muốn nghe đc nhạc thật sự stereo thì máy và tai nghe phải hỗ trợ chuẩn BT A2DP
1 trong 2 cái có thì cũng chỉ nghe Mono mà thôi, phí tiền
O2 series cũng có cách test và up lên A2DP nhưng hình như chưa ổn định và khá rủi ro

This is my experience using a HP bluetooth stereo headphone bonded with an O2 XDA II. I use Wincom 1.5 Build 2000 from "dtktvu". So far the setup has worked very well. After having used the setup for three weeks, my impression is as follows:
1. Connection with headset is very stable
2. Stereo sound is clear, quality is quite superb really.
3. So far this setup works only for music, it does not work together with bluetooth headsets (if you happen to have one). This means that you can not use your headset at all while using the headphone.
4. The only inconvenience is that if there is an incoming call during song playback, the music pauses but there is not any other audio warning. On the screen you do get a warning that there is an incoming call, though. So in my case, while I listen to music, if I hear a sudden pause then I know that there is an incoming call and act accordingly. Now, let us come to the next point....
5. You have to use Windows Media Player as the player for point 4 to happen. I am not sure how the setup will react to incoming calls with other players such as Winamp, GS Player etc..
6. Battery life is quite good. I get about 6-7 hours of playtime from the headphone.
Now, if only someone will update this Wincom Driver further so that it can work together with bluetooth headsets, then we will have the best of both worlds... Maybe donations from potential users to provide incentive to some expert out there.

You may need this key as well
[HKEY_LOCAL_MACHINE\Services\BTIcon]
"Dll"=""
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\Transports\BuiltIn\3]
"driver"=""
end.................
\Sorry I don't have time to make a cab file for this, however installing it should be simple, similar to my post on the first page:
I've managed to sucessfully installed WIDCOMM 1.5.0 build 0801 using the latest BTTrayCE.EXE. Headset bonded and connected OK but does not work yet (I'm still working on it). Here are the instructions:
1. Backup your device, in case something goes wrong.
2. Uninstall all BT tools (i.e. BluetoothGPS, BTTools, any previous version of WIDCOMM BT)
3. Rename your BTCEIF.DLL file in \Windows folder to something else, such as BTCEIF.DLL.BAK, then reset your device.
4. Copy all the files from mamaich's archive to \Windows (DONOT replace BTTrayCE.EXE file with the one in 'working_BTTrayCE.EXE' folder otherwise your headset won't connect. There are 3 files not needed, which are registry.reg, fixes_after_registry.reg, _____mxip_misc_100.rgu so you don't need to copy these to \Windows folder). Make sure all the files are copied OK.
5. Import the registry that I've attached here.
6. Copy BTTrayCE.lnk file attached here to \Windows\Startup folder.
7. Reset you device. You should have 1.5.0.0801 working!
Now, I'm still investigating why XDA II did not redirect all sound to the headset even though now it's connected OK. Can someone please send me a whole HKEY_LOCAL_MACHINE registry key of a HP6315 or DELL Axim, together with 2 files AudioGW.DLL & BTPWR.DLL from those devices?
Cheers,
