Review on Sony WIC400/L Wireless Behind-Neck In-Ear Headphones, Blue by Airi Ohtsuka ᠌

The sound is excellent, soundproofing too - at a moderate volume you can not hear the outside world. The headphones sit firmly in the ears, but imperceptibly - if you do not pull the wires hard, it seems that there are no headphones, and the music plays in your head. This is both frightening and delightful. They work for a long time, I didn’t measure how much specifically, but it’s enough for me. This is where the merits end. After a few months of use, glitches with control buttons began - the volume and pause buttons periodically stopped working. They were not corrected even when the headphones were restarted, in general, when they wanted, they worked then. And for me, this is a big minus, I took these headphones in order not to reach for the phone once again. It also doesn't always connect. It takes a long time to reconfigure from one device to another, because with several headphones they refuse to work - they will be tied to one phone, but not to another. Overall, I give it 3 stars.
