I've used various headsets and earphones, and since I only used this one occasionally, I think it's in good condition. I checked the operation, and the volume dial doesn't work well. I usually adjusted the volume with the dial on my keyboard, so I didn't notice it, but otherwise, it works without any problems. I recommend it to people who use it in a similar way. Regarding sound quality, I think it's quite good for RAZER. It costs around 36,000 yen, so if you don't mind the volume dial, please consider it.
