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

Six months later, the contact in the wire of the left earpiece began to act up (you have to touch and bend the wire a little so that the sound appears again). It was annoying enough, but during this period I listened more to podcasts than music, so one ear was enough to not throw these headphones away at the first appearance of a problem. About 10 months after purchase, the sound in the left ear disappeared completely. I'm going to choose others. At the very beginning of use, there was a problem described by others with sound interruption due to interference, for example, in the subway, but they say this problem happens in all wireless headphones. After a while, this problem disappeared for me, although I stopped paying attention to short interruptions (in podcasts this is not as bad as in music), and there were no more long interruptions.
