【Bone conduction technology 】Bone conduction is the conduction of sound to the inner ear primarily through the bones of skull, allowing the hearer to perceive audio content without blocking the ear canal. The sound is directly transmitted to the auditory nerve through the skull without passing through the eardrum, which reduces the irreversible damage to the eardrum hearing. The bone conduction headphones can help to pay attention to the outside dangerous signals.

【IPX8 Waterproof Swimming Headphones 】It’s tested that when immersed in water of 2 meters deep, the Bluetooth swimming headphones still performance well. The waterproof protection is also great for those who build up a good sweat while doing sports, making them the perfect underwater headphones for Swimming, Running and Cycling, Sauna & Steam Room, as well as all other outdoor/indoor activities.

【16G Wireless MP3 Player 】With 16G memory card, the open ear headphones can store thousands of songs. As Bluetooth transmission will be influenced by water, Bluetooth mode cannot work underwater. You can still enjoy music by MP3 mode when you are swimming or diving underwater.

【Magnetic Quick Charging 】Upgraded magnetic absorption charging, makes data transmission more effective. Magnetic absortion charging, convenient in use, fast in charging, the female end of magnetic absortion charging line can realize dust proof and waterproof, which makes bone conduction swimming possible.

【Bluetooth5.0 】The latest bone conduction headphones Bluetooth 5.0 chip brings stronger and faster connection. The waterproof headphones for swimming can effectively reduce the acoustic synchronization delay, and effectively improve the signal stability, transmission distance and reduce power consumption.
