The headset works well and I haven't used it much because I don't play games a lot; months can pass without me playing. The cable has a problem only, but the headset itself works 100%. This is usual for Sennheiser headsets, so it's not a defect specific to my headset. You can buy a replacement cable, and I've bought it twice before because the previous cable got damaged with use. So, you can buy a cable and it will work normally. I've attached a picture of the cable from Amazon.
The headset is expensive, and the clarity and quality of the sound are truly unparalleled. Being open-back allows you to easily hear external sounds. It's very light on the head and comfortable.
The reason for selling is that I want to buy a wireless headset. Also, when I stopped playing at my PC desk and started playing on the couch, this wired headset isn't suitable for the couch. I also no longer care about sound clarity and quality; I just want to play.
