Bluetooth headset from the well-known company Nothing. Its name is Nothing Ear Open. The idea is that you can listen without having an earbud in your ear. It hangs like in the last picture so your ear doesn't get tired over time and it's completely safe. Lightly used and the headset is fully functional. The outer plastic has scratches because it's made of acrylic material, which is normal with use. It comes with all its accessories: cable, manual, and box. You can download the headset's app on your phone. Its new price is around 400-450. I'm selling it for 250. Please do not haggle 🌹
