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

The sound is really good, and the soundproofing is sufficient; when it is turned up to a comfortable level, it is impossible to hear anything from the outside world. If you do not pull the wires too tightly, it will appear as though there are no headphones on and the music will play inside of your head. The headphones are designed to fit snugly in the ears without being noticeable. This is both terrifying and exciting at the same time. They function for a considerable amount of time; I wasn't able to precisely estimate how much time they provide, but it's plenty for my needs. At this point, the merits come to an end. After using it for a few months, the control buttons started having issues, such as the volume and pause buttons not working properly at random intervals. They did not correct themselves even when the headphones were turned off and on again, but in general, they were able to function whenever they desired. And since this is a significant drawback for me, I decided to grab a pair of headphones so that I wouldn't have to reach for my phone yet another time. In addition to this, there is not necessarily a connection. Because of this, switching from one device to another can be a very time-consuming process. If you have more than one pair of headphones, none of them will function properly because each pair is bound to a specific phone. Overall, I rate it 3 stars.
