Stethescope
I purchased this because I am in the process of becoming an EMT. Seems to do well so far and seems heavy duty enough for daily use. The ear pieces are comfortable.

I can hear EVERYTHING!
I love my new stethoscope. I've never purchased a Littmann pbefore but I'm happy I decided to try this brand out. I was a little taken back by the flimsy tube. I have to get used to that. But overall I am satisfied with my purchase.
