USB-connected black over-ear headset with microphone. It's the EPOS PC8 USB. Purchased on Amazon in August 2025 for 4950 yen and used a few times. I bought it, but the headset I was using before was more comfortable, so I didn't use it much and it was stored in a box. There is no box (?). Operation has been confirmed. Please purchase if you understand that this is a used item.
