Review on Sony WIC400/L Wireless Behind-Neck In-Ear Headphones, Blue by Jeong Hoon (Kim) ᠌

I cannot comment on the sound quality, in my opinion it is adequate for such a headset. But I'm not a music lover. Got pros: The headphones are very comfortable, I almost never take them off. Good soundproofing. You can listen with one ear without worrying that the headset will crawl under your jacket and pull your ear. The battery life is very long, but it also takes a long time to charge. Cons: Sometimes communication is severely disrupted near public transport, up to the loss of connection. The rocker is harsh, under a down jacket it can cause a slight inconvenience. During charging, they turn off, so you won’t be able to walk with an external battery.
