Price reduced. This is Shokz OpenFit Air. I bought it new and tried it a few times, but it doesn't fit my ears, so I'm selling it. The box, instruction manual, unused cable, the main unit, and the charging case are all included. The case was kept in a perfectly fitting case I found at a 100-yen shop, so there are no scratches. Since it's only been used for listening, there are no scratches or stains on the main unit, but please understand that it's not new. It's a bone conduction type that goes over the ear, so you can hear outside sounds, and there's little sound leakage. The sound quality is also good, and I really liked those aspects. You can also operate it by tapping the main unit, which is comfortable. Bluetooth connection is also instantaneous, completing before you put it on your ears. Charging is done by plugging a USB-C plug into the case. The main unit charges when placed in the case. It's white, so it's easy to find and less likely to be lost. It's the type that doesn't go in your ear, so it's easy to wipe clean and keep sanitary. As a bonus, I'll also include the 100-yen shop case.
