I'm selling these earphones because I've replaced them. I've confirmed that they work, including Bluetooth connection and all buttons. They have noise-canceling functionality. However, they are several years old, so there is a possibility of age-related deterioration. Included: Main unit, earphones, charging cable, replacement ear tips, instruction manual, quick start guide I will disinfect and clean them before shipping. I do not accept returns or refunds after purchase, so please understand that these are used items before purchasing. Thank you.
