The transmitter sends music to the receiver in the next room, but the handset does not function otherwise. It finds the transmitter, says OK then nothing. I can hear the music, but to change songs I have to do it on my PC.
The Logitech StreamPoint application works with different devices including receivers and headsets. If you have problems with the application, then I recommend checking its configuration options. It's possible that the headset is not configured properly, or doesn't support song changing or any other operation related to the song management.
