Made with high-strength waterproof and dust-proof silicone materials, the charging case including the port are safe from water, sweat, or dust damaging the box.
You can place the earphones in the case to get charged just after your workout and you are sure that everything is in fully working condition. The magnetic sensor also makes the box easy to open and close to protect your earphones without taking your time and effort when you are in a rush on a busy day at work.
