I purchased this item used around the fall of last year. I have lost the instruction manual and box, but all other items such as the USB cable and ear tips are included. In preparation for listing, I have thoroughly cleaned the charging case and the main unit with disinfectant wipes. I have confirmed that it is working, and I believe it can continue to be used without any problems. The condition is not too bad and I think it is in a clean state. The YAMAHA TW-E3C is a pair of gray wireless earphones that supports Qualcomm aptX Adaptive and comes with a charging case and ear tips. - Brand: YAMAHA - Model Name: TW-E3C - Color: Beige - Included Items: Charging case, ear tips - Bluetooth Version: Qualcomm aptX Adaptive Thank you for viewing.
