Panasonic RP-HTX80B Brown Purchased new in 2022. I believe the usage frequency was about 10 hours a month. I am selling these as I am replacing my headphones. Detailed specifications can be found on the manufacturer's website: https://panasonic.jp/headphone/products/RP-HTX80B/spec.html Used regularly until 2025/10/21, and there are no problems with pairing, sound output, or charging. The ear pads were replaced with new ones in March 2025 (though they are not genuine). The headband has peeling, so I used a generic cover. Everything in the photos is included. I will ship it with the generic cover attached. Thank you.
