another device from Sony, which you do not know how to treat. on the one hand, several well-realized things, on the other, a lot of incredible jambs and an unreasonably high cost. compared with Bose - they have a better sound, although the noise reduction is worse. With its pros: - unexpectedly very comfortable, albeit full-sized. light, the head does not get tired - sit securely - pleasant to the touch - excellent noise reduction in the low and mid-low frequencies - hold charge very well - a really useful function of transmitting external sound - robust design, foldable - good case Has cons: - the sound quality is top three, whatever one may say, improvers. the bass is blurred to the point of potatoes. listening to music under normal conditions, especially electronic music, is not a thrill at all. come down on the street. on the cord the sound is full of feces - used a couple of times out of necessity - maximally castrated application: a lot of missed opportunities, a weak equalizer with five bands (!?). there is no way to adjust the sound transmission volume. you can’t turn off voice alerts, you can’t turn off voice assistant activation, which infuriates - bugs saving settings in headphones. I turned off speak-to-chat, but on working calls they simply cut off the sound to me several times as soon as I started talking. a special joke is that it is not always clear immediately. people answer you, ask questions, but you can’t understand what’s wrong with the connection - do not remember the last mode before shutdown - connecting to two devices is not working with two devices. only one can be used. - flaws in the autopause and wheelbarrow functions - false positives and skips - several times it happened so that they just turned off when fully charged - I turn them off in a conversation - the interlocutor hears very badly at any settings - cheap appearance and bad buttons. no choice of colors - very high price, even if these problems are not taken into account
