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

The benefits of it include: In general, a regular sound, a considerable amount of effort: On trips that are more than ten hours long, I pass the time by listening to music and watching movies. Cons: Customers have voiced dissatisfaction with the audibility of their calls on occasion. Even if the wires turn a brownish color when exposed to the cold, this typically does not cause any problems.
