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

Leaving the house without my headphones is the same as not putting on my watch or picking up my phone. This occurs no more than once every six months, and they are always with me when it does. I have been wearing headphones for the past year and a half. The control buttons have a very pleasant feel to them and do not leave any marks on the neck. When it's freezing outside, the best thing to do is talk on the phone while wearing gloves and keeping the device in your pocket. About the worries that small wires might do something harmful, let it be known that if they are worn properly, they won't. Do not wear when the weather is cold because the wires can crack from the cold. This actually happened today, and the sound stopped coming through the right earpiece.
