Two USB rechargeable Bluetooth earphone sets, usable for approximately 12-15 hours. I'm selling these because I replaced them with new ones after using them for about three months. The ear tips have been replaced with new ones, and the main units have been cleaned. - Type: Bluetooth earphones - Charging method: USB port type B. - Button functions: Multi-function button, minus button - ON/OFF function: Blue light indicates power on, red light indicates power off - Usage time: Charging is complete in about 2 hours, everything in the images is included. Thank you for viewing. Reasonable price negotiations are possible. Immediate purchase is welcome, first come, first served. Prices will be gradually reduced, and will loop at the lowest price.
