Anyone else the same experience? Contrary to almost every other WM device I have used in the past, the voice sound quality both on BT headsets and on parrot carkits is way below par. It sounds thin and metallic.
When using the speaker on the device itself (held up to your ear) the quality is excellent, so to me there is a major flaw in the the BT implementation on the Kaiser. The x7500 sounds way better, so it's not the OS itself.
Finally, someone else with good hearing
I have exactly the same issue. Even it's tolerable but is some situations it's very hard to hear the other party. Doesn't matter what headset I am using - Nokia BH 900, Jabra JX10 2 or Jawbone - they all sound thin. I really hope that there is something in registry that can be changed to resolve this. Or maybe a different DLL. In fact, this is the only complain that I have about Kaiser. I've tried this suggestions but none of them worked unfortunately.
Increase Audiogateway capability:
HKLM/SOFTWARE/Microsoft/Bluetooth/AudioGateway/Capability
(Dword:69)(Default is 37)
[I'm assuming this is a bitrate setting, but not sure how this differs from those above]
4-Change the Bluetooth channel from the default:
HKLM\Softare\Microsoft\Bluetooth\Device
From there open the subfolders and find those labeled channel. The DWORD key value is the channel number. Change the number to something other than the default.
[i've only tested up to channel 7 because I'm not sure how many channels there are. This seems to have improved issues with interference and intermittent drops, but these issues seem to have more to do with where the device is in relation to the headphones than anything else. You'll have to experiment to see what works best with your gear and environment.]
5-Increase the Bluetooth microphone sensitivity:
HKLM\Software\Microsoft\Bluetooth\AudioGateway\Mic Volume
(DWORD:10)(Default:5)
6-Increase Bluetooth earpiece volume:
HKLM\Software\Microsoft\Bluetooth\AudioGateway\Spk Volume
(DWORD:10)(Default:5)
[again experiment to see what works best with your headset and environment]

Ouch. Just came out of an escalation meeting for which I was forced to use the TyTN II for almost an hour over my Sony Ericsson HBH pv705 headset, and I have to rephrase my first post.
The audio quality is leaves not just a bit to be desired, it is just blatantly bad!
That, I feel, is the only *real* letdown of the TyTN II
Have exactly the same issue here. Was using it today in the car using the Mercedes bluetooth kit, and the sound was very thin and tinny. On my Hermes the sound was full and fine.
It's like listening to one of those shortwave type radios
OK. Now we have to determine is that :
Hardware issue
or
Software issue.
I've briefly used one of the preproduction units back in June and as far as I remember BT was OK. But I can't be sure 100%.
Anyone still using pre-pro units? Please, check how BT headset sounds like.
I really, really hope that this is software issue. Otherwise I am afraid that I am not going be able to keep the unit .
Sorry to put this into the mix but I have actually superior sound quality using a Parrott Car Kit and a Motorola Stereo Headset as compared to previously using these devices with my Hermes device with the newer WM6 ROM's.
I have made no changes but just wanted to share my experience.

It's probably due the fact that car kit has already plenty of bass and stereo headset is using a2dp. My stereo BT headset sounds good as well.
Handset itself sounds good, wired handset sounds good. Again, I really hope that there is a way to change something in software that will fix this problem. i guess, we have to wait until device is in more hands and some hackers will find the way
In that case, my second addition to the mix to counter yours. Aside from my SE PV705 I also have a Parrot carkit (3200 LS-Color) and I have the same poor audio quality over bluetooth ...

same here ,i paired it with my car and it's worthless..i can hear the person but they can't hear me.this the worst bluetooth phone ever.

Using Sony BT Stereo headset - quality pretty good - better than TyTN.

We are not talking about stereo A2DP quality. Again, stereo BT sounds very good to me as well.
nono - this is simlpy the voice call quality through these headphones - not using the A2DPprotocol - just headset protocol.

I use the Sony MEX-5000BT headunit in my car in handsfree mode. I've used it with both the Kaiser & Wizard, and I can't tell any difference in sound quality between the two phones in handsfree mode.
A2DP is a different story -- the Kaiser is much better.
I'm having the same BT issues with my phone. Voice quality on my original TyTN was great through BT. But with the TyTN II, it is sub par.
OK, this is rally confusing. As far as i know all units have the same ROM/Radio builds. Or are they?
Let's start to put numbers:
Mine
ROM 1.56.405.5
Radio 1.27.12.11
protocol 22.45.88.07H
BT is too quiet and tin.

What type of device you have been using previously?
When you switch from handset to BT headset on the fly do you hear difference in voice quality? Doesn't seems like BT headset doesn't have the same frequency range as a handset?
I always had my HTC Tilt 2 playing music in my car through bluetooth. Now with my new HD7 I noticed the sound quality is very bad. It sounds like its streams at a low bit rate so all the high frequencies create crackling distorted. Overall sound doesn't have any richness to it. I use the BlackBerry Remote Stereo Bluetooth Gateway: http://www.amazon.com/BlackBerry-Re...M0/ref=sr_1_11?ie=UTF8&qid=1289972227&sr=8-11. The quality of the Tilt 2 paired up with it was really good. I think they need to fix this pronto.
Yeh I have the same problem too, its exactly the same if I use 3.5mm jack aux too, just far too quiet, causes so much distortion, neither bluetooth or 3.5mm sound any better. If you put headphones in you can tell there isnt enough volume at all.
Really needs fixing, seems more of a software issues as I've seen people with various WP7 models complaining about low volume.
Right now I'm having to use my old Touch Pro for audio streaming in the car.
Mine sounds great through headphones and car stereo (BT).
In the car I prefer the sound to my iPhone 3GS through BT and line out.
And the volume is loud enough using Ultimate Ears 5vi IEMs with plenty if bass
Enable the SRS Surround
Sound quality is always in the ear of the beholder, so difficult to fully compare what people consider good or bad.
I find the internal speaker, headphones and line-out (via 3.5mm) too quiet. Quality seems ok from the 3.5mm jack though.
But I tested the BT recently and at high volume it didn't sound very good on a beefy car stereo (with sub). I was disappointed, but had no basis for comparison at the time.
I have this issue too. I'm using the Sony DRBT140Q. The audio sounds perfect when connected to my G1 and Sennheiser BTD-300. But when connected to the HD7 the sound turns kind of...fuzzy on the mids. Gonna go try out other HD7s at the T-mobile store and see if it's a problem with my handset.
I also have this issue. With wired headphones the sound is OK, but with bluetooth audio the sound is bad. I tested it with a jabra BT3030 and with a SonyEricsson MW600. The sound is good with both Headsets when they are connected to my notebook.
HTC are not known for good blutooth support, I was hoping they would get their act together with this phone.
3.5 jack is fine, but bluetooth quality is aweful! was fine on the HD2.
On BT, the bass and mids are ok, but the highs are terrible, they are really crackly/distorted. You can get away with it on dance, because its not too noticable, but in Rock music, it just sounds ****e.

If you have the phoned paired via Bluetooth Sound Enhancer makes no difference to the sound whatsoever. Even if connecting to 3.5mm and using sound enhancer it sounds terrible in my car.
Think I'm just gonna have to carry on using my Touch Pro 2 until something is changed with the volume. I just think there isnt enough, you have it too loud its distorted so you turn it down and then turn the radio up but its no better because you get a lot of hiss etc.
If your listening though AUX make sure all the sound enhancements are off, they make it sound terrible. They only make an improvement through the phone speaker.
They dont affect bluetooth at all though.
So is anyone going to fix this?
I have Mozart 7 and fits the same description as previously said :
Bad audio quality when connected with Bluetooth headset (Sony Ericsson MW600)
(crackled/distorted, a low pitch noise at the background, sounds like interference from other things) - ive tried it on everywhere its the same
sounds perfect when its wire connected
This is making me really angry since i got this Bluetooth together with my mozart 7!!!
Can we notify anyone about this in particular??
I have the same problem. Bad quality when streaming via bluetooth to my car radio. With my HD2 and Windows Mobile 6.5 I had exactly the same problem for which there were registry hacks to improve this. Do you think the same registry entries still exist on Windows Phone 7?
Bluetooth audio quality FIXED!!
Ok guys here it is. I figured out how to improve the Bluetooth music streaming quality.
1. Your device must be unlock to do this. Even if your device relocks it doesn’t matter.
2. After unlocking device download and install the XAP file RegistryEditor 1.1.0.0. This is a registry Editor for WP7.
3. Once you have the RegistryEditor 1.1.0.0. on your phone do the following registry hack:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings]
"Bit Pool"= change Value data to 51.
As I suspected the problem was in the sample rate settings. After I did the hack it sounded beautiful and at full sample rate. Some people don’t have the ear to catch the difference. I like to think I have a very good ear for this sort of thing. Being a musician and aspiring sound designer. I listen to all my music in the car through Bluetooth stereo gateway so I rely on this Bluetooth functionality 100%. Here is an example of the “Value data” number translated to sample rate.
Medium Quality
Bit Pool=35, Sample Rate=44.1 kHz = 229 kb/s
Bit Pool=33, Sample Rate=48 kHz = 237 kb/s
High Quality
Bit Pool=53, Sample Rate=44.1 kHz = 328 kb/s
Bit Pool=51, Sample Rate=48 kHz = 345 kb/s
Last Note: Even if you cannot unlock your phone anymore it won’t matter. As long as you gain access to that registry and change it. Unless you do a hard reset or Windows update you will need to repeat the process or unless Microsoft slaps their head about this issue before they release that update.
Wow that sounds like a plausible solution!!
Has anyone else tried it yet? Im still considering whether to hack my phone or not.
Try it. You wont regret it.
It works! did it last night and music was perfect in the car this morning! so happy now!
Just need a reg hack that allows me to download big files from the marketplace through my own 3G signal and not wifi now and ill be very very happy!
Also set "UseJointStereo" to 0 since one of the common joint stereo algorithm uses a lossy audio compression. BT Music sounds great with these changes!
What a difference
Thnx, sounds awesome.

Verizon Trophy Fixed
Thanks for this fix! I finally got my Verizon Trophy fixed after
1. Trying to deploy RegistryEditor 1.1.0.0 only to get a deployment error
2. Trying to deploy RegistryEditor 1.2.0.0 only to get a deployment error
3. Editing the XML file in RegistryEditor 1.2.0.0, which successfully deployed the .xap but wouldn't actually let me edit the necessary values BitPool and UseJointStereo. I could change them in the editor, but as soon as I navigated away from the editor they would return to their defaults.
4. Attempted this http://forum.xda-developers.com/showthread.php?t=1271963 only to be unable to run Connection Setup app
5. Completed this http://forum.xda-developers.com/showthread.php?t=1271963&page=64 after about 10 iterations of trying to open the Connection Setup app at the exact moment described. I didn't think it would work, but it did.
So, in summary, in order to install a registry editor (1.2.0.0) AND have it edit the BitPool and UseJointStereo values on my student developer unlocked Verizon Trophy running official mango update, I had to do an interop unlock.
Took me a few days to sort through, but I'm so unbelievably happy with the result!
I have a Bluetooth headset Plantronics Discovery 975.
It supports simultaneous connectin with two phones.
In my case it is HD2 and Nokia E51.
When the headset is connected just to one of them the sound quality is very good.
When it is connected to both HD2 (Android JDMS 1.6.2 Ultimate) and Nokia, then the sound quality is very good.
When it is connected to both HD2 (WinMo Energy Touch of Glass) and Nokia, the sound quality of HD2 is very bad.
My question is:
Can I read the settings in Android, so that I can figure out what is different ( for example BitPool). I'm very nooby in Android, so I was not able to figure these settings out.
Some other tipps how to improve sound quality in WinMo?
No one has an idea??
Hi Folks!
Recently got a bluetooth FM transmitter so i can go hands free in the car and use phones music player too
However the audio is very heavily compressed when using A2DP - no bass and the top end frequencies turn to mush - ie not good enough to use
Checked all eq settings and different FM frequencies, no difference
plugged the analogue audio cable direct from the phone to the bluetooth FM transmitter and immediately got perfect sound again
I dont see many poeple talking about this on this forum or many answers but the closest seems to be windows phones can access and modify registry settings to check and increase the bitrate
My current thinking is the bitrate (or bitpool) over bluetooth A2DP is set too low, or when the phone and FM transmitter pair the phone selects a bitrate that's too low for quality audio (but ok for calls)
My question is does anyone know how modify the bitpool settings on the Galaxy S please?
I am going to get a custom ROM and will very happy when the phone is really mine so if that's what it takes I'm up for it
Many many thanks!

Samsung Galaxy S
2.1.1 Eclair on 3 mobile network in the UK
Nexus Drive Transmit Pro (Bluetooth FM transmitter music and hands free car kit)
I have the Galaxy S on 3 UK since August. I use the bluetooth to transmit sound to my Samsung surround sound system (as I don't own a stereo). I don't notice significant quality issues doing this. Are you sure both your devices are supporting A2DP. Not all A2DP devices talking nicely with each other, so you may be failing back to the normal Bluetooth frequencies which are more focus of the vocal range. I'm looking a car stereo's right now that support A2DP so I can stream my audio from my phone straight to my stereo, my phone is becoming the centre of my entertainment!!
I'm running Doc's ROM on my phone, can't recommend moving to his Froyo ROM's and an enhanced kernel enough, my phone is working so much better with his ROM, but there are lots out there to choose from.
I am using A2DP in my car too and I find the sound quality being very good.
The thing is, the default Android audio player (Music Player) is pretty poor and often it lags for me.
Since I moved to MiuiMusic (Search here) all those lags are gone and it works perfectly and smoothly in my car.
Now, as pointed already to you, all BT devices do not communicate flawlessly between each other sometimes...
works great for me, streaming from the SGS to the car CZ 509 deck
i don't even carry CDs in my car anymore
even the lovely sub base sound comes through clearly.
nothing better like a Sonic Massage meanwhile you are driving
I wanted to create a new thread on this, but then I've seen this one. Is there no one with a solution except flashing cyanogen?
It could be a setting on your bluetooth receiver.
For example, I've got a pair of Sony DR-BT21G bt stereo headphones. When you hold a special button combination, it switches it from "high quality" to "any quality", and will just select whatever bitrate it thinks is best, usually, something that sounds about half as good.
Try looking in your manual for troubleshooting and see if there are any settings that you can change on the receiver itself?

Hmm, i using Sony MW600 BT headphones. I've checked the manual, but there's nothing about quality :/
But i dont think that's the problem anyway, as i tried Cyanogenmod and it got perfect quality then. But otherwise cyanogen is quite useless for me on my Galaxy S, its just too buggy. There must be someone who can change the bitpool quality on the stock gingerbread to the highest possible...
Exact same issue for me (as described by DJ LIBRE), I have a Belkin Wireless Bluetooth Music Receiver and the sound quality is horid... it's got nothing on AirPlay which I think is still kind of average quality!
I also wonder if there is a highbitrate setting that can be adjusted?
Running CyanogenMod Nightly #130 on SGS.
After getting used to listening to 24/96 FLAC's with the Voodoo Sound mod enabled with a custom built headphone amp and semi decent can's all I can say is BT Audio is a waste of time!
Has anyone noticed whether the music player was set to 5.1 surround mode? Had a similar issue where turning off the 5.1 fixed the sound streaming...
Hello all.
I'm having problems with Bluetooth on my One. The device that I'm trying to use with it is called a Siemens MiniTek. (It's actually a hearing-aid accessory. You clip to the front of your shirt - it looks a bit like an MP3 player - and it plus my hearing aids together then function like a Bluetooth headset. So, when making a call, the sound is sent wirelessly to the hearing aids, and the device itself has a microphone on it.)
Making a call with it works okay; but if I try to use it to get audio out of my One in other conditions (playing a game, say, or watching downloaded video) then the video and audio are always badly out of synch - the sound lags at least one second behind the picture.
I'm using the stock HTC ROM, the latest one available in the UK (2.24.401.8).
Anyone have any thoughts as to why this might be happening and what I can do about it?
Mby there is too much data to deliver via bluetooth (high quality audi/video sound) and the hearing aid device is not meant to recive such a load.
When calling to some1, the sound quality is only like 24kbps or something.
Just a thought

That might result in there either being no sound at all or in the sound quality being very poor, but I don't see that it would result in reasonable-quality sound running 1 second behind the picture...?
The device itself is designed to handle fairly high quality sound: as well as receiving Bluetooth signals it can take analogue audio input via a 2.5mm stereo jack socket, and it also has a separate "base station" transmitter which you can plug into (say) the headphone socket of your TV: the transmitter then sends a signal wirelessly to the MiniTek (using a proprietary version of Bluetooth) and the MiniTek relays it to the hearing aids. Using either the direct-line input or the wireless transmitter works quite nicely, and there's no perceptible lag problem there.
I should have said, I've been onto Siemens tech support about it, and they're adamant that it shouldn't be doing this, and they don't know why it is. So I'm looking for a problem at the phone end.

i've experienced the same issues on various BT-Receivers and Smartphones. Seems to be a general issue. So far, this 1 second lag was present on all combinations of:
Phones: Samsung Galaxy S2 / iPhone 4 / HTC One
Receivers: Creative D100 / Creative D200 / Belkin BT Adapter
As i found out so far, this problem occours when the receiver can't handle the apt-x codec and audio has to be resampled to the older SBC codec. Found one thread kinda dealing with this topic, but haven't tried it out for myself at the moment. I'll do some testing later when i'm at home.
