Improve A2DP quality? - Vibrant General

I can switch back and forth between my SGS and the wife's myTouch on my Kenwood head unit, while the myTouch sounds excellent the SGS is missing the lows and has scratchy highs.
Apparently there was an update for the Korean SGS for improved A2DP sound quality :

Anyone else notice, know of a tweak/fix, or maybe how to get the mentioned update?

My vibrant works with my Bluetooth head unit much better than my mytouch did. It does tweak out if the handset it set to max volume but 1 or 2 notches below and its crystal clear. And finally I can listen to music via Bluetooth without having to turn of WiFi like on every HTC device ever made.

Adjusting the BT volume makes no difference for me in terms of audio quality. Anyone else have this issue or is it just the combo of my Kenwood BT unit and this phone?

Bluetooth Audio Quality

(Update: 2/23/10: To replicate the problem, use a bluetooth headset, make a call, then walk away from the phone until you're almost out of range. That's exactly the problem I have when I'm holding the device, it doesn't matter where I am distance wise, the best audio call quality I get STARTS where most phones get when you're too far from the device. Ideas?)
After weeks (3 straight) of searching, I have to finally ask.
Does anyone else have an issue with the quality of their bluetooth connection (calls only) regardless of brand and distance from the phone?
I've purchased nearly 13 different bluetooth devices trying to fix this. Changing the distance from the actual handset (experimenting if there's a different to if the Hero is plugged in or not), the price of the bluetooth unit, what type it was (speaker phone unit only, carkit, headphones, ad2p or not, etc etc), and I still have a poor call quality call.
Reception isn't an issue, I've tried from full bars to almost no bars, and in every instance, when I disconnected the bluetooth and went back to using either speakerphone, headphones, or directly on the device, the noise went away.
You can only hear the noise when the remote party speaks, and it really sounds like the old analog bag phones in bad reception. Is there anything as far as changing settings on the bluetooth to improve the audio quality?
not really. the BT module sends information to the receiver and the receiver decodes that into audio. so you cant really set an EQ for BT with android at least so it basically depends on the receiving unit. while music is playing turn the volume down to 75% on the phone and thats the best quality you will get. im an audiophile and it works for me.
I have a Plantonics Stereo BT.
It works great on my Hero... Much better than my HTC Diamond!
Haven't had any trouble from my Jawbone 1. The sound quality isn't as good as it was on my TP, TP2 or Pre but it's ok. Haven't had any weird noises. But it does randomly disconnect from my Hero. Well the phone says it is still connected but I get no call notifications through it and when I answer, the audio is through the handset. Even right after I finish talking to someone through the BT. Gonna have to chalk it up to the Hero cause I've had no issuse with it on any other phones. Best BT ever in my opinion.
Yeah, I don't know. I have used the Jawbone II, Jawbone Prime, Moto H12, Moto H790, and Plantronics Voyager Pro all with no problems in sound quality, also audio quality is very important to me because I do have some hearing loss. My call quality with the Hero isn't quite as good as with my old Blackberry Curve, but it is still very functional as I use it at least an hour everyday. If you have gone through that many headsets it is quite possibly the device itself.
I don't know, I have 3 Hero's and I honestly don't like the quality of sound on any of them. One of them is just straight stock. I just wish I could get it with a clear quality as my old dumbphones have. I think I've been helped to discover the answer to my question, thank you all!

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.

[Q] Bluetooth car audio sounds bad

I have a car stereo that supports streaming Bluetooth audio, my MyTouch 3G Slide sounded great with Pandora (on high quality) or playing MP3's but on the MyTouch 4G there is definitely something 'wrong.'
The audio sounds slightly distorted on both Pandora and MP3s, mostly on high sounds. reducing the phone media volume does not help, it sounds like a bandwidth issue (such as an A2DP audio profile not being set to the right bandwidth or sampling rate).
Anyone else try this out yet?
EDIT: I found this could be because of the A2DP 'bitpool' setting being too low? Similar issue on the Evo.
Really, no feedback?
I have tried it but my bluetooth adapter i think is messed up I have the alpine one on my evo and my mytouch it only plays through 1 speaker

I stream daily music over bluetooth to my Madzda 2010 (built in bluetooth) and except some static crackling once in a while it sounds great. I had a N1 before and the sound is even better I think. I think there was a special issue with Pandora and other "internet radios" and the newer Android versions. I think that Google changed something to keep it compatible or so. Not an expert in that.
mine sounds as good as my vibrant did... have you tested a bluetooth headset for calling or audio to compare? maybe a hardware issue if it sounds bad there too...
I picked up a second Mytouch 4g for comparison - no change on the bluetooth audio, both have the same issue with high end audio crackling via car audio (plugging in the analog cable sounds fine on both).
Interesting side note, the LCD on Mytouch #1 had a slightly pinkish hue whereas Mytouch #2 was what I would call normal tint. The pinkish hue was particularly noticable on white fonts or backgrounds which appeared off-white, or Grays which appeared slightly pink.
So I'm keeping phone #2; the bluetooth issue is most likely software related. If that is the case, I hope it will be fixed with an eventual root mod.
I just wanted to add that the myTouch 4G I just got is working fine when using PowerAMP to my Mustang with SYNC. No crackling or other issues at any volume I could stand. I did notice that the stock music app wouldn't respond to AVRCP commands unless it was brought into focus, which was kind of lame and why I went to PowerAMP.
Cyanogenmod resolves this issue
In my particular situation, with a Nissan OEM radio supporting bluetooth streaming audio, switching to the latest Cyanogenmod Nightly build fixes my audio quality issue. No more audio that sounds bandwidth limited, something resembling a 64kbps MP3.

Bluetooth Audio Quality

I paired up my new Focus with my 2010 Acura TL yesterday. As I was driving home from work and talking, the volume from the car's speakers ranged from high to low and eventually dropped the call. I thought it could signal strength related but I had 5 bars so I tried again. This time the call didn't drop but the audio was horrible. Since yesterday I've tried to make calls in several areas of town and the call quality is just not very clear. If I talk and listen normally through the handset, the call quality is good. I have an HD2 that doesn't have this issue so I am wondering if this is Windows 7 related...
i have a bmw and have experienced similar results at times. though i think my iphone did have its own set of problems sometimes also. i have noticed the increase/decrease in volume before, though. it would be nice to know the source of the problem. likely the phone, not the OS i would think. my phone has never disconnected yet.
i don't make a lot of calls in my bmw really, but i'm getting addicted to the WP7 so i don't really feel like i will be able to trade in and go back to the iphone at this point if the problem is with the focus and not just needing a software update. though it would be nice to have an answer.
I am also disappointed in the quality of the Bluetooth connection between my Focus and my Acura TL (2009). I had the Focus with the same car, and no problems with the Bluetooth connection. With the Focus, the sound quality is terrible, and I often lose the connection between the Focus and the car. Not a dropped call, this can happen with 5 bars, its the bluetooth connection that drops.
Has anyone been able to improve their bluetooth connection?
The bluetooth in my 2008 Altima is useless with the Focus. It's all garbled up and just unusable. My original AT&T Tilt was the same way. I think it has something to do with the Bluetooth stacks used in these phones. Sadly, Nissan isn't planning on updating the firmware in their handsfree kit for my car, so I just got a good Blueant headset. Not the ideal solution, but it's better than nothing since I drive a stick!
I use mine with a clarion deck. Works and sounds flawless.
I have an aftermarket Sony deck in my car.. Bluetooth call quality is generally good but when it comes to audio streaming..it's hit or miss. I'd say 50% of the time there is always a loud 'hissing' sound in the background which makes the music sound like I was playing it off an old cassette. Other times the music is absolutely crystal clear without any hissing or background noise what so ever..as if I was playing it off a USB drive or CD. I use Slacker to stream music or songs stored on the phone through Zune.. same thing. At times I have to reestablish the Bluetooth connection several times before the hissing disappears.
I use my focus with a Sony BT Stereo and works fine. And all the in/out calls works flawless. Maybe is the BT profile (if the stereo don't have AD2P profile, the phone works in mono instead stereo).
I have the same problem with the sound volume going up and down. 2006 Range Rover. I finally gave up on using bluetooth in the car. My orevious HTC Focus and my wifes iPhone both work fine in the car
I have the Sony MW600 Stereo BT headset and a 2010 Mazda 3, both work flawlessly

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:
