Hi, I am bishwo, I have successfully connected 2 stereo bluetooth headset at once by using software Bluesoleil.just installed the software and paired 2 bluetooh headset and connected. no any problems now. before I am also thinking that it won't happen. after large number of trials I have done it. I have also tried 2 bluetooth dongle at once thinking it wouldhelp. but single bluetooth dongle is enough to connect 2 headset at once and both sounding ok.
Tehat elvileg a Bluesoleil program kell.
