No breath, the sound is perfect and quite balanced with a low dominance as in any home theater system. The dynamics of this helmet is simply impressive, it automatically turns on when you put it on the head and turns off when it is folded. The multi-channel decoding is very honest, without asserting a true home theater system 7.1 or 9.1, the sounds are located in space relative to the scenes with a light placement on the back a bit too (you have to see the settings), no delay between sound and image. The bass is punchy and are worth a good subwoofer. Warning, the noise level can be quite high because several times I thought I lost my eardrums, consider lowering the level after a listen. Really ideal for enjoying home cinema sound without disturbing its neighbors.
