The ratio of price and quality is very pleasing, I will repeat the purchase.

There is nothing to compare noise reduction with, the first time I use something like this, it just is. The lawn mower outside the window does not interfere at all, but somewhere in the background you can hear it. The sound quality is subjectively no worse than Marshall Major 2 and Sennheiser HD 380 pro. They are assembled from plastic, but the reliability is like that of other senkhs, that is, they should last for many years even without thrift. How they work on the wire is not very interesting., But there is a wire, when you stick it in, the bluetooth turns off and the blue light comes on.

Some complain that they often hear the voice reminder "So many hours left." So, this reminder occurs only 2-6 hours before full discharge. That is, in general, it is quite reasonable, if you have been using headphones for 28 hours, and they are about to be discharged, start warning in advance.

Pros

The sound quality is excellent (at least when running aptx-HD); active noise cancellation is not an empty word here, it is really noticeable; connect two devices at the same time, switching between devices is fast; long battery life and charging in 2 hours; The microphone is quite good, the interlocutors hear well during a conversation.

Cons

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.
