Thank you for viewing. Purchased around March 2024, I used these headphones only 1-2 times a week at home for short periods of music listening. However, I haven't used them recently. I've only used them outside a few times. They are already packed, and I have cleaned the headphones with alcohol. They function without any problems, and both noise canceling and Bluetooth connections work perfectly. The appearance is also clean, with no noticeable scratches or stains (there are only minor scuffs if you look closely). All accessories are included, such as the box, cable, and instruction manual (※Warranty card is missing). ⸻ ・Lightweight and comfortable for long periods of wear ・High-quality sound and natural noise-canceling performance, typical of SONY ・In near-new condition, and in excellent working order ⸻ Reason for selling I am selling these because I have started using different equipment. ⸻ I have taken good care of them, so the condition is very good. I would be happy to sell them to someone who understands that they are used. Series: WH Series Model: WH-CH720N Other: Noise Canceling, Wired/Wireless Dual Use
