SHOKZ OpenComm2 UC Bone Conduction Headset This is a bone conduction earphone from SHOKZ. I used it for about a month. It's a very good product, but it didn't suit my work environment (noisy surroundings), so I'm switching to a headset and selling this. ・There are no noticeable scratches or stains. ・As shown in the photos, all the original accessories, box, setup guide, warranty, etc. are included.
