Chris .....
I am not a doctor but to my knowledge, the Soundbite works on the same principle as a BAHA, just conducts the sound through your teeth, instead of through the abutment implanted in your skull. Both conduct the sound coming in through the processor to your remaining good auditory nerve.
Technically it is not "stereo" because both channels (as it were) are being received on one side.
According to Dr. Adkins (my audiologist) in a normally hearing person, the sounds coming into the left ear are transmitted through the left auditory nerve to the right hemisphere in the brain (then back to the left hemisphere, where speech/language is processed) ..... the right ear sounds go through the right auditory nerve to the left hemisphere. Therefore, if one of those nerves is severed or irreparably damaged, no sounds can go through to the brain. What bone-conduction does is by-pass the bad nerve and is picked up by the remaining good one, along with the normal sounds coming from that side.
All that being said, I have a BAHA (Oticon Medical Ponto Pro) and technically I am not supposed to have directionality from it, but apparently my brain has learned to distinguish the difference in the sounds between the bone-conducted and the natural, normal hearing from my good ear, because I do have a certain level of directionality. I also have a music setting on my Ponto that essentially opens up all of the frequencies for a better "stereo effect." If I plug my good ear I can hear excellent sounds from my BAHA, otherwise I am totally unaware it is working.
Hope some of that makes sense.

P.S. I also have an single earbud that receives both channels for listening to music with my iPod ..... not stereo, of course, but at least I "hear" both channels.
