Sound. Well, it is clearly better than in wh-ch710n in absolutely everything, since there is no sound at all, so, some kind of garbage. In the purity of low frequencies, they directly lose very clearly to the same MDR-XB950AP, but also at a very decent level (on Unraveled Lorn in flac, they whistle and fart from a certain volume level, which the 950AP does not have). and the quality of sounds transmitted by headphones in transparency mode. Sturdy design (the guy on the doctorhead channel on YouTube almost folded them into a ram's horn), the case is included (soft, but rather tight) Touch control is quite interesting to try out after various joysticks (a fierce reference to Marshall) and buttons. The plastic here, of course, is a little less steep than in thousandths, but it is also good, especially since its texture is rougher, which I was much more driven in than slightly slippery thousandths. By the way, the design of this and the older model is very similar, as, in fact, the convenience of landing (kaaaayf)
