I bought a promotion in Amazon for 24,999. The most expensive ears that I bought. Generally light, wear for 9-11 hours. noise reduction is excellent, in comparison with senhi 4.50 and bose comfort 35 2. wind noise is extinguished by 70-80%, voices are also crushing, but they are heard as if they are on the other side of the room. the sound is simply no for 29,999. 4.50 sekhni are much better in sound, juicy not covered up ! IT'S MY OPINION ! a sensor that is useless with the slightest condensate. I listened to flac on sbc, the restriction was lifted. there is also ldac. without wires, did not buy for this. the sound is deaf, as if the speakers were wrapped with a film, I canโt stand the equalizers. after 8 days, something began to click in the right ear when walking, turning and tilting the head, and even when you gesture with your hand. and if you listen further, it starts to skip sounds, the noise reduction of the right ear drops by ~ 60-70%. handed over under warranty. for 30,000 only because of the ease of construction and sound insulation. not mine.
