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

The size of the ear pads was expected to be larger, like that of "stationary" senkhs, but in reality the headphones are quite small, and in order to fit the shells in them, you have to perform additional manipulations. The size of the headband could be a little larger, now the headphones are back to back on a large head. Management is really confusing at first. The volume is a little bit not enough, at least on the computer, on the phone it seems to be enough. The android application eats up the battery, so you don’t have to rely on it much, namely, the equalizer that is there. The microphone strangely amplifies the surrounding sounds. On the one hand, this is good, because your voice is amplified, but at the same time, for some reason, even what you have not heard before becomes audible. It's a little unclear how the headphones are reconnected to the device. That is, for example, Marshall headphones, even if they are turned off, then they themselves are connected, no need to press anything. But 450BT is somehow wrong, in any case, when you use two devices at the same time, you need to hold the button for 4 seconds.
