Audio-Technica ATH-DSR9BT wireless headphones, 2016 model. I purchased these new about 5 years ago for approximately 50,000 yen and used them occasionally, but I am selling them now as I no longer have a need for them. They are fully functional, including iPhone connectivity, touch controls, analog buttons, battery life, and sound quality. The ear pads (compatible replacements) and the headband (likely original) are worn, and the charging port cover is missing, but the metal parts and other exterior components are in good condition. If you are concerned about the ear pads, compatible replacements are available on Amazon for around 1200 yen. If you are unable to use Amazon, I can also procure compatible ear pads for you. In that case, the price will be an additional 1500 yen. I can add more photos, confirm functionality, and offer a price reduction if you are ready to buy immediately, so please feel free to comment.
