    • Cardiology IV vs Cardiology III vs Master Cardiology Cardiology IV vs Cardiology III vs Master Cardiology
Style: Standard Finish Tube Color: Hunter Green Tube
Review Image by Dr. Adam B
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. ... show more

    • Excellent stethoscope
Style: Satin Finish Tube Color: Midnight Blue Tube
I bought this for my daughter’s nursing school graduation after talking to other nurses to see what they recommended. Since she probably will use this for a long time, I felt getting one that was a step up from the basic stethoscope would serve her better. My daughter loves it.

    • Works great for EMS
Style: Standard Finish Tube Color: Rose Pink Tube
I can't hear a damn thing most of the time. It feels like everyone mumbles their words and I look like I'm deaf after I asked them to repeat themselves for the third or fourth time. I previously have tried to go cheap with my gear, starting with MDF steth for $25, then moving up to an ADC for around $35. They worked fine if I was in a quiet environment, but often times, EMS is not quiet. I saw a lot of people recommend littman as a great brand. It took me a year to bite the bullet, but I'm glad I did. I even got the cardiology IV instead of the III just because I know I'd probably need it. I bought it refurbished, which was about $15-20 cheaper, but it's brand new. Came with a separate set of ear buds and two rubber membrane rings in case the other rings wear out. The Pink color is very vibrant, which makes it easy for me to spot and easy for others to return it to me. The bell turns smoothly, the entire thing is very light and flexible and feels very sturdy. I can hang it around my neck with no fear of it falling off or dragging to one side. I can hear breath sounds no issue and can actually determine if theyre diminished or not. BP is a breeze, even in a loud environment. It's comfortable in my ears and doesn't squeeze too hard, which is great cause my head is fat af. The bell can be removed with not much trouble, which is great because I like charms on my steth. It's also very durable. I've whacked this thing around like it's a ribbon baton and it holds up effortlessly. This thing is my baby. I love it. Overall, worth the money, worth investing in my career. ... show more

Love this! I bought two other cardiology IV, but the texture of the plastic was tacky and gross, I ended up returning both of them due to the sticky nature of the product. This one’s smooth and I can hear everything well. I’m very satisfied with this product, other than the fact that there aren’t as many colors or options. ... show more

Super thick tubing feels great in the hand. I’m just an EMT, and the cardiology iv is more than I need probably, but it sounds incredible. I’ve never had an issue using it.
