Being in search of a helmet with a sound is pretty good and demanding music lover, I try several helmet in several specialty store, the Sennheiser Momentum, InFocus, Sony and other parrot. I just got it and frankly you can go there except for those who do not like the bass a little support, the sound is clear, whether medium or low pitched well despite the present this one does not cover the rest of the spectrum, a pure delight for the listener of pop music, rock etc like me. Lappairage in nfc works flawlessly on my note 2 despite its leather pouch. the range is also good about 10m, excellent sound insulation, you listen to mp3 in 320kb or flac (even better necessarily) the sound is like and frankly you are bluetooth (20hz to 20khz) or cable (4 40000hz to) the difference is imperceptible and it frankly well done Sony. Namely, on the sony store site right now there are 20% on this helmet that just came out and put back to 159 euros (before I wanted to take the mdr-1rbt). Ultimately certainly not worth having sour c momentum could also listen to it for him but he has the price, the wireless, the quality of sound as well as its weight (just over 200g) that once you forget on his head. So in the end quality / excellent price, to tell you for the moment the only fault I find is when it lenlève the headphones should have this bent the other way in order to put the headphones flat directly without turning on itself, a detail.
