These are the BOSE QuietComfort Ultra Earbuds with noise-canceling function. Bluetooth compatible. Purchased new from an electronics store around the end of last year. Used approximately 3 times a week for about 2 hours a day. Usage frequency decreased after that, and they have been in storage. Charging frequency was also low, so I believe the battery condition is good. Ear tips other than M are unused. They have been disinfected with alcohol. Box and accessories are complete. Please understand that these are used items. Bose Model Name: QuietComfort Ultra Earbuds Other Features: Noise Canceling Color: Moonstone Blue
