Thank you for viewing. This is the Sennheiser HD820. Purchased new in March 2024 from e-earphone online store. Used less than 20 times, for less than an hour each time, so it's in excellent condition. I used it with the included balanced cable. The other analog cable and the manual are unused and unopened. As shown in photos 11 and 12, a part of the outer box was accidentally slightly torn upon opening, but other than that, I believe there are no noticeable scratches or stains on the headphones themselves. Although it is in excellent condition, it is a used item, so please understand that it is non-refundable and non-returnable. I have kept it stored in its box since listing it. As of November 11, 2025, the Amazon price is 290,000 yen. - Model Name: HD 820 - Country of Manufacture: Ireland - Cable Type: Replaceable cable - Color: Black - Audio Quality: Supports high-resolution audio
