Thank you for viewing. This is a wireless headset sold on Amazon for 8,999 yen. It has been stored at home unopened, but since I've decided to use an NTT Sonority headset, I'm decluttering this one, still unopened. I thought I could offer it to someone who wants a good one, such as for working from home.
