The output and input quality is fine.
Unfortunately, however, the microphone to interference. About every two to three hours of use come over the microphone input language besides considerable noise with. Then there is always plugging USB Stick and restart Voice program. I've tried various communication programs, at all, the problem occurs.
In addition, the device turns constantly in a "disco stick" by the annoying LED just begins long time to blink until you here simply block pulls the stick and re-plugging.
I now give rather of 10 more and buy myself a stick which is hopefully more reliable.
