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

The contacts at the arc could not handle it, but it undoubtedly lasted a long time as they slept after the son started to fall asleep naturally in them. Sony has reaffirmed its reputation as a producer of trustworthy, high-quality gear! Its benefits purchased for a teenage kid. He slept, ran, and lived there, but he did not swim (and that is not a fact). They lasted somewhat longer than two years, had decent sound quality, are pleasant to wear in the ears, and have a good microphone. With some drawbacks, button arrangement is intuitive. These weren't comfortable for me to wear while exercising because they either rescued me or smacked me in the back of the head with an arc during half of the gym workouts.
