ZLOS EP03 In-ear 32GB IPX8 Waterproof Long-lasting Battery Earhook Bone Conduction Bluetooth Swimming Headphone

The ZLOS EP03 In-ear Headphones are a must-have for active users and water sports enthusiasts. With an IPX8 waterproof rating, they're perfect for swimming and diving—note that Bluetooth mode is unavailable underwater, so you can switch to the MP3 song storage mode to enjoy music while swimming. A key highlight of this mode is the headphones' 32GB built-in storage: they already come pre-loaded with over 100 songs for immediate use, and you can further expand your music library by directly importing your favorite tracks via the magnetic charging cable. This means you can enjoy offline playback even without a Bluetooth connection to a device, whether using the pre-stored songs or your personalized collection. In addition to this water-friendly playback option, the headphones feature hypoallergenic silicone for all-day comfort and the Triangular Secure Fit System, which ensures a stable fit during intense activities. Powered by Bluetooth 5.4, they support seamless wireless playback when above water, while their internal-magnetic driver delivers underwater-optimized Hi-Fi sound for immersive audio in and out of the water. A 230mAh battery provides up to 10 hours of playtime, and the combination of a magnetic charging port and physical buttons makes operation easy—even with wet hands.
