Trying to find a good stethoscope

I would like to buy a stethoscope for my nurse's aid clinicals and then also to use for my 2nd degree accelerated BSN (that starts in August). I don't want to buy a nice/fancy one because I know my mom will buy me a super nice one when I graduate and get my first RN job. However, I do still need a decent one that works!!

My only problem is that I have very small ears. Earbud type headphones for MP3 players and stuff don't fit my ears because my ears are too small. So I need ones that have softer type earbuds or something for it to work!

In my nurse's aid class today we used dirt cheap ones with hard earbuds and I couldn't hear anything on them because they didn't fit right. I have used others that were much much nicer that I could hear on (but too expensive for me now).

Anyways - any suggestions would be much appreciated.
