Wireless earphones with simultaneous interpretation function for smartphones. This item is unused, so I don't know how to use it. This is a prize item, so please only purchase if you understand that. Also, an activation code card is included. The activation code can only be used once, so returns are not accepted after purchase. The box will be flattened and removed from the plastic case, and then wrapped in bubble wrap. The plastic case will not be included (only the main unit, the flattened box, the instruction manual, and the activation code card). If you want the box as it is without removing it from the plastic case, it will be an additional 500 yen. Please purchase after understanding the above.
