Review on Sony WIC400/L Wireless Behind-Neck In-Ear Headphones, Blue by Athit Boonnoon PK ᠌

I've only been testing for 4 days. In principle, a good product for my money, so far I can only say one plus BATTERY really works 18-20 hours, loud sound but not enough to cover the noise on the street, sound insulation suffers. Too thin wires on the headphones, I hope they can withstand it, the holder for the neck has already stretched and dangles, which is also annoying. Let's see how it goes for another week, and then maybe I'll return back
