Is it these headphones click here ? I use these to listen to music from my pc. Surprisingly good quality sound when I got them working.
Not sure I understand the problem. The process of connecting a phone is very similar. Have you managed to "pair" the headphones to the computer? The pairing code is 0000.
My pc uses WIDCOMM software drivers for the bluetooth. Some cheap dongles use Bluesoleil drivers which I would avoid. They limit transfers to a few MB until you send them money.
The bluetooth interface should allow you to find devices in range. Select the headphones (BTS-PHF38), enter pairing code, select the service "stereo audio". When connected, the headphones automatically replace the pc's speakers for sound output.
