So yes it is a very good helmet, with a value almost unbeatable prices. But there are "but". First I find it really very large and a bit heavy, it really surrounds your entire ear and more. However I am wearing glasses and I find that after long use it makes me less pain than other headsets I have used. The other big problem is at the level of sound quality. While it is certainly bluetooth but I find that compression artifacts are really important, and when we focus above it quickly becomes unpleasant. The ergonomics of buttons placed around the edges also bothers me, but may be it is just the time to learn their location. Last point: long battery life (about 6,7h) but we regret the fact of not being able to load the playing. Oh I forget falli, IR-DI-CULE size cable supplied with for charging. Congratulations Sony
