I'm selling this because I haven't used it for the past few years, having used other products. I tested the battery life, so please check the photos. (iPhone 16, volume at about the middle of the bar) It lasted 4 hours and 19 minutes from a full 100% charge until it ran out. However, this is data from the time of testing, and there is no guarantee that it will play for the same amount of time after purchase. We will not accept complaints or returns regarding short playback times. I think it's easy to use if you install the official BOSE app. The charging port cover is detached from the main body. It never came off during use. Everything in the 2nd and 3rd photos is included. [Set Contents] ・Earphone body ・Eartips (L size only.
