Review on Sony - C400 Wireless Behind-Neck In Ear Headphone White (WIC400/W) by Vanchay Sangkeaw Ice ᠌

Without quibbling, these headphones are excellent value for the money. The main benefits include a large battery, which at work allowed for two shifts to last 12 hours in music and headset mode while still having 50% of the charge left. They also frequently refer to the vibration motor as having "tobish energy," and the buttons' ergonomics can be felt even when wearing gloves. I originally purchased it for music, but as I started using it, I sold my previous headset, thereby killing two birds with one stone. similar item for my wife!
