This item is a junk item. Due to a battery issue, the power turns on and off intermittently. I plan to re-examine it tomorrow. If you only want the charging case, you can purchase it now. However, if you don't want it even if the power doesn't turn on, please wait until after I've tested it tomorrow before purchasing. I believe the charging case is fine, but I haven't been able to verify it in detail, so please understand. Please consider this item with the understanding that it is a junk item and that there may be other defects besides those mentioned above. This listing includes the left and right earphones (+ ear tips) and the charging case. The items I sell may include used items, so please understand that I cannot answer inquiries regarding usage period or frequency. Shipping is included, and the item is priced affordably, so please refrain from price negotiations. Immediate purchase is welcome!
