XP is proud to present the first bone conduction headphones designed for metal detecting, BH-01. Made in France by XP, it is waterproof IP68 so you can dive with your DEUS II (only) up to 66ft/20m deep. Using ordinary waterproof headphones underwater, the ear fills with water and hearing is often lessened. 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. Your ears are therefore free. In disturbed or noisy water, you can dive usefully with ear plugs to avoid infection or simply to isolate yourself better from noise. You will thus hear the sound perfectly by bone conduction whilst protecting your ears. BH-01 also allows the hearing impaired to feel the vibrations generated by the targets towards the cochlea, or simply the vibrations depending on the type of alteration of the hearing system. Adjusting the audio frequencies downwards (100 to 300Hz) could further improve perception depending on the disorder.
