Very good but uncomfortable

Technically, it's perfect:
+: No wireless outage
+: The bass very present with the opportunity to set Surround / Hi-Fi made it though is worse than the standard mode
+: You can walk all over the house (50 m²)
+: You can use it for music smoothly, very well balanced.

By cons, it's very uncomfortable, the arch serves as the head at the top after 30 minutes of use. In addition, you will be forced to use the optical cable, not the jack, why? Because a background noise (snow) persists and very pronounced. Optical unbearable but no problem.

So I return to take on a more comfortable helmet in my use (+ 3 hours / day)
