Super headphones, the quality for Bluetooth is one of the best, if not the best. It remains to add in the fifth version ipx4 and a normal microphone. Its pros: For the first time in 10 years, he changed Sennhesier and did not lose. The headphones sound great, the bass is frisky, but not oppressive, the high frequencies are bright. Everything that is written about noise reduction is true: it adapts depending on the environment, cuts off all extraneous noise, as a result, it is an unusual situation that you can set the volume slider to less than half and enjoy the music, because apart from it nothing else gets into your ears. 360 reality audio sounds just magical, it's a pity there are very few tracks in this format so far. By the time of battery consumption, I did not measure the exact time, enough for 3-4 days of active use. With its cons. 1) Five buttons are thrown on the right touch panel at once. As a result, in order to stop or resume playback, you need to hit exactly in the center of the cup. A trifle, but after Sennheiser's TW - uncomfortable and unpleasant. 2) Complete lack of protection against moisture. If sweat during a run is probably not so terrible, then rain or snow will most likely force you to put your headphones in a case. 3) With such a super-technological filling of everything related to sound reproduction, the built-in microphone is a C grade.
