Logitech Headset is not working

[donCORLEONE]

Helo!

I just bought Logitech Mobile Headset and tried to connect it with my PC. I am using microsoft BT dongle with Blusoleil software on it. I can find the headset as well as I can pair it with the pc, but when I start the connection, strange sound start come out of the headset for about 10 seconds, then the connection interrupts.
In the meanwhile, when the connection is active, there are no other sounds from the computer on the headset, as well as the microphone doesn't work.

Any soluitons?

Thanks!
