Yes, bone conduction should bypass any conductive hearing loss in the outer/middle ear. If you still can't hear that's an inner-ear (or brain) problem, and if that's new you probably want to get to ENT as a point of urgency...
That said, when I tried a set of Aftershokz, most of the higher frequencies arrived at my ear through the air. It's hard to achieve pure bone conduction when you have normal hearing, as bone conduction transducers leak, and they appear to be engineered to take advantage of this (hence the transducer in front of the ear, rather than over the mastoid as is traditional). I have to block my ear canals to listen to barakta's BAHA via a bite-bar, for example.
