Micro good. He is recognized as a USB sound card, microphone input with output recess and where you can connect headphones to the microphone by a mini jack. The big plus point is that the volume of the audio output can be controlled by a potentiometer. Very convenient to finely adjust the sound.
Testing on Mac and Playstation 4 where the sound of the console can be deported.
Negative price and footprint. But really disappointed.
