The Sandberg Headset converter is suitable to divide subscription form in a stereo sound jack into two mono streams. The audio quality does not suffer thereby, as far as I can tell. Similarly, the build quality is good and it does not dissolve or tear off parts. I have completely misused the cable and take up so in my microphone input of the computer against two signals coming from electronic components. Also it works flawlessly. So all in all a top product and also still low. 5 Stars.
