Product Overview
The MARLALL Swimming Bone Conduction Headphones are engineered for an immersive audio experience both in and out of water. Featuring IP68 waterproofing, these headphones are suitable for swimming and other water sports. The bone conduction technology delivers sound through your cheekbones, leaving your ears open to ambient sounds, enhancing safety during outdoor activities. With Bluetooth 5.4 and an integrated MP3 player, you can enjoy your music wirelessly or directly from the device's internal storage.
