Review on Sony - C400 Wireless Behind-Neck In Ear Headphone White (WIC400/W) by Hien Kent ᠌

After another half a year, the contact in the wire of the left earpiece started to behave erratically (you have to touch and bend the wire a little so that the sound appears again). It was bothersome enough, but during this time period, I listened to podcasts more than music, so the fact that only one ear worked was sufficient to convince me to keep using these headphones even after the first sign of a problem appeared. After approximately ten months from the time of purchase, there was no longer any sound in the left ear. I'm going to go with other options. Others have reported that, at the very beginning of use, there was an issue with sound interruption due to interference. For example, this issue occurred while riding the subway; however, they say that this issue is common to all wireless headphones. Once some time had passed, I was no longer experiencing this issue, despite the fact that I had stopped paying attention to brief interruptions (although this is not as problematic in podcasts as it is in music), and there were no longer any lengthy breaks.
