I've got a splendid headset for my computer and I want to use it with my phone. The connection between headset and the PC is via USB 2.0. I wonder if it is possible to connect your phone to the computer and use the PCs' headset?
You can connect via Bluetooth and play music from the phone and make calls. By USB un can only use Computer Internet Connection.
Edit: Sorry I think I misunderstood what you whant. Since you can connect Windows Phone in PC via bluetooth I think you can use PC headset instead of PC speacker.
Sorry, but that isn't going to work. The audio is only delivered over the headphone jack; not USB.
Maybe you can find a USB to 35mm headphone adapter, and try that. I can't promise it would work, but is should be at least worth a try.
