Stormopen SportFit II — On-Ear IPX5 Wireless Running Headphones

The Stormopen SportFit II On-Ear IPX5 Wireless Running Headphones elevate sweat protection to a certified IPX5 level, qualifying for sustained low-pressure water jet exposure as defined by IEC 60529, making these headphones suitable for running in rain as well as intensive sweat-generating workouts. The IPX5 certification is achieved through a multi-layer sealing architecture: the main driver housing uses overmolded TPU gaskets at all seam lines, the 3.5 mm auxiliary input port is sealed with a plug cap rated for 200 removal cycles, and the USB-C charging port uses a magnetic seal flap tested to 500 open-close cycles. The earpads are constructed from a proprietary moisture-wicking textile blend of 70 percent polyester and 30 percent polyurethane foam, drawing perspiration away from the skin contact surface and allowing it to evaporate through the outer fabric layer. This moisture management keeps the pad surface dry during workouts lasting up to 90 minutes at high exertion levels. The 40 mm drivers are angled at 15 degrees toward the ear canal, optimizing the acoustic axis for on-ear driver placement and improving high-frequency clarity. The 750 mAh battery delivers 24 hours of wireless playback. An integrated voice assistant button supports both Google Assistant and Siri. Net weight is 198 g.
