※ This listing includes the charging case and the left and right earbuds. There are no other accessories besides the ear tips currently attached. There is a similar model, the HA-A10T, but this is the 11T, the successor. The battery life is doubled, and the performance has been significantly upgraded, including a review of the connection method. There are some scratches and signs of use commensurate with age, but the condition is not bad for a used item. If you are looking for a product in unused condition, please consider a different item. Sound output and left/right balance are not a problem. The multi-function buttons also work normally. There is no noticeable deterioration in battery life, and I think you can use them with plenty of room for general purposes such as commuting to work or school. I cannot guarantee this, but I hope it will be helpful in choosing a product. Please understand that this is a used item before purchasing. If you have any questions, please contact us before purchasing.
