Benefits
Open-ear bone conduction keeps ears free and reduces ear canal pressure, which many swimmers find more comfortable than in-ear buds. The onboard 32 GB memory stores thousands of tracks so you can leave your phone on the pool deck and still enjoy playlists. IP68 waterproof protection and a nano-sealed coating help guard internal components after repeated exposure to water. Bluetooth 5.4 improves pairing stability when you are above water and Bluetooth 5.4 also lowers dropouts near crowded pool areas. 🎧
Practical tips
Use MP3 mode for all underwater sessions and confirm file formats are supported, such as MP3 WAV WMA or FLAC. Double-click the multifunction button to toggle modes and dry the microphone after swims to reduce call quality issues. Keep the magnetic charging cable handy for quick data transfers and for recharging between workouts. Be aware that Bluetooth will not transmit while submerged so plan playlists ahead of time.
