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

I took headphones, mainly for use at work as a headset, and at the same time for listening to music while working at a laptop. There are ordinary wired sensors, but without a microphone, and I wanted something close in sound quality, but with a microphone and without wires. After 3 months of operation, there was a definite opinion, which I decided to share. There are no complaints about the sound quality, they do not reach good wired ones, but if you are not an audiophile, then they sound very worthy, much better than various budget BT headphones. But on the software side, the headphones are very raw, as can be seen from other reviews. It is unlikely that what is described in the shortcomings is the problem of iron. And most likely this could be fixed with firmware, since the headphones themselves and the proprietary application allow firmware ates. But the manufacturer is in no hurry to fix anything and release an ate. In general, I would not recommend buying, at least until the existing problems are fixed.
