Review on Sennheiser HD 4.50 BTNC Bluetooth Wireless Headphones Featuring Active Noise Cancellation in Black and Silver by Hideo Tsuchida ᠌

The wireless connection is stable, it works through two non-reinforced concrete walls with nooks and crannies, but open doors in the rooms. I read by “beep” when turning on each next track, nothing beeps for me. When you hold the volume button for a long time, it really beeps, but why hold it for a long time and it helps to understand that the adjustment is taking place, unless, of course, the listener's nerves are in order. At the end of the maximum-minimum, a special signal is heard that this is the limit. The control buttons, when you remember tactilely where it is, are comfortable and work well, it can only be inconvenient for very large fingers, but you can’t install “huge” buttons on the headphones. Nothing creaks when worn. Noise reduction dampens mainly low-frequency sounds, there is no indicator, but you can quickly determine by ear. In the instructions for ANC is written to hold the headset power button for 3 seconds, but you only need to press briefly to turn it on. on or off
