Retail price: 4860 yen (Reference: Amazon price) This is a wired headset from ESKA. Used about twice. From my experience, there seem to be no initial defects. You can hear the sound, and the microphone works. A headset that works without any problems. I ended up buying a new headset for around 10,000 yen, so I no longer need this one. I will pack it in its box and ship it in a bag. Photos 1-3: Actual product. Includes a bonus bag, manual, and plug. Photo 2: Reference image (from Amazon) Immediate purchase is welcome! Thank you.
