The main unit, one AtoC adapter, and the receiver are all included, except for the instruction manual. I don't think the AtoC adapter is usually necessary, so if you need it, please let me know in a message and I'll include it. I'm selling this because I've never used it after purchasing. The box is not included. Charging and pairing have been tested and confirmed to work. Retail price: 3198 yen. Purchased around July 2024. Although there is no instruction manual, I have included screenshots of the product page, which contains the same information. No drivers needed, just plug in the USB receiver.
