Shox Open Run Pro 2 Bone Conduction Earphones Black

I bought this as a gift for my father, but he found it uncomfortable and hasn't used it at all, so I am selling it. It is the Shox Open Run Pro 2 bone conduction earphone. It is black, and as you can see in the photo, the package includes the main unit and a case. It is great for comfortable use during workouts or in daily life. You can enjoy music while hearing ambient sounds, making it safe to use.
