BH-01 sits in front of the ears on the cheekbone and transmits sound to the inner ear directly through vibrations applied to the bones, without straining the eardrums.
^^ Waterproof: certified IP68 for submersion up to 20m, waterproofing and pressure resistance guaranteed to detect underwater with your XP DEUS II metal detector. ^^ In disturbed or noisy water or simply to isolate yourself better from windy and noisy environments. You will thus hear the sound perfectly by bone conduction whilst protecting your ears.
^^ Multi terrain: Also use these headphones on land with the freedom of being able to hear your surroundings or, conversely, to isolate yourself from noisy surroundings with ear plugs. ^^ The XP BH-01 bone conduction headphones are supplied with a storage bracket, designed to last, with a 2 Year warranty and are also fully made in France.
