Poor Bluetooth audio quality - EVO 4G Q&A, Help & Troubleshooting

Hi there I bought a Sony MEX-BT2800 radio this weekend and it has a built-in Bluetooth receiver for phone and music. My EVO pairs fine with the radio but the sound quality is really poor I have background static and a hissing noise whenever the bluetooth is being used. I thought perhaps it was the radio so I tried my phone on there floor model and I had the same noise problems. It could very well be the radio but some reviews I've read online from other buyers say there Bluetooth audio is crystal clear using there Iphones. I had my old HTC Excalibur lying around so I threw some mp3's on it and tried that phone on my radio and the static was still there but much quieter and the hissing noise was gone. So now I'm thinking it could be the phones Bluetooth radio that's causing the excessive static.
So I guess my main question is. Is there anyway to possibly adjust the bluetooth driver or audio stack to work better with my radio. I remember back in my G1 days Cyanogen would release new roms with bluetooth stack fixes.

This might be self-explanatory, but double check that the volume on your phone is all the way up when streaming. I get some hissy noise when the media volume is low, but I know that the sound quality of the bluetooth on the EVO is very good when paired with my car audio (at top volume), might be that you have a defective device.

Yeah I tried some different volume settings. Tried low med and high volumes on the phone didn't really matter what volume was on the phone. It must be the built in bluetooth module in this radio. I'm assuming your setup uses an external bluetooth module?

I have a Dual brand deck installed and I also bought a separate bluetooth adapter (with a mic and a 'call' button) that attaches to the rear of the deck via a cable, made by the same company. Maybe see if you can try connecting your EVO to a different type of audio device, if the problem persists your phone is likely at fault.

I'm having the same issues with my EVO on a different device - specifically the blackberry bluetooth media gateway. I have a little more technical details posted over here:

I've noticed a lag while using Plantronics Discovery headset. The headset was working fine previously with an HTC Fuze. So, I was under the impression that this was probably due to a faulty blue tooth stack on the device. Has anyone else had similar experience with Plantronics or other blue tooth headsets?

Jabra BT headphone
As promised;
I got the Jabra headset yesterday, and last night I was able to try it. First of all, sound quality is better than expected. Setup was somewhat confusing, since the manual is not so clear. But, I managed. Made a couple of phonecalls, all fine. Overall, nice set of headphones. Luckily, the flashing blue leds can be turned off.
Hi
I use the Anycom BSH-100. The Headset is not bad at all, with HS/HF/A2DP/ AVRRCP and a up to 200 h standby + upto 12 h music playtime.
Tech data here: http://www.anycom.com/products/bluetooth_audio_video/stereo_headset_bsh_100/?id=102&partno=CC3300
There is no buildin Microphone. A small (about 3 cm) mic is attacht to the side mini usb-jack. This mini usb-jack is also used to charge the batteries. Most of the time i forgett the mic, when charging the Headset, so i use the Headset often to listen to mp3s and recive calls without using the headset. ( a bild in Mic would be better) The headset goes to mute when a call comes in.
picture here: http://files.anycom.com/images/products/lifestyle/cc3300_lifestyle_01.jpg
+ (plus):
Handling is very easy.
Long Standby & playtime
small transport size (faltable)
- (minus):
seperate Mic
Sound Quality is OK but not as good as a normal wired-headset. (maybe normal for BT)
no option to turn of the flashing blue led
best regards Oliver
Hi, Anyone using Jabra Bt320 with the Touch? I tired to connect for stereo headset but its fails. I had the same problem with Dopod 810 but some after making some changes in the registry the problem was solved. I tired the same tweaks in Touch but it fails. Any suggestion from the forum? Thanks
I used the BT320
and the stereo was fine. I also made the adjustments to the registry and it carried on working fine.
However, I sent the unit back because I bought a Jabra 120s with it and found that, after initial pairing problems (which went away), there was an audio lag which made watching TV rubbish!
When you pair with the BT320s, you should have the option to use it as either
1. a hands-free or
2. wireless stereo.
If you don't, delete the device from your Touch then...
...plug the BT320s into it's charger, three times, for 4 seconds each time.
Now pair again and the option for wireless stereo will magically appear.
Try Motorola S9. Nice and solid. Matches Touch design too.

You get what you pay for comes to mind with BT headsets.
I have yet to come across one headset that plays great stereo sound
and gives you great call quality. However, for stereo sound the Motorola
S9 kicks arse over anything out there and the Jawbone does the voice
calls better than anyone out there. S9 is around $100US and the Jawbone
is $130US ish. Not cheap but you won't be looking to replace them because
they don't do their job. Now if you have a big melon the S9 maybe a problem.
AE!
Hi.
I got the HT820 from Mototola.
Sound is good.
Easy installation on Touch.

Looks a little bit spacy but fits good.
AND I payed 12€ for it on ebay.de.

firmware can be found here
http://rapidshare.com/files/51865424/JabraBT320swebupdate_1077.zip
Please read the instruction to update the firmware
Well i got the Motorola BT820 last week, very satisfied
great sound nice volume, little weakness but accepteble by my standard
when theres a lot of static noise the build in mic does piick up on that a bit.
i use it for mp3 mostly, and o yeah its comfortoble too
price is nice if i compare to other headsets,
still thinking about trying the new logitech headset
is there anybody who has experienced it
I have posted a question regarding a small problem with the Bb20s right here:
http://forum.xda-developers.com/showthread.php?t=326489
This is a description of my problem, as posted. Does anyone have an idea?
---
Received my Jabra 620s yesterday. First impressions: it is quite big and heavy, but it is better than earplugs ;-) Sounds quality is quite good.
Here is my problem: After pairing the headset with my device, everything behaves as expected until some event (this happend on multiple occasions, different trigger but the same result): the headset controls still function (i.e. I can skip songs etc), but the HTCs audio is routed to the HTC speaker instead of the headset. I cannot fix this, the only way is to remove the bluetooth connection, repair and I am good to go again.
I'd second the comment on the Motorola S9. I got the S9 to go with my old magician, but now that I've upgraded to the Touch, things are even better.
The S9 workd flawlessly for stereo music and also as a regular hands free headset. I can't tell you how many times I've been out jogging, litening to music and I get a cal from people. They say the call sound quality is good, but always wonder why I'm breaking fast.
I hve changed to HTC BH S100 (in-ear is better for jogging)
sound quality is good, no problems...yeah should be no problems when using HTC stuff only ;-)
i found the Motorola S9s to be outstanding. I have never been so happy with a BT headet.

bluetooth car receivers

hey guys,
anyone have any experience using bluetooth to stream audio(music) to a car receiver? how is the qualitly?
i'm in the market for a new head unit and i would like go wireless. i had been using the headphone jack to the aux port but i got rid of that car. i can't post links yet but i was looking at this model from crutchfield: Pioneer DEH-P6200BT
I got one for my truck, I THINK it's model: Dual XHD7714.
I've owned mine over 6 months now, run it hard, have had everything connected to it and it works well.
After I got my Evo, I started exclusively using the Bluetooth connectivity for Pandora and local media I had copied to the SD card. Never had any issues. Phone calls come through clear as well. You can even control the basic play functions from the head unit as well (to your phone).... such as skip songs in Pandora, pausing, etc.
I have it hooked up to multiple amps (full speakers, subs, etc)
No issues at all.
My Evo and the radio connect very quickly every time I get in the truck.
Not bad for $100.
I have had three of the Sony Xpload series recievers, and all of them have worked flawlessly using Bluetooth on my Evo. The only issue I have seen is that with the windows down or a loud interior the call clarity is poor, but no worse than using the phones speakerphone.
I use BT exclusively...no more cd's, no more radio, etc. Just make sure your head unit can stream...a lot of them advertise BT, but most will only do BT calling.
Agreed. I just put in a Kenwood DNX6160 with integrated BT. It's an awesome radio. The lower models require a separate BT module... How silly is that... Except that the lower models + the BT modules enable the A2DP, while my higher model with integrated BT can only do phone.

I have a JVC KW-AVX740 with built-in BT (audio & phone use). The audio is decent to good but the phone use is terrible. I have a Plantronics Voyager Pro for my calls (overall, a great bt device).
At this point, I don't use my phone much to listen to music. It is convenient not to carry another device...but I've been carrying 2 devices for so long, it's habit. Plus I don't want to compromise my battery life & phone usage (for music purposes)...as it is my primary communications device.

[Q] A2DP quality.. Does the BT stack just suck in general?

I see other threads, but didn't find a concrete answer. I recently got a BT deck and I currently have CM7 on my evo. When I stream over a2dp there is a "tin" noise on the high notes no matter if I'm using Pandora or just playing MP3's straight from device. I see it on other threads described as "high pitched metallic noises". I can jack in by aux and play the same songs and they sound wonderful.
So really my question is think it is the ROM or just A2DP being normal?

Nevermind.. don't buy a clarion z500. I tried two different devices and same issue.
Yes, the BT stack that HTC uses does indeed suck. CM7 uses a much better stack. Though my impression is that A2DP at its best still isn't that great. I don't have a really good A2DP device anyway, so I'm not sure how close it comes to wired when it's working well, at least for my picky ears.

Suggestions for a BT enabled Car Deck

Alright, just got a new used car.
For my current phone (Captivate) and any future phones/tablets I buy (Nexus/7) I just wanted to know which decks that anyone out there has been using that works well for calls and playing music.. My BT Motorola T305 speakerphone is a bit spotty and would like to just integrate everything into the deck.
For reference, the devices will be plugged in while in the car, so power consumption is not an issue. Thanks all.

I have the alpine 136bt and it works great with my phone.
Whoops sorry I haven't responded to this. I'll definitely look into it thanks.

Jabras are usually the best for cars..try them out..
Dension Car Dock(nice design, power usb and audio line or FM) or bluetooth kit for stock radio.
I have only used Kenwood and Alpine decks.
The Kenwood has better noise cancelling external mic for calls. Problem with Kenwoods was the bluetooth features weren't the same across decks, as price went up you got more bluetooth profiles(say like A2DP). i.e low end deck has bluetooth for calls only, higher end had you could call and stream music with car stereo as output speaker without having to hook in a cable.
The Alpine was more of the same, didn't like the external mic as much. For Apple products which you don't have it had integrated Pandora to control the app from the stereo. My next purchase may revolve around how it handles the phone address book.

BT audio call quality (mic only)

Has anyone else experienced poor microphone quality over Bluetooth on their VZW HTC One?
I'm able to stream audio perfectly well, and I also hear the person on the other end, in a call with clarity. I am however receiving complaints from those who I'm calling saying that it's not as clear as when it's on speaker (yes, my windows are rolled all the way up).
I'm using the same setup which I used on my Galaxy Nexus, no hardware changes other than the One.
The BT accessory I'm using is the Kinivo BTC450 Bluetooth Hands-Free Car Kit - supports aptX
Any help for troubleshooting/workarounds/known issues (consensus)/solutions would be very helpful.
With gratitude,
-MM (anyone know how to change my XDA username?)
I don't have that accessory but both my vehicles have the bluetooth in the navigation screen thingy and I haven't gotten any complaint. Although I haven't specifically asked if I sound weird or anything.
Sent from my HTC One.
My call quality has degraded ever since the small update Verizon pushed out earlier this week. I am having the exact same issue.
I have numerous BT headsets and all my friends say sound on their end is horrible, like the mic is way over sensitive (too loud) and becomes distorted/garbled. I am pulling out my hair. Drive a truck, must use headset.
