🔔Important Notes: ①These headphones are designed for ears length over 7cm / 2.7inches, so they suit adult men better, as most men have ears longer than 7cm/2.7inches. ②Both modes work well out of water. But when swimming or underwater, only MP3 mode can be used, as ALL Bluetooth signals cannot transmit in water. ③please wear a swim cap over the headphones to secure them firmly and prevent loss. ④Magnetic charger not waterproof, keep dry. ⑤Waterproof for fresh/pool/tap water only.(Not seawater)
🏊IPX8 Engineered for Water Warriors: Built for pool laps, open-water swims, and everyday training, these swimming headphones feature an IPX8 waterproof rating and are submersible up to 6 m (20 ft). Since Bluetooth signals cannot travel underwater, simply switch to MP3 Mode for uninterrupted music while swimming. For added stability during flip turns and intense workouts, we recommend wearing a swim cap over the headphones for the most secure fit
👂Ergonomic & Customizable Fit for All Swimmers: Designed specifically for swimming, these in-ear waterproof headphones feature 30° rotatable ear hooks and soft, skin-friendly silicone for exceptional comfort and stability. Three sizes of specialized earbuds (S/M/L) help create a secure waterproof seal for different ear shapes. Choosing the correct ear tip not only improves comfort but also helps keep the headphones firmly in place throughout your workout
🎵Clear Underwater Audio, Tuned for Swimming: Optimized for underwater acoustics, the S36 eliminates distortion and provides clear, consistent sound while you swim. While the IPX8 waterproof seal naturally prioritizes safety and durability over heavy bass, our 12mm drivers deliver balanced audio that cuts through water noise. Perfect for focus-driven training and rhythmic swimming
🎧Built-in MP3 Player & Bluetooth 5.4: Enjoy seamless Bluetooth streaming on land and reliable offline playback in the pool. The built-in MP3 player stores up to 1,500+ songs (supports MP3, FLAC, and WMA), giving you plenty of music for weeks of workouts without bringing your phone. Easily transfer music from your PC or Mac using the included USB data cable, then switch between Bluetooth and MP3 modes with a simple double-click
🔋Battery Built for Long Swim Days: Fully recharge in just 2 hours via the USB magnetic charger, and enjoy up to 10 hours of Bluetooth mode playback or 8 hours of continuous MP3 mode music. The device is designed to save power; please note that the playback order may reset after a full power-off to protect system stability
