I've been using these for about six months. The sound quality is excellent, and I really liked them, but my living situation has changed, and I don't use open-ear type headphones much anymore, so I'm selling them. There are no issues with the appearance of the main unit or the battery condition, but please understand that these are used items before purchasing. The cable and outer box are not included. This is a sale of the earphone本体 (left and right) and the charging case only. They will be shipped with waterproof packaging. Reference price: ¥39,600 (tax included) Please ask any other questions in the comments. Bose Model Name: Ultra Open Earbuds
