Thank you for viewing. This is the SONY WH-XB910N headphones with deep bass and noise cancellation. From today until January 4th, the price is reduced from ¥7,700 to ¥6,500. Features: Noise Canceling Characteristics: EXTRA BASS Battery Life: 30 hours Model Number: YY2951 I purchased these about two years ago, but I am selling them because I bought new headphones. The items included are the headphones, an earphone jack, and an earphone jack. The ear pads and headband have deteriorated, so the ear pads have been replaced with non-original ones, and a headband cover has been attached to the headband. (I did both of these myself) Also, as shown in the 8th photo, there is damage to the "Y" in "SONY" on the left side. There are no other issues with the functions or performance. Please check my profile before purchasing.
