Used to connect an amplifier and a microphone on the common output of the dock my laptop (Lenovo 440P) not working or on the station, or connected directly to the notebook. So I returned. To note, none of the three strands of this type that I tested worked, so it is possible that the problem comes from the PC. The cable used is particularly fine, which leaves nothing to portend good regarding the strength or quality (the shield should be minimal).
