This is a set of two COTSUBU for ASMR 3D earphones. The earphones in the box on the left were used a few times at home after purchase. They have not been used outside. I think they are in good condition with no scratches or stains. The earphones without a box on the right were given to me by a friend because they stopped using them, but I ended up not using them either. These also have no noticeable scratches, but they do show signs of use. Both of these were likely purchased and used about a year ago and haven't been used for a long time, so there is a possibility that the sound may stop working in the future. I checked them a while ago, and both occasionally had one ear that was difficult to hear, but it wasn't very noticeable. However, if you are concerned, please refrain from purchasing. The ones with the box come with the instruction manual, charging cable, and different sized ear tips. Also, the charging cable and ear tips are unused because I used others. The ones without the box have none of these. Only the main unit is included. Also, to prevent swapping, returns and refunds are not possible. These are used items purchased and used quite a while ago, so please do not make claims such as "the sound didn't work" or "it was scratched" upon arrival. If you are concerned, I can add photos if you comment, so please feel free to ask. Please purchase only if you understand. I would like to sell them together as much as possible, so separate sales are negotiable. - Brand: AG - Model Name: COTSUBU for ASMR 3D - Bluetooth: Supported - Charging Method: USB-C
