3MTM Littmann Cardiology Stethoscope

I love this stethoscope! I researched stethoscopes in great detail until I made a purchase, as this is not a cheap buy and not one I want to replace any time soon. I chose the pediatric bell instead of the master, because I have small children and it is proving itself very useful. The sound coming from this is amazing. I am not a medical professional, but am learning how to use medical instruments for home use. My Midwife has the Littmann Classic II and loved it, when it was new, and I have had the privilege of using it and hearing through it. This Cardiology IV blows it out of the water. The sound and clarity is astounding, I can hear everything. I'm really enjoying learning the sounds of the internal body, as are my children. I'm not a professional, and I haven't tried a bunch of different stethoscopes, but I would totally recommend that anyone at least try this. My only con is the tightness of the ear pieces. I know the insteuctions say to pull them open wide to loosen thrm, but this really hasn't worked, as they are still quite tight. I see other brands of stethoscopes that have a better adjustable piece forwhere the tubing ataches to the ear pieces (not sure what those metal pieces are called). Also, the instructions could be more clear in explaining how only one side of the bell works at a time and to hear each side, you need to rotate the bell piece on the stem.
