The AEROPEX, which utilizes bone conduction technology, boasts IP67 waterproof performance and a 6-hour battery life. - Model Name: AEROPEX - Color: COSMIC BLACK - Connection Method: Bluetooth - Waterproof Performance: IP67 - Battery Life: 6 hours - Features: Bone conduction technology - Design Award: GOOD DESIGN AWARD 2019 I used it a few times after purchase, but have since stored it away. All equipment is included, but one of the charging cords does not have a bag. It comes with a pouch, and the earplugs are unused. There is some slight distortion on the right earpiece, but it does not affect usage. Please consider this as a used item. I will disinfect it with alcohol and ship it in the original box with the instruction manual, etc.
