Cardiology IV vs Cardiology III vs Master Cardiology
I’ll start off by saying that I am careless with Stethoscopes, which is how I ended up writing this review in the first place. Intubation? Lost stethoscope. Central line? Lost stethoscope. Five minutes for lunch? Probably microwaved my stethoscope. The life of an ER resident is crazy, surreal, and amazing. It is also provides the optimal conditions for evaluating stethoscopes. Maybe you’re starting medical/nursing school and this is your first big purchase, or maybe you’re a veteran at the game and this will be the last of your career. Either way, this is a worthy upgrade to the Cardiology III, and maybe even the Master cardiology.First, i’ll start with the similarities. I’ve owned all three and the acoustics are going to be a dramatic step up from a cheaper brand or model. So now that we’re in the ‘top tier’ with these three, the differences at the top are going to be more subtle.As far as acoustics, Cardiology IV and Master Cardiology are comparable. Anecdotally, I find the Cardiology IV is better at isolating background noise. You will easily pick up any grade 2/6 murmur with either of these models (A guess a better question might be, does it matter?). The cardiology III lags just a bit behind. To a novice med or nursing student, the differences will not be appreciable. But for those who have trained on a lower quality product, you will be pleased with the upgrade.Tubing: The Master Cardiology and Cardiology III both have your standard rubber tubing. The cardiology IV is equipped with a noticeably thicker (and stiffer) synthetic. What this translates to practically is a more comfortable position on your neck (It stays put). I much prefer the new tubing, although time will tell with durability.Size/weight: Master cardiology is the heaviest, with a large diaphragm that will make you feel like a giant on your pediatrics rotation. It also feels to be the most solidly built. Next is the Cardiology IV, which on my kitchen scale weighed 7 grams more than my cardiology III. Practically, it feels to be a similar weight and diaphragm is a similar size. However, the build quality is a huge step up from the Cardiology III. This thing feels solid and is a pleasure to hold.Other features: The tunable diaphragm on the Cardiology IV is top notch. It allows the small diaphragm to be utilized strictly for smaller humans, which is perfect for many fields.Warranty: Who cares? You’ll lose all three before you replace one.Colors: I went for standard black on my Cardio III as it was my first stethoscope and i wanted to be professional in my selection. I purchased the Cardiology IV in Hunter Green and could not be happier with that decision. It is elegant and professional, but also different enough that it allows quick identification. I honestly would encourage going against the grain and selecting an actual color. It will bring you joy during those long days and also serves a subtle kick in the butt to the hierarchy and pretentiousness of medicine (At least in my own head).In short, I would highly recommend the Cardiology IV over the others. While the Master Cardiology may have the best acoustics (Debatable), it is clunky and impractical if you have to see kids. It is also noticeably heavier and will likely end up off your neck. There is simply no reason to buy a Cardiology III anymore unless you buy it at steep discount (I’d still probably spend the additional cash on the better model). I coincidentally found my Cardiology III a few days ago and briefly considered returning the Cardio IV, but I just couldn’t bring myself to do it (I don’t know if i’d recommend as an upgrade unless you are ready for a new stethoscope). At least I’ll have a spare :)Left is Cardiology III in black, right is Cardiology IV in Hunter Green, 27 inch. Master Cardiology is probably in a refrigerator somewhere.

$$$$: and totally worth every penny
I’ve used my ancient Sprague-Rappaport stethoscope for more years than I care to admit. Its a very sentimental piece of equipment but is bulky, somewhat heavy and the tubes are deteriorating. I was looking for a more streamlined, lightweight and highly sensitive stethoscope now that my hearing acuity is decreasing with the normal aging process. Disclosure: I did not try various stethoscopes before making this purchase; I based my decision on rave reviews so I cannot compare this one to others on the market.Upon auscultation of heart, lungs and abdomen, I knew that I had chosen wisely. Sounds are clear with limited distortion, muffling of ambient sounds (e.g. in the room or down the hallway) is quite good. The ear pieces are comfortable and the stethoscope feels lighter in weight and less bulky than my old S-R. The tubing is also much smoother than the tubing on my old S-R and thus the new Littmann slides into my lab coat pocket without much resistance.Being somewhat of traditionalist, I was leaning heavily toward purchasing a black stethoscope but then I read other comments about choosing a different color to facilitate quick identification. The green stethoscope that I received is a dark forest green, not a bright apple green – a welcome change from black but not terribly “risky”!If I have any updates after continued use, I’ll return to post those.

Perfect stethoscope- worth the money!
I bought this stethoscope because I needed a good one as an EMT-> paramedic in training. When you’re on calls, there is so much going on, and it can be really really difficult to auscultate breath sounds, take a blood pressure, etc. This makes it really easy. The sound quality is amazing, and it is lightweight and easy to carry. Worth the money!

Great buy!
Paramedic student here. Bought this stethoscope as an investment. I’m not disappointed at all. The deeper bell really helps hear more quality tones. The thicker tube helps reduce some of the road noise. I’m sure I’m only using this thing to 20% of its potential but I’m very happy with it.Only con is that it’s a little heavy, compared to the classic.

Received the wrong color
Order a hunter green stethoscope and received a plum stethoscope. Functionality wise it seemed fine, however not any more impressive than my Litmann Classic III I currently have.
L. Hoffman –
Green is great
My old cardiology III got a crack in the tubing after 10+ years of use and I had no idea how poor the sound quality had become until I tried this new one. Its amazing, I can actually hear S3’s and S4’s for the first time! The green color is really nice, much better than basic black, but still looks very professional. Patients actually complement me on the color frequently.

When we try to register the product, it shows invalid sl no.

Another excellent product by Littmann. I’ve used these for thirty years. The models haven’t changed much over time, and they’re virtually indestructible. I would never replace them if I didn’t keep losing them! (or someone at the hospital borrows it and then tucks it away somewhere I can never find)
