Thank you for viewing this product. This is a listing for a Technics EAH-AZ40M2 black true wireless earbuds, a defective item. Purchased from an electronics retailer around May 2024. I am selling these as I no longer need them due to the purchase of new earbuds. The earbuds themselves function normally and can be charged, making them suitable for those who don't use them for extended periods. Please be sure to check the condition of the product below, as this is a defective item. ◎ Product Condition ・The earbuds themselves have been confirmed to function normally, both in terms of function and sound. ・The case's battery is no longer able to charge, and the earbuds cannot be charged from the case when the charging cable is unplugged. ・The earbuds can be charged when the charging cable is plugged into the case, so they can be used without any problems for short periods of about 3 hours when you are out and about. ・Therefore, this product is recommended for those who have lost their earbuds and only have the case. ・All included cables and ear tips are present, and the ear tips are almost unused as I was using ear tips from another company. ◎ Notes on the product ・The product includes everything shown in the photos. ・Please understand that this is a junk item before purchasing. ・There are scratches and stains from use; please see the product photos for details. ・The earbuds and case will be disinfected with alcohol before packaging. ・I am a non-smoker. ・Price negotiations are possible, but please provide a specific desired price; we may not be able to meet your request depending on the price. ◎ The following are important notes; please be sure to read them before purchasing. ※Please confirm the product description before purchasing. ※Due to the nature of the item being a junk product, we cannot provide a warranty, so we will take the utmost care, but we cannot accept returns for damage such as stains that may occur during shipping. ※We cannot accept returns or claims after arrival or use. ※We do not accept questions after purchase.
