AfterShokz AfterShokz Bone Conduction Headphones AS800 Cosmic Black I used these for my bicycle commute, but I'm selling them now that I commute by car. Used only from summer to autumn. I didn't use them every day, but there are some scratches and dirt. Please understand that these are used items. Please refer to the photos for the box and accessories. I haven't used anything other than the main unit and the cable, I just looked at them.
