Stereo Headsets with full AVRCP Support on Prophet

Having spend several hours searching for information on the extent to which various stereo headsets are fully supporting A2DP and AVRCP on the Prophet with the A2DP hack, and not really getting a clear overview, I thought it might be useful if a thread was started to list the headsets in common use with an indication of their capabiliteis. Hope people will contribute in providing a useful resource:
So here goes: I have a Globalsat BTH-820:
What's Working:
Note: Only tested with Media Player 10 (results may it seem differ with for example Pocket Music/Pocket Player)
-Once paired, connects with a 4 second press of the On-Off button.
-Next and Previous track buttons work.
-Volume Up and Down work (amplification is by the unit, not the PPC)
-With the Voice Command hack via BT, MS voice Command can be heard through the headset and replied to via the built-in mic
What's Not Working:
-Play/Pause. Audio can be paused and stopped remotely (the latter with the on-off/call answer button) but cannot be resumed without using the PPC.
-Voice Command initiation: Has to be initiated via a button on the pocket pc
Other Observations:
-Sound quality is pretty good so long as the pocket pc's volume is set at max and the BTH-820 volume control is used with restraint. Background noise becomes apparent when the BTH-820's volume is cranked up too far.
-No pauses, skips or breakup of signal if within range of the PPC. Signal strength is pretty good too (though I think primarily because the Prophet's bluetooth signal is particularly strong)
-Bass is good but treble is a little thin and metallic (I think in common with all MS BT Stack A2DP implementations and down to the poor SBC compression algorithm).
Note that the BTH-820 works perfectly on devices with the Widcomm BT stack. On the iPaq hx4700, for example, the sound is very good indeed.
Even the h6340 (running a slower OMAP processor than the Prophet) acquits itself very well
Hope this helps.
Cheers,
Steve

Try use Pocket Music Player 4.2.6. All AVRCP function is worked. :lol:

Good to have a Thread like this by now. I want to buy the Motorola HT820 and i like to have good Bass - I friend of mine has got the Sony Walkman Mobile Phone with these awesome in-ear Headphones.
Does a BT Headset have the same/better Sound than a wired one ?
What about the Motorola ?

Battery drain?
How much more battery is drained when you listen to music with bluetooth compared to thru a normal "wire" from the phone to earplugs?
Thanks

Hi: I've not really attempted to keep track of battery drain. There's obviously the overhead of having Bluetooth on and the processing required to compress the audio for transmission. Nothing like as much as with WiFi on, though.

Steve

I have:
Sony Ericsson HBH-610
Doesn´t seem to work at all :=(
Can´t get it to make me an offer to check the box for "use as wireless headset", got the option when I rightclick the icon, although it´s greyed out.
My guess is that this headset can´t be used for this, anyone who have it working?

I have the Plantronics Pulsar 590 and they work flawlessly with PocketMusic.
The track fades makes the whole experience a lot better....
Best regards,
Rayan

Moto HT 820
AVRCP works with WMP, Pocket Player 2.72 and up with gen_wmhost.dll plug-in, PocketMusic 2.6.XXX. SOmetimes with WMP u do have to tap play|pause on the screen once to make it work from headphones.
Auto reconnects, however play|pause button also initialises connection.
Uptime: around 12.5 hrs of continious playback, whereas JAMin/display off, Bt on, GSM on, Non overclocked CPU, music from SD card/ stays for something around 7 hrs (6.5 when overclocked to 240).

Bluetake i-phono mini?
Hi,
I am looking to buy the Bluetake i-phono mini (a pain to get hold of in Australia :shock: ). Has anyone tried to pair with this set of headphones (and what was the quality like?)
Cheers,

pocket music player
stevep,
I have the same bluetooth bth-820 and have the exact same issues with windows mobile media player.
But goddamn, sas90850 is completely right. Pocket music player solved all the issues. Play/pause now works, plus it has an equalizers and aac support.
----------------------------
Update 7/26/2006:
PocketMusic was just too resource heavy for my HTC Wizard. Even though my Wizard is overclocked at 264mhz, I still would get skipping, white screens and having to constantly reboot because of application freezes. PocketMusic doesn't work reliably with the Wizard.
I did however find another, lighter and arguably better player. PocketPlayer by Conduits.
First install version Pocket Player 2.8. AVRCP will not work until you install WMP plugin adapter 1.1. Everything works and it is awesome. The program has everything you need.
------------------------------
Pocket Player version 2.8
WMP plugin adapter 1.1
HTC Wizard (Cingular 8125)
Qtek OS 2.17.7.2
Globstat BTH-820 Stereo headset

I do own a Anycom BSH-100. Always skip every 20 sec. Never got it work with nothing.
Looking to change it.
Option.
Bluetake mini with they audio gateway
BlueAnt X5 (are they the same as the sonorix???)
Globalsat BTH-820 with BTA-830
if i could find an audio gateway
Jabra 620s
Motorola HT820
Any other suggestion would be welcome.

Hi: Downloaded Pocket Player 2.8 and can confirm that it works well with the BTH-820. I can recommend this combination: no pauses or dropouts on my JAMin.
I believe that Conduits are using sbc.dll for audio compression, so some sound quality issues do still exist, These can be compensated for to some extent by using the equalizer built in to Pocket Player. In the longer term I hope MS will re-visit this code: Broadcomm's (Widcomm) A2DP implementation produces much higher quality sound...

Steve

BengalBoy has a review of them and based on it, I ordered one from ebay. It's bluetooth 2.0 with A2DP and AVRCP, so it should work with any device that supports it. It should be a week or so before I get it, but it looks like it will work fine if you have a device that supports it.

I just received mine from Expansys. I have an i-mate JAMin with i-mate's latest WWE ROM and smartmobile.se's version of the A2DP patch and I have used Windows Media Player and PocketMind's Pocket Music:
+ Sound quality is excellent!
+ Play/pause works.
+ Previous/next works as well.
- The display does not show song details.
Using the headset for phone calls works well and the display shows the caller ID. But the phone seems to be unable to use the headset for handsfree and wireless stereo at the same time as the phone doesn't want to switch back to wireless stereo once a phone call has ended. I have to go in to Bluetooth settings and mark the headset for wireless stereo again to switch back to music. I suspect this could be a problem with the "unofficial" support for A2DP on the Prophet and not the DS970.

I've succumbed and ordered a pair today.. looking forward to getting them working tomorrow/friday depending on the delivery time..
Need to get my head around the fixes for my m600 now...

I don't get it, if you want wireless headphones why buy these? You might as well just plug them in to your device.

Wireless refers to lack of wires between phone and headphones. The wires you have on the DS970 are just long enough to allow you to keep the receiver/remote in your shirt pocket, while you can keep the phone stuffed somewhere else . . . (no more embarassing questions about why those headset wires going down the front of my pants!)

One thing that kept me from buyin the headphones is exactly this: when you're wearing a shirt or coat, you can keep the DS970 in your pocket. but when you wear a t-shirt or sweater, you have nowhere to tuck them away, and they'll just be hanging on your chest, causing all sorts of complications when you bend over and all sorts of weird looks from passerbys...

Wireless Stereo problem on 8125?

Hey, humans!
After searching through the forums for a couple of days, I thought I would go ahead and post to ask if anyone has a fix for the following problem...
I recently purchased the Jabra BT 620s stereo Bluetooth headphones, tapped the A2DP cabs, and got wireless stereo working (along with all of the buttons and the mic) right away.
Unfortunately, every time I turn off the headphones and reconnect them, they connect to the phone as "Hands-Free" only. In this state, I can use the answer/call/play/pause/etc. buttons and the mic, but audio is delivered through the 8125's speakers and not the headset. To fix it, I have to open the BT settings, click on the Jabra phones, Refresh (because it still says that the set is connected as "Hands-Free" and "Wireless Stereo"), and reactivate "Wireless Stereo" every time I want to listen to music.
Is there any trick/registry tweak that could help me bypass this extra step? Oh, and does anyone know of a media player that doesn't hog my resources like WMP, uses AVRCP, and can play streams?
Thanks in advance!

In response to my own (2nd) question...I've read that TCPMP respondes to AVRCP commands.
Does anyone know how to get them to work with the Jabra BT 620s headphones?

I'm continuing to look for a solution to my problem and find an alternative to WMP10, which sucks up so much memory.
I have finally managed to get Pocket Player 2.72 (http://www.conduits.com/products/player/download.asp) working with AVRCP. Although it is supposed to work right out of the box, I tried using it and received no feedback from the Jabra BT 620s's buttons.
While looking for a WMP today plugin -- one that I had hoped would have a smaller footprint while still allowing AVRCP controls to function -- I came across a post and eventually found a .dll for Pocket Player that allows me to use my Jabra's controls to influence the player.
Unfortunately, Pocket Player is a woefully bad player (even worse than WMP10 in my opinion!) and I can't get much use out of it because it “skips” constantly and forces the screen back on (it doesn't automatically shut off again) with every command from the headphones. However, for everyone who prefers PP and can't get Bluetooth to work through it, trying downloading this rar file (http://www.modaco.com/index.php?act=Attach&type=post&id=19163), unrar'ing it, and placing the enclosed .dll in your Pocket Player directory.

I personally really like pocket player, but you need to wait for v2.73 out soon apparently. If you go to conduits forum you can see alot of info on this issue.
I find it plays beautifully thru iTech Clip R35 (I admit I have a different device ie jamin).
But to your first point, I still have that problem as well, I have to manually switch on the bluetooth stereo option, I haven't found a solution for that yet.
cheers

Hi, I just bought the BT-620s and have exactly the same problem you have mentioned, otherwise a great BT headset.
Did you ever manage to find a fix for this problem?

BT Headset works for calls but not music??

I have a 8125 with a Nokia BH-600 bt headset. It works great when talking on the phone but I really want to listen to music too...
Is it possible to play music through the Nokia BT headset?
I have Media Player, Sound Recorder, and the CORE movie player but none of them play sound through the Nokia BH-600 headset! I also have a Moto H700 if that makes a difference.
Thanks!

I am not an expert on this topic so someone can correct me if im wrong, but you cannot play music through your bluetooth headset unless the headset is A2DP compatible. You also need the A2DP hack that can be found here:
http://forum.xda-developers.com/showthread.php?t=263735&page=7
Anyway, to get an A2DP headset, look on eBay; you can normally find them for around 60-80 shipped, for a quality one. The hack is a cab file that just needs to be installed before pairing the headset.
Hope that helps.

Being dumb here... how does this hack work?

I posted the link in my above post. Basically, just download the hack, copy it over to you phone, and click on it using file explorer and it will install. I am pretty sure it just adds to registry tweaks and DLL certificates, but I am not 100% sure. All i know is that is works great! After the install and a soft reset, when you pair a A2DP headet, it will have the option for setting as wireless stereo. Take a look at the thread above for more information.

Ah, so then any audio that that gets produced on the phone gets streamed on to the BT headset?
Sounds promising. I was wondering if there was a way to get navigation commands to go through my car BT kit.

I also wanted to be able to do that, as I have a bluetooth speakerphone in my car. I do no think this is possible with just a regular bluetooth headset or speakerphone.
However, I do think if you have an A2DP headset the navigation sound will come through. I am not sure if your car kit is a speaker phone or a headset, but if you prefer a speakerphone in the car (as I do), I highly doubt it's possible, because I dont think anyway speakerphone is A2DP enabled. Nevertheless, people on this forum have done more amazing things so search around, you may find something.
And yes you are correct, after the pairing, any audio that gets produced by your phone will come via the headset (hence my thinking for navigation working with A2DP headsets)

Hmm, i have got a parrot ck3000. Not sure if it is A2DP compatible. Is this hack/cab file uninstallable? lol, im asking so many questions! I think i might just give it a try.

Heres a question (as these forums are a mess and i can never find anything), Is A2DP included in any of the latest roms? I am running the AKU2 rom that t-mobile last released, so i assume that some of the cooked roms are miles better.

your options
There are 2 ways to approach this issue:
1.) A2DP hack or updated ROM (for the best possible sound quality) needs an A2DP compatible headset/headphones or home BT transceiver.
2.) Mono BT hack for BT headset (you lose Voice Dial) has the lesser sound quality of the mono audio channel (the one you hear when on a phone call) See this tutorial for more details and options.
I highly recommend any and all BlueTooth articles by Menneisyys one of our Moderators.
See his articles on BlueTooth and more here.

Awsome! Thanks for the link to that article. I will give the BTAudioNav a try to see if this works how i want it to! Coolio! Thanks

Ah balls it. It looks like its just another constant streaming program. Shame, i would have loved to just get the commands to be said and then the radio wont be contantly cut out.

my 2cents
Just installed this .cab on my wizard (o2 xda mini s, G3 un-updated at all.)
Works a treat, I'd foolishly bought a a2dp headset without checking compatibility and now it is compatable.

Trinity A2DP problems - Temporary solution

Well, I was unsure if I should post this under one of the old posts, but I decided to start it as a new clean post...
Many are having problem with "hissing" noise, joint-stereo and low bitrate(or bitpool). For my sake, I've tried "fit4cat - Hermes Tweaker", "Sleuth255 A2DP fix" and several other methods, but without beeing able to get the soundquality I want from my headset.
Now, this is what worked for me after tweaking around with the registry a while, and endless pairing sessions
Download a registry editor(I use PHM, http://www.phm.lu/Products/PocketPC/RegEdit/ <- Download the PocketPC 2002/2003 ARM/PXA)
1: Turn off bluethooth on the Trinity
2: Unpair the Trinity with the headset(Delete the headset from the list!)
3: Change the following registry settings:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings
MaxSupportedBitPool=80
MinSupportedBitPool=40 (or more if you want)
(if these arn't there, add them!)
And DELETE:
UseJointStereo = 0/1 (depending on whatever you have put there before)
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev]
Priority256=149
(let the rest be as it is)
4: Reboot
5: Now, DO NOT use the headset for direct pairing!(since you've already added your phone to the headset, pressing a button on it will useually pair it back with the Trinity) <- This seems to be the function that triggers the sound-problem...
Instead, set the headset in visible mode, and use the trinity to pair(search for new devices), when you find the headset and pair it, you will hear the pairing-sound from the trinity-speaker, and NOT the headset.
Now you can enjoy high quality stereo sound without any disturbance
But, the problem comes when you turn off your Trinity, or the headset. If you try to connect the headset and the phone by using the connectbutton/playbutton on the headset, it will pair, but this time you will hear the pairing sound in the headset, and then you have all your problems back... So then you have to turn of bluethooth, delete the headset from the trinity, and add it back once again by turing the headset in visible mode again.
So the solution to this, is to go to the device list on the trinity after you have lost connection with the headset(this is if you have turned of the trinity or the headset), and hold the stylus on it and choose "Use as wirelss stereo" and "use as handsfree"...
Thanks to all of you guys here who have posted solutions to the A2DP problems And if anyone have suggestions to other values that are better fit then the onces I've supplied, share them with us
And if all of this have been posted in another thread that I've missed out, the moderators are free to delete this one

Good grief, I can only imagine how many times you had to pair the headset before you noticed what was going on LOL, hope you didn't turn blue in the face
I imagine a ROM update could fix this problem.

Hehe! The thing that made me going was that I was able to get perfect sound once or twice, and since I made it work those few times I just had to find out what I actually did that made this work (And paying 175$ for the headset also keept me fueled for a while ) hehe!
I think I've used about 5-6 hours total these two days sitting pairing, adjusting settings, rebooting(ARGH!), untill I found out that the problem actually occurs when you use the headset to pair instead of the trinity

I don't understand what is it with bluetooth stereo:
quality is not good enough to listen to music 64 kbps... no bass, no medium, nothing just a hiss.
and plus you get 80% cpu (with a 400Mhz...), just to encode this crappy 64 kbps.
Yes exactly for all people having so many skipping problems check your cpu with taskmgr.
So you cannot play video with A2DP unless you have 1Ghz!!! good for battery life.
If you like music you want good earbuds. There's none with A2DP.
So what's the point again apart from having to charge one more device?

1: Well, I'm not sure on the bluetooth 2.0 specs, so If there is a spec limit on 64kbps, then this is new to me.
2: And the skippingproblem is not just connected to the CPU-usage.. But if you have some info on this issue, then please; do share it with us.
3: A2DP headset with minijack is available many places, even HTC has one. And if you take a look at DS970, you will see that it's the same as Sony MDR-series.
4: And well, the CPU usage is a issue, but that is the only part that I agree with you on..(but let us be frank, I've bought a pair of A2DP headset, so I do smell a bit "conflict of interests" here...)
And to the bottom line, I've bought the Trinity because it's one hell of a gadget, and so is bluetooth stereo So if anyone want to shoot me for that, well hell yeah, go ahead
Edit: And FYI meroupow: I do feel you are a bit rude in the way you wrote that response, or at least a bit arrogant when you post a comment like that. Trying to mock people who have bought A2DP headsets and are tweaking and fixing issues to make them work correct(this also goes for GPS on the phone, black coating comming off, improving camera quality, getting the ATI ImageOn to work correctly... etc) . And I must honestly say that yes, you do have some points there, but you should be able to present your views in a much more polite way...

Sound better but discontinuou. Impossible ear music. The sound goes on and off continuously. Why?. How can I do?

I am sorry if you felt I was being rude.
That was not my point and It was probably the wrong place to say what I said.
It is just that just like you I bought this A2DP stuff with my Wizard.
Just like you I tweaked it as much as I could and managed to get it work.
The problem is when it comes to sound quality is important and just working is not enough.
When you show your happiness because it's finally working, people think you are happy because it's good and they are buying it. And get disappointed too.
I just wanted to warn people on the fact that it's not working to watch movies because of cpu and that a 5$ earbud will have far superior sound quality.
It's just a toy and by no way a mature technology.

I've got a CB2530, hard to pair and I still don't know what do I do for the pairing to be successful, but I do manage to pair it after a few attempts, on the registry I just disable jointstereo, set the MaxSupportedBitPool to 320 and the quality is quite nice and with minimal skipping. High cpu usage of course, but if I set the MaxSupportedBitPool to 80 the quality is quite crappy and the device gets equally sluggish(gets worse when you touch on the screen, as K-Rally does even with the new ROM).
As for the pairing, I still haven't confirmed, but I think the registry setting that enables the bluesnarf option on BTCrawler has something to do with it(the bluetooth ISC mode thing), because right after setting it I managed to pair the headset right away, the thing is, I was also successful in other occasions when I hadn't set that reg. option.
Hearing the pairing sound from the trinity or headset doesn't indicate anything on my case, and I think I've already tried these reg settings you mention, but I'll try them again as soon as I get home to see if there's any difference and post the results.

Install the Widcomm BT stack. With that, you won't have complaints - neither have I.

Does anyone know what is changed when you DO pair with the button on the headphones? With some models, you MUST do it because, otherwise, the music will be muted after about a second (see http://forum.xda-developers.com/showthread.php?t=282008 for more info).
I've searched around in the Registry for changes, without any success. It's possible we could directly edit the headphone connection-dependent parameters set AFTER the headphone's initiating the connection to avoid sound problems. If we knew where they're stored, that is.

I am sorry if you felt I was being rude.
That was not my point and It was probably the wrong place to say what I said.
It is just that just like you I bought this A2DP stuff with my Wizard.
Just like you I tweaked it as much as I could and managed to get it work.
The problem is when it comes to sound quality is important and just working is not enough.
When you show your happiness because it's finally working, people think you are happy because it's good and they are buying it. And get disappointed too.
I just wanted to warn people on the fact that it's not working to watch movies because of cpu and that a 5$ earbud will have far superior sound quality.
It's just a toy and by no way a mature technology.

BTW: is it the profile and software on the phones/PDAs that arn't handling it, or is it the standard itself that sucks? (or in other words, should I keep my headset for later usage or return it to the store)

I use Plantronics 590a and the skipping problem appears very rarely, mainly when I use volume/track buttons on headset. However, yesterday I also connected the headset to a normal stereo (via the 3.5mm adapter) and noticed the same occasional skipping. So in my opinion the skipping issue problem might be from headset, not Trinity.
I also tried a Nokia stereo bluetooth headset and noticed serious skipping problems - unusable.
PS: there is indeed a skipping problem if I open/close other applications while listening to music. It looks like the processor is very busy - system very slow etc.
PPS: any suggestions for a player that has equalizer? WMP doesn't and the sound is not that great (especially when compared to my old SE P900 which had an excellent player - best I've heard so far... )

If you tell me how I'll be glad to try...
I've never managed to do it sucessfully with my Prophet (witch had the same A2DP sound quality problem as it come with taht Fu***g, crappy, buggy, foot-coded MS BT stack)

Stereo BT experience is very positive
Hi all,
As always, someone has to have a different view of the issue. I got my trinity a couple of weeks ago and went and bought a Plantronics Pulsar 280 stereo headset. Mostly because of the stereo jack. I have not updated trinity nor have I applied any fixes, just paired right out of the box, as always from trinity BT manager. It really sounds great, particularlly the base is fantastic because of the earbud design. Even you may choose the actual headset of your dreams by using the standard 2.5mm jack. I have owned a "no brand" headset (still do) but it is not BT 2.0 and I think it makes a difference. The plantronics does not skip and it sounds great. Most of my MP3 is 128k and above so no limits with that. I have not checked my registry settings as they are default rom image set. I am using ROM 1.15.412.2 and Radio 1.20.00.11 (my trinity only speaks spanish for now, hope to change that soon).
Point being that the software and quality of the headphones makes all the difference, don't be so quick to blame trinity, just a piece of my mind. Keep it up guys!!!

Yes, how do you change the BT stack on the Trinity?
Thanks.

If you haven't changed anything it might sound great but it definitely sounds MONO!

Up to now, I haven't managed to do it; see http://forum.xda-developers.com/showthread.php?t=291605 and http://forum.xda-developers.com/showthread.php?t=286094 . Sorry for telling you it might be possible - I assumed it would, as it is on most other HTC models.

theese registry keys can be the sotution!!
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"LaunchAPEnable"=dword:00000000
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"VoiceCmdDuration"=dword:99999
or use this cab, its the same!!

rom is the latest official wm6. how i check radio? oh cool, i'll try out that cab dude, and post here the results

not working bro. shudnt my pda restart after installing that cab? i installed in main memory, and i'm now using my headphones. still got the problem. your registry tweaked the voice commander, my problem is with the bluetooth. 0_o
as in, i listen to music using my bluetooth headset, i hear
EXAMPLE: BONJOVI'S ITS MY LIFE
Its my ..(no sound suddenly).........Now and never, i aint gonna live forever!
the sound is lost but the music is still playing

Getting the same problem with iTech R35 bluetooth stereo headphones and offical Dopod WM6 upgrade (ROM 3.00.707.17 / Radio 1.46.00.11).
The headphones were working fine for the last 6 months with decent sound quality after pairing. Ever since I upgraded to WM6, either the headphones or the phone are dropping the BT connection after random intervals of between 5 minutes - 30 minutes. i.e. the sound suddenly cuts off even though the PDA is still playing music and everything seems to still be connected ( the BT icon is still displayed in the taskbar). If I re-pair again, it comes back for a short while, but then always cuts off again

This is the exact same problem I have with my R35 and WM6. I have figured out a way to make it cut out on a song (a different format wma). if i just play mp3s it will start to skip and then cut out completely after a random time. So I think its WMP I tried different radios and it still doesn't work....
help us anyone!

I posted a thread but no one was able to help...
http://forum.xda-developers.com/showthread.php?t=320809

I don't think it's a WMP problem,since I generally don't use that app. It's dropping for me with Resco Pocket Radio and CorePlayer.
Getting fed up with Dopod firmware. First, it was the 'no-bass' problem with the previous ROM. Now, it's this problem...! Can't they just release firmware without MAJOR bugs in it?!

I don't want to suggest this but do you think it has something to do with the itech clips?

when i use my BT stereo headset (plantronics pulsar 260) the music stopped sometimes, like described above.
when i disconnect my headset, the music plays normally over the phone speaker. no problem at all.
i guess its just another bluetooth problem.
when my phone is in my right pocket, and the receiver of my BT-set is in my left pocket, my body is between them, it gives the same problem( i am on my ATB at the time, moving)
very strange.....and no, i dont have any metal in my body. ;-)

Hi,
I'm using Touch 1.2 U-Clip and I have the exact same problem. So it's not just with i-Tech. I hope someone will find a solution for this problem.

Think its the Bluetooth stack
I am having the exact same frustrating problem - after checking to see if it was a Dopod error (tried closing down everything else on the PPC, tried other wired headsets), I have come to the conclusion it is something in WM6 Bluetooth, as I did not have this problem in the previous WM5 on the same machine with the smae Blueant Stereo headphones - mind you with WM6, I have full function with the Media Player, that is I can pause, next track, etc, whereas I couldnt do this with the WM5 version. WM5 had a really annoying high pitched whine, otherwise worked a treat.
So, in short WM6 has fixed the whine, has brought full features to the headset, but skips (blanks) the songs. Just before each "blank" I have noticed that it sounds like the song slows up - much like an old tape player running our of battery.
Now, I have no idea how/where/who to fix this, so anybody with even half a clue, please let all of us know, this is getting quite maddening!

bump for the thread. and yea man, i have the same prob. its like a battery dead sound, as the song goes out of tune etc

a slightly different problem
i use the INDIGO LITE rom, and i use OMIZ 5110 stereo headset, and i dont have the skiping problems described here, however since upgrading to WM6 the sound quality is terrible, i feel like tori amos is singing in my bathroom (which if was true could be really great) but alas, its just crappy sound quality... i tried changing the registry BITPOOL to 58 and played with all the values there known to man (at least to THIS man) but nothing helps...

Going by the devices that have this 'dropping sound' problem, it seems to only be affecting A2DP stereo bluetooth headsets paired with WM6 Trinity devices. Or are regular bluetooth mono headsets affected as well?

Personally havent paired a mono headset, but the problem I am having is definitely a stereo one! Any solution as opposed to taking to the machine with an axe?

Anyone found a solution yet?????? Please!!!!

I am also having the same sound dropping problems.

I have the same problem as well. I have just upgraded my rom to official WM6 rom. I'm using iTech Clip Radio.
