Here’s how you can find out if your Bluetooth headset supports A2DP:

1) First pair your Bluetooth headset with the Windows Mobile pocket pc
2) Go to “Bluetooth Settings” which should be under Start—>Settings—>Connections—>Bluetooth and tap on the “Devices” Tab
3) Your bluetooth headset should be listed over there. Tap-and-hold on it and you will get a context-menu that should list the following options:

Edit
Delete
Set as Hands-free
Set as Wireless Stereo

If you see the “Set as Wireless Stereo” option, your Bluetooth headset supports A2DP
