These are closed-back headphones from the renowned German company, Ultrasone. They feature precise spatial representation thanks to their unique S-logic technology and are designed to be gentle on the ears. The accessories, including spare ear pads and a storage bag, are all included, I believe. The spare ear pads show some signs of use, but overall, the headphones are in good condition, and of course, there are no performance issues. If you purchase these along with other musical instruments or audio equipment I have listed, I will offer a 5,000 yen discount on the total price. Please let me know in the comments section.
