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....

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?)

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...

Wifi+A2DP standard MS stack NO GO!

Using my bluetooth a2dp headphones with wifi streaming music[internet radio] is just impossible. The stream plays for the first 5 secs and then stops. Is there anyone who has got internet radio via wifi working with an a2dp headset please let me know.
Thanks

Hi
does it do the same when your not using the headset or is it doing then same when your using the normal internal speakers ?
Regards

I have never had any success with WiFi and a2dp on any pda I've ever owned.
I've used:
TCPMP
Mortplayer (GSPlayer)
Coreplayer
Resco Pocket Radio
and a few more
on:
iPAQ 1940 (Sandisk WiFi and also Socket WiFi SD cards)
iPAQ 2790
and HTC 8525 (TyTN)
It skips and drops and is just plain unusable. Works fine on any wired speakers/headset.
I suspect that there are two causes:
1) the WiFi and the Bluetooth share RF frequencies and are know not to play well together (its getting better, but its not perfect)
2) There isnt enough CPU and/or memory speed to do WiFi, MP3/AAC/etc. and Bluetooth all at once.
Non-a2dp bluetooth headset and WiFi skype also seems to have some issues on the iPAQ, but I havnt tried it on the 8525
I dont think its MS bluetooth Vs Widcomm because the iPAQ 2790 uses Widcomm and the 8525 uses MS (I think) and the both behave badly.

Disappoining but unsurprising
Do the math:
It's an OS running on a puny 400 mHz processor trying to simultaneously mediate and transmit two separate broadcasts on a device that is really just a souped up 1st/2nd generation device. More importantly these aren't open broadcasts, there's likely some form of encryption in one that's run by the OS unless your AP is open. All the while it's also performing the phone function (unless you have that turned off). Frankly, its a wonder I get 5 seconds of sound
I have gotten some decent results from streaming mp3 radio to my headphones via 3G connection- which isn't totally dependent on the OS, but not since I upgraded to WM5; I also get great absolutely fabulous reception on my headphones when playing from the SD card, almost 10 meters range when I'm at the health club. So you take the good with the bad.

better A2DP Quality with BT 2.0 (EDR) ?

Hi!
Just want to know, if someone tested the A2DP stereo quality with Bluetooth 2.0.
With headphones from plantronics for example, there could be a better quality, couldn't it?
I mean, BT 2.0 can send the stereo signal in a uncompressed way, so there have to be a much better quality..
Annyone have experience or facts? Google didnt helped me
thx for reply

Old laptop = a2dp reciever for PPC stereo?

This may be off topic for the forum, but I'm wondering if I could throw some ideas around in the hopes that perhaps someone from here has done something similar and could offer suggestions.
I've got this old IBM thinkpad attached to my stereo system which I use as a streaming media computer for my music (obsolete laptop, but good for playing internet streams or media files on my home network over the stereo).
I very often attach my pocket pc (HTC Titan) as my music player to the stereo as well, usually using a portable a2dp receiver with a 3.5" port (i.tech r35, to be exact) to stream music wirelessly.
Problem with this is that I constantly need to charge the r35 adapter because it won't charge the battery while playing music (poor design choice).
The obvious solution, since my laptop is always hooked up anyway, would be to add a bluetooth dongle to the laptop and use it at a receiver.
I tried this, but sadly WinXP does not support the A2DP profile in its native stack, and I don't have a valid license for any of the third party ones (broadcomm, Bluesoleil, etc).
Is there a simple way to support a2dp stream receiving from this laptop? An open-source bluetooth stack perhaps?
The truth is, I don't really need *windows* on there for what I use it for, I would be open to installing a linux distro if it had a2dp support built in (and wasn't too complicated to install and use... I've got very limited linux experience).
What do you guys think?

nobody has any pointers?

Wouldnt it be easier to do via wifi? Better range and higher quality than A2DP too?

i've used my wizard to stream to my laptop before with just the native bluetooth stack on the laptop
i'm sure you could just buy a bluetooth dongle and sync it via A2DP that way

Download bluesoleil, it has an A2DP server you can use to send audio from PPC to the laptop.

Um... I'm not sure that you understood the concept here. First of all, when properly configured, a2dp is virtually indistinguishable to wired speakers when dealing with mp3 files (you lose a slight amount since it IS compressing the data, but not any more than a well encoded mp3). Second, range isn't an issue since I plan to control the music from the room I'm in (why would u want to play the music in a room far enough away that u can't hear it?).
Third, unless I haven't heard of a new Wifi audio protocol, I think what you're talking about is TOTALLY different. I stream music to my stereo from networked computers all the time, but thats not what I'm talking about here.
I use my ppc as my personal music player, and sometimes I want my playlist on the ppc to come out of the stereo system in my house. A2dp lets u do that by simply BEING IN THE SAME ROOM AS IT. I frankly don't see how WiFi would be an acceptable alternative to this since there is no audio transport support built in- its designed mostly for just networking.
I'd love to be proved wrong, so please share with me if I'm missing something here, but how would Wifi be better?
thenext1, I actually have bluesoleil, but its not registered to my device so its stuck on a 5mb trial version (5mb of info and it stops). I was thinking of something free / open source, which is why I thought about a linux option. if there is a free windows stack for A2dp, I'd love to try it...

This looks intersting I am about to try this bluesolei
What I'm looking to do is actually route calls to my laptop mic and speakers when my phone is docked in the cradle...
I'm thinking since this is the same principle that it can be accomplished?
Let me know if anyone has done this before...
it is kind of "off-topic" but i think it was relavent to post here because it deals with the same principles

It's not the same principle, A2DP is for hi-quality audio, you are trying to make the handsfree profile work.... It should work, since bluesoleil can also do that

Wow. You have got some aggression issues.
First of all, read through the entire post above and replace A2DP with WiFi and see what comes out. There is no advantage of using A2DP over Wifi if you have wifi on your phone. Set up a simple streaming server on your mobile then stream it over Wifi to your laptop. After the first configuration you run one application on your phone and press play in whichever media player you have on your laptop to start the music. Dead easy. Full quality, no reencoding or anything. Control the music from your PDA etc etc.
Not entirely sure what you are on about with the range? Wifi works perfectly if you're in the same room, what's A2DPs advantage? You dont have to stand 100 m from your stereo just because you're using wifi
Oh, and reencoded A2DP is _not_ indistinguishable from MP3s on normal speakers. Unless you mean laptop speakers. A2DP is a lossy encoding that is limited by the connection speed (and thus signal strength) which means that you have to be right next to the bluetooth receiver to get maximum quality. As you move away from the receiver the signal will drop, thus the speed will drop along with sound quality. Same thing happens with Wifi but the lowest connection speed over Wifi is still way beyond what you need to stream music at decent quality.
And.. ehm.. Both wifi and bluetooth are ways to transfer data, A2DP is just a protocol like FTP or HTTP. No magic there, Bluetooth and Wifi are basically the same thing but with different bandwidth and range capacities. In this case you'd use HTTP to transfer the music over Wifi instead of A2DP over Bluetooth, result is the same.

why isn't it the same principle?
my motorols HT820 headphones are A2DP and it has a microphone on them and i use it as a headset and to play music
...
BTW if you're looking for something free and linuxy why not use VLC over wifi
i'm almost positive they have a mobile client and it would def. be better than a2dp

I have to say I share the thread starter's frustration on this. Perhaps a little clarification is in order.
A2DP is far better suited to the purpose than a stream server on wifi in this case, because was simply designed to do exactly what Dishe is trying to do - connect an audio source to an audio sink without wires. Given the right software stack, all this should involve is a quick pairing procedure.
Streaming audio on the other hand, especially from a mobile device, is somewhat tedious - hacky at best, but certainly not "dead simple". You'd have to set up a stream server, probably third party and definitely not part of standard wifi installs. A audio streaming server on a mobile device could prove to be quite a resource hog as well. Attempting to this so in a time where bluetooth dongles (especially the made in china ones) that come with Bluesoleil go for next to nothing sounds like unnecessary fuss to me.
About a solution, I think picking up a cheap bluetooth dongle with Bluesoleil installed would be the most painless way to go. Linux and bluetooth don't exactly play nice from experience, but I've never actually tried to run an A2DP sink on it. You could do some reading on BlueZ, which is linux's standard stack and see if anyone else has had any luck.
Right now, A2DP sources are more common on PC stacks than A2DP sinks - people usually want to send audio out to a wireless headset or something instead of recieve audio - so google doesn't seem to be of much help. I'm currently trying to get it to work as well, and will test BlueSoleil within the week or so on a Windows computer and post back here if it works. Don't hold your breath, though.

[Q] Audio (music) over bluetooth

Hello,
I have a problem with getting Android music over LG HBM-220 bluetooth headset.
I can pair the headset normally with my LG GT540 mobile phone, and they work fine when i am making calls, but the audio (music) does not work.
Why is that so? Is there some application i need to install to transfer audio over bluetooth, or the headset doesn't work with audio?
Thanks for your time.

Anyone? Please reply if you know anything?

I don't think Android can do this out of the box, try searching around Google and Android market, because I am intrigued about this too.

I have the same problem, and Android actually suports streaming by bluetooth, the problem its that Swiftdroid (the Modded Ver.) dont support it. Im looking for a solution.

Audio
I think Swiftdroid only supports audio calls but not media playback. :/

Stupid question, but how good is audio quality over bluetootha headphones? I supose file with big bitrate dont stream in full bitrate. Or i'm wrong?

I think the Bluetooth technology on the LG GT540 doesn't support Enhanced Data Rates (EDR), so it will result in a lower quality.

Would seem that it does (I could'a sworn that it didn't... guess I never checked the specs sufficiently), however I have tried to sort out some kind of 3rd party Media->Bluetooth and have managed to get it to work... sorta, but the quality has always been damn horrid (not to mention it only ever works while the screen is on, and not locked). -- This may be due to the fact that SwiftDroid does not have native support for Media->Bluetooth and therefore may be missing vital library/module components needed to utilize Bluetooth EDR.
https://market.android.com/details?id=com.bedoig.BTmono <--- seems this one works now, streams *all* the audio to bluetooth and still works with screen off/locked. (however it may increase battery usage pretty hard, as it constantly streams to headset... even if it's just static!)

Well....i can use my headphones perfectly with Swiftdroid.....even the screen is lock or unlock.
And sound is....so goood!!
I play music over bluetooth and make/receive calls.
