Lightly Used: Shokz OpenRun MINI Open-Ear Bluetooth Bone Conduction Sport Headphones S803 Black, Behind the Neck Headset with built-in Microphone. Model S803-MN-BK-US. Please note, these are open box ones that may be lightly used (customer returns, so it's hard to say for sure)! I tested them to confirm functionality and cleaned / sterilized them as well. They will not appear to have ever been used to you! Authentic Shokz headset from USA Stock (originally came from Target stores). Buy with confidence. I have excellent ratings and will ship quickly and securely. Please ask if you have any questions. Thanks!
