Review on Sony WH900N h.ear wireless headphones on 2 Wireless NC by Li Mei ᠌

- Build quality and materials. - Sensor in the earpiece. A very handy thing. - Sound. For me, it's quite excellent. There is nothing to compare with, and I do not consider myself to be a professional who hears on the verge of human hearing. Undoubtedly, the noise reduction makes its own adjustments to the sound, but in general, the sound more than suited me. - Shumodav. Handles external sounds very well. If you go to the subway, then you can listen to music at 30-40% volume. Works in several modes: 1) extinguishes external sounds 2) extinguishes external sounds + wind 3) so to speak "environment mode"; You can hear everything that is going on outside. - Comfort fit. On my head, the headphones sit quite comfortably and comfortably. - Autonomy of work. The battery holds up very well. The claimed 30 hours of operation without recharging is true. - Stable Bluetooth connection. I read reviews about the fact that the connection is lost. I didn't have that. I specifically tested the quality of the connection, both with a laptop and with an iPhone. Communication is stable at a distance of more than 10 meters. In addition, he went into the corridor, to other offices - the connection is maintained despite the distance of more than 10 m and the presence of 3-4 walls. The only thing is that I did not ate to the latest available firmware. Maybe with the new firmware there are interruptions in communication.
