Skullcandy headphones. This is the Crusher Wireless (model number: S6CRW). The color is black. I purchased it on Mercari four years ago. There are no box or accessories, only the main unit is for sale. After purchase, I used it for about a year with little frequency. After that, I stored it, and I have confirmed the operation for this listing. The heavy bass unique to the Crusher series is still present, and the headphones will shake firmly when the bass is turned up. I listened to it after a long time, and honestly, it was quite good, and I hesitated to sell it for a moment. There are no problems with Bluetooth connection or sound output. The ear pads show signs of aging and have a used feel. There are also minor scratches due to use, so please purchase only if you understand the condition. Please understand that this is a used item before purchasing. If you have any questions, please feel free to comment. I will clean it simply before packing.
