Bose QuietComfort Earbuds II, black, with noise-canceling function. Purchased from the BOSE official website. Due to an initial defect, the product was exchanged for a new one on July 16, 2023. Since then, it has been working without any problems and has been used for about 1-2 hours daily during commuting. It can be used for about two weeks on a single charge, and the battery has never run out, so I think it can still be used for a long time. However, there are some scratches because I dropped it once. (I will also include photos of the scratches, so please check them.) I will also include the unused ear tips that came with the replacement unit. There are no particular problems, and it is in good working condition. Please refrain from purchasing if you are a perfectionist or if you are looking for a perfect product, as this is a product that has been handled by a person once. - Model Name: QuietComfort Earbuds II - Color: Black - Accessories: Charging case - Noise-canceling function: Yes - Brand: Bose Thank you for viewing.
