The "spkVolume" key can be tweaked for louder sound from your headset. I believe the default is 8. I would only go up in small increments, because some BT devices are sensitive to this setting. I believe you need to soft reset each time you change it.
Edit: I just tried changing mine, but MSVC didn't like it. Had to revert back to the default. Not sure why, but this tweak worked fine in WM5...

This didn't really work for me. BTW, MSDN indicates that it should be HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Au dioGateway\
SpkVolume but anyway, thank you since I searched off your suggestion. I tried 8, 12,16,23,40,50,255 and they all sound the same. Soft-resets in between each number I tried.
Now I might be imagining things but the last value I tried was 0x1F ( = 31 in decimal) and it seems to be sounding slightly louder. But I think it's just my mind ...

So you're saying on helmi's WM6 rom you need to unpair and repair the device EVERY time you're going to use BT? That's quite impractical (and vulnerable: since the bluetooth key can be generated off the pairing data exchanged between the two devices; and anyone can listen to the pairing messages over the air).
Talking of vulnerability,
MSDN mentions that to enable encryption we need to set HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Au dioGateway\Encrypt as 1
I noticed it wasn't present, meaning the conversation between BT and headset is in the clear. I've enabled it and haven't noticed any quality degradation or any other problems.
Ok, now back to the bluetooth volume problem ...
