I do not accept price negotiations. Wireless Noise Canceling Stereo Headset Model Number: WH-1000XM3 Color: Black Retail Price: 28,468 yen (tax included) Purchased new on September 3, 2021. All accessories, including the instruction manual, are included. The successor model, M4, had already been released, but I chose the older M3 because it was cheaper. I used it for a few hours after purchase and was satisfied with my first noise cancellation experience. After that, I didn't have many opportunities to use it, and I stored it carefully to prevent over-discharge. The box is still in its original plastic wrapping except for the opening, and I think it's in very good condition. The pairing has been canceled, and it has been initialized. Other important notes are also listed in my profile, so please read the comments carefully before making a purchase.
