Bests & Worsts Reviews from Amazon

So at the risk of sounding really ridiculous -- I also have the Littmann lightweight and the Cardiology IV. In comparison: The Classic III is much lighter weight than the Cardiology IV but does not sound even close to as clear (which makes sense). It is still good sound quality and I will use it for my lung sounds and GI sounds but not for CT-ICU patients. In comparison to the Littmann lightweight, it is obviously much heavier of a stethoscope to carry around. The sound is much more high quality than the lightweight so I like to use this one on day shift when I need more noise cancellation. I also think the sound quality of the classic ii is very similar to the iii. The tubing is sturdier on the iii and noticeably heavier.
