A fantastic multi-purpose listening device which is perfect for people with difficulty hearing due to a mild conductive hearing loss especially children with glue ear.  The sound bypasses the outer ear, eardrum and small ossicles and is transmitted directly to the outer and inner hair cells of the ears.  It is  a high quality personal amplifier rather than a hearing aid.  It is perfect for wear even during sports and rain as it is sweat and rain resistant due to its IPX7 rated manufacture.  It is not to be worn whilst bathing or swimming.
