inaudible !!! a wired headset within 10 had done much better

This helmet comes into saturation as soon as there is music.

For avoided that other trick is done by positive comments. (Unless quality is super random)

Voila my tests

By adjusting the sound Pc mini helmet max:
A permanent low blows in the helmet are so dirty that it is unbearable. The channels are understandable.

By adjusting the sound to maximum headphone mini Pc:
The Standing breath in the helmet disappeared and the bass is so dirty that it is even more pathetic. The channels are understandable most of the time.
The sound quickly becomes full very quickly

The best made with the setting below
By adjusting the sound to maximum medium Pc helmet and VLC setting:
In VLC equalizer setting by 2 passes flat with a -17dB preamp !!!
The sound saturates much less (1 out of 2 instead of 100%), not too annoying blasts. the channels are still audible.
But is is super mega plattttttttttttt.

Direct returns if not trash.
