Thank you for viewing. This is the Technics EAH-AZ40M2 true wireless earbuds. I used them for about a month. Operation has been confirmed, and you can use them without any problems. I haven't used them much, and they are in good condition, but please understand that they are used items before purchasing. They have been lightly cleaned with an alcohol wipe. [Included Items] ・Main unit (left and right earbuds) ・Charging case ・USB cable ・Eartips (S/M/L) ・Instruction manual ・Outer box I will pack them carefully and ship them. Thank you very much.
