Purchase date: 2025/8/9 Used for about two weeks. There are no issues such as connection problems or noise that were present in the previous model. The new Cinema Mode feature has also been confirmed to be working. There are no missing items. I will include the purchase certificate, so the warranty should be valid until August of next year. As a bonus, I will include a case (excluding the carabiner). These are Bose QuietComfort Ultra wireless earbuds with high-performance noise cancellation. - Brand: Bose - Model Name: QuietComfort Ultra - Features: Noise Cancelling Thank you for viewing. #BoseEarbuds #BOSEearbuds
