The sound is surprisingly good. Well, of course, nothing for audiophiles, for games but more than adequate and the price fits. Now for the negative: Shielding against environmental noises nil. So when I set normal volume you can hear any problems nor the television or the like. With prolonged use, it is also very hot on the ears. This can be very uncomfortable over time.
I had what was bad from discounters to 10. The processing but none of the feel and the shield.
