, I do see this kind of bad distortion on the high end with certain pieces of music - generally the solution is to turn down the volume on the Note a couple of notches and crank it up on the car stereo. I assume some of my tunes are just recorded/ripped REALLY DAMNED LOUD, it seems to mainly be things I ripped myself years ago so I probably didn't pay much attention to the levels at the time.
If you lower the volume from the Note does the distortion disappear?

No, still there. I'm using Galaxy note and noticed a similar problem, both with a pair of Plantronics BackBeat and bluetooth car kit FM transmitter. It sounds pretty fine on my Archos 5IT that is running Android 1.6 and my Nokia N900 running Maemo. My note is currently running on Android 2.3.6 Rocket 12.

Bluetooth stereo sounds great for me using Sennheiser MM-200...

If you have exceptionally bad audio quality, it's probable that the headset is being used in handsfree audio mode, and not media mode. If you go to settings>bluetooth, and click on your device, you should see which modes are ticked.
Also, some people have reported better bluetooth audio quality with the LR1 modem. See here:

Bluetooth Music Quality

How the does bluetooth sound for you guys? Mine seems to be worse after the B29 update (not for certain that's when it degraded). I have a decent car stereo setup, but bluetooth distorts and crackles in the mids and highs. It's not unlistenable, but I thought my stereo was on the fritz until I used my 3.5mm input from the headphone jack, which sounds just fine. It can't be that the DAC is that much better, as my other phones sounds fine and this used to.
Do you have any thoughts or experience with something besides a small bluetooth speaker?

And I have tried playing with the Dolby settings. They make no difference with the distortion.

After some perfunctory tests I have noted that Bluetooth audio seems to introduce a significant amount of extra noise at high volumes. Aside from the additional background noise I have not noticed distortions with Bluetooth yet. I have only checked this on B29.

Just something to try...I have a BT device hooked to my AVR, and when I stream through that, if I have the volume on my phone up it sounds horrible. If I stream through it with the volume up just 1 click of the volume button, it sounds good. I increase volume at the AVR instead of the phone.

Through Bluetooth hands free working flawlessly to my.(A2017G version)
I'm having 2 LG 1100/2 Sony SBH 80 and 2 SBH 20.
Haven't try it with external speakers(since I don't own any kind) and on my car I'm using the handsfree and not connected to the car audio system.

I have a A2017G on B05 and a somewhat cheap aukey BT headset: it seems to sound fine for me, no crackling or hissing. Have you tried it on different devices to compare?

A2017U on B29, using Jaybirds Bluebuds X, the sound its great, no distortion or cracking.
I use the Bluetooth on my car stereo too and the sound is excellent. No dolby, but the equalizer works fine.

Did you verify that all your bluetooth devices supports aptx? if not then you will lose sound quality :S
idk, i dont like bluetooth audio streaming... even with aptx. Its not bad but if you want to steam flac music it will still limit the quality. Somehow if i stream the music via bluetooths aptx it sound flat not dynmic and
voluminous.

I haven't tried it with the volume just below full. I'll give it a shot in the morning on my commute.
Other devices (S5 and 6P) sound just fine when paired to my headed unit, so it's likely something with my Axon 7.
-----
Quick test with the volume just under full seemed better. I'll know more after a drive tomorrow. Thanks everyone.

EQ on on your car stereo or phone? I don't know of an EQ on the phone (maybe I've overlooked something).

On the phone. I meant to say that it's not using the HiFi audio, but the Dolby eq it's fine on Bluetooth. Sorry for the confusion.

I think it sounds about 95% better just one click below full volume. I never would have thought that digital Bluetooth volume would have been the problem, having always set it to 100% with every other device. Thankfully, Tasker makes for a quick fix.
Thanks for the tips and feedback, everyone.
