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

Got pros: I have been using it for more than a year, I bought it at Dr. Head - I chose from 8 options, including the marshalls that I was originally going to buy. In general, the purchase is completely satisfied - the sound is good, the battery lasts a VERY long time. I really liked the panel on the headphones themselves - you quickly get used to it, each task has its own button with a unique tactile feedback, so it's impossible to confuse them. Has cons: There are several disadvantages 1. In headphones, it is possible to connect via a wire and sometimes IT SHOULD be done (I’ll tell you when below), this wire is unusual and the head that is inserted into the headphones has grooves, while the headphones have protrusions that you need to get into with these small grooves and then rotate to lock. First things first - it's tritely difficult to do - the protrusions and grooves are very small and I didn’t succeed from the first ten times, secondly - it’s not clear why such a complex system is needed at all - why fix the wire in the socket, so that it would vomit if you caught on some any subject? 2. When noise reduction is turned on at low volume (or without it at all, a little noise is heard, right at the border of audibility). This does not interfere with listening to music, since against its background it is not audible at all! But if you want to listen to some ASMR at night, then it becomes very important. But this is treated if you connect via wire - in fact, this is the only option why you need to connect via wire at all! 3. When the headphones are discharged, they begin to report this in a robo-female voice every time the headphones do not play music, I could not disable this "useful" feature.
