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

After being worn for two years, one of the wires became damaged over the winter, and not long after that, the ear ceased to function. In temperatures below zero, wires will typically get a noticeable tan, therefore you will need to handle them with extreme caution. In overall, I found the headphones to be comfortable, however throughout the entire listening experience, I kept anticipating that the cord would snap. With all of its perks. The sound quality is excellent. They are designed to fit snugly inside the ear canals. When the battery was kept for an extended period of time, it was worn every day for three to four hours, and it was charged once every week or two. Some cons: When exposed to the cold, the thin wires that run from the collar to the earpiece turn a tan color. When I was speaking, my interlocutor did not hear me very well; thus, I needed to bring the bow near my lips, and after that, everything was good. At the same time, sounds coming from other sources are muted to a satisfactory degree.
