Deep sound with good detail. Familiar compositions are revealed in a new way. I tested the microphone in a working car with not the best sound insulation at 80 km / h with the windows ajar - the interlocutor hears me clearly and confidently, sometimes asks if I'm in touch, apparently there is deep silence in the receiver while I am silent. The connection holds confidently - he moved away from the phone to the next room, through two doors, concrete and 10 meters there are no breaks. Noise reduction and transparent mode work quite well. They sit comfortably, do not fall out. The declared 5-6 hours actually work, but with the noise reduction turned off or the transparent mode. When you turn on one of the modes, the operating time is reduced to 2.5 - 3 hours. The shape of the ear pads is oval, you will probably have to look in China. Excellent ears - BMW in the world of headphones)) Of course there are questions, but they are not critical at all.
