I just had my hearing checked found that I could use hearing aids. I have a adscope electronic stethoscope 657 series.

my question is how well do you think it works. I i was surpised by how much it pickup and how much more I could hear. 

Two of the nurses at a hospital I worked had them. One had hearing loss from a brain tumor and one just had diminished hearing for whatever reason. They both loved them. I tried with one of their stethoscopes like yours and it is like turning up the sound on the radio/tv. They really do amplify the sounds. If the price is not an issue it would be great to have.  One of the gals took out her hearing aids to use the stethoscope, the one with the brain tumor post surgery did not. Thats all I know about them. Good luck!
