Breath

The adapter is very small and has paired carefree. By cons there is a pretty strong breath when the audio stops and permanent breath but lighter when playing, especially at low volume and input jack.

I tested the output jack of a Mac and the output jack of a TV, breath was present in both cases. But no breath at the USB audio adapter in use. It is easy to hear the breath just after a break during use, or if the volume is low.

By setting the volume loud enough, we hear less the breath and the quality is more than sufficient for use TV type.

NB: the entrance automatically switches to the jack as soon as it is plugged
