Thank you for viewing! ☆Please read my profile☆ I purchased this here about 3 years ago in "like new" condition (¥11,500). I used it at the training gym once every two weeks. Each use was about an hour long. It charges and works without any problems. However, there is some dirt on the charging case. See image ⑦. Please note that this is a used item, so no returns or refunds. What I will send: headset body, charging case, ear tips [SS.S.M.L], arc supporters [M.L], USB cable type C (USB AC adapter is not included from the beginning), instruction manual. I have wiped each item with a disinfecting wet sheet, but please refrain from purchasing if you are sensitive to this. There is no outer box, so I will pack it with bubble wrap and other cushioning materials. Thank you for your consideration.
