Do you have a source for any good bone conduction headphones? I have a damaged eardrum that stops me hearing low frequencies. Recently tried a demonstration at SF's Exploratorium which involved biting a metal bar, and the result was incredible! Most bone conduction headphones I find when searching (eg AfterShokz) appear to rest against the bones around the ear, so I'm not sure if they're as effective.
