★Please read the entire description carefully as this is a defective item★ 【Defective Item】 ambie sound earcuffs AM-TW01 White Box, instruction manual, and all accessories included Purchased from the official website in October 2021 Used only indoors. Used for about a year. After that, I didn't use them much, and when I checked the operation recently, the left earphone wouldn't charge and I couldn't hear anything. Also, when I removed the cover (socks) to check the operation of the left earphone, I accidentally tore a part of it. When I took pictures for the listing and looked closely, I noticed a slight verdigris (green discoloration) on the charging metal part, only noticeable to those with good eyesight or when magnified. I tried charging it with the case of another ambie I own, but the left earphone didn't respond. During pairing, the left earphone doesn't light up and doesn't respond, only the right one does. The audio can only be played from the right earphone. While the earphones are in the charging case, the orange light sometimes stays on for a while and then turns off, so there may be other problems besides the left ear not working, such as the battery condition. (I apologize that I don't have the ability to investigate and explain.) The warranty period has expired and I can't fix it myself, so I'm listing it as a defective item. If there is anyone who can fix it themselves or needs parts, please consider it. ★----★ I do not offer reservations or holds. Immediate purchase is welcome! Thank you. When packing, I may reuse packing materials in good condition. Thank you for your understanding. I have checked as much as possible, but this is a home-stored item, not from a store, so it may not satisfy those seeking perfection. I would appreciate your understanding. ★----★ - Brand: ambie - Color: White - Accessories: Charging cable, instruction manual - Design: Fits the ear shape - Charging terminal: Metal contacts Thank you for viewing.
