The weight of the product (headphones only) was listed as approximately 180g in the search results, so the remaining approximately 120g is likely the weight of the accessories and packaging materials. (Please refer to the 4th photo) Lightweight wireless headphones with Bluetooth connection ・Brand: audio-technica ・Model: ATH-S220BT Please refer to the 3rd photo for an overview and features of the product, as they are listed on the box. This was a gift I received around late August. Since I already have one, I am selling it as it was received, so I did not "purchase" it. Please note: ・"Warranty card enclosed" *A receipt or proof of purchase is required for repairs. However, since this was not purchased, there is no receipt or proof of purchase. ・When checking the contents (including accessories), I damaged a part of the outer box and repaired it with tape (see photos 6-7). I apologize for any inconvenience. I would appreciate it if you would consider purchasing after understanding the above. If you think the repair means it's not "new," that's correct, so please exclude it from your consideration (the main unit and accessories are unused). I will ship via Takkyubin Compact. Thank you for viewing.
