Help! Can anyone tell me where to get custom earbuds for stethoscopes? I have great hearing, but weird ear canals, according to an audiologist. I can hear sometimes, but then when I move my head the sound totally cuts off, sometimes in the middle of reading a B/P. My audiologist says she can make custom earbuds, but that they would need to permanently attach to the stethoscope. Since I am not sure if this will fix my problem, I don't want to permanently change the stethoscope. Any help as to where I can get custom earbuds that just slip on would be SO appreciated! Thanks.
