this helmet is what I wanted: a helmet clear and true sound. It is very comfortable, it is supports several hours without any discomfort. This headset is quite demanding: all defects sounds degraded compressed formats (mp3) agree. As much with cd or listening flac pieces is very nice, as some tracks are unpleasant because of the lack of readily audible quality with hd595. Aesthetics is successful. I personally rediscovered some tracks with this helmet. Flaw: there is a jack / mini jack adapter supplied essential for using the helmet on all devices with a mini jack output. So the final decision is quite impractical (taking too long). The helmet is open, I do not recommend it for noisy environments. Also the people around you can hear headphones.
5/5
PS: small addition, the supplied stand is very convenient.
