    The 3M™ Littmann® Cardiology III™ Stethoscope is designed for clinicians who require outstanding acoustic performance combined with exceptional versatility. Its innovative design provides a tunable diaphragm on each side of the chestpiece.

    The 3M™ Littmann® Cardiology III™ Stethoscope, one of the most recognized stethoscopes in the profession, features tunable diaphragms on both sides to deliver outstanding acoustic performance, diagnostic versatility, and convenience for treating adult and pediatric patients. The pediatric side of the chestpiece converts to a traditional open bell by removing the tunable diaphragm and replacing it with the included non-chill bell sleeve.

    Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.

    Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.

    Resilient next-generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human health and the environment, the next-generation tubing does not contain phthalate plasticizers.

    The Cardiology III stethoscope isn’t just for cardiologists. It is used by specialist and general practice physicians, critical care nurses, EMTs, medical students, and other healthcare professionals to identify, listen to, and study cardiac, lung, and other body sounds in adult and pediatric patients. The Cardiology III stethoscope is made in the USA for consistent quality. It comes complete with large and small soft-sealing eartips, large firm eartips, non-chill bell sleeve, and instructions.

    Suggested Applications

    • Used as a diagnostic tool as part of the physical assessment of cardiac, adult and pediatric patients. Ideally suited for: cardiologists, critical care nurses, EMT, ER doctor, nurse practitioner, pediatric specialist, physician assistant, registered nurse, respiratory specialists, medical students and nursing students

    3M™ Littmann® Cardiology III™ Stethoscope is rated 4.8 out of 5 by 51.
    Rated 5 out of 5 by from Great product I bought this a month ago and I love it but I wish that there was a way where you can adjust the volume based on how low or high you want to hear body sounds

    Rated 5 out of 5 by from Trusty stethoscope I bought this during nursing school 12 years ago. I use it every day, then cram it in my backpack. It retains it's shape very well, and has perfectly clear sound. It still looks brand new! I wipe it with alcohol between patients and caviwipes at the beginning of every shift. My peers often ask to use my stethoscope because it's better than theirs. I have a maroon color tubing and it's color hasn't faded at all. I haven't needed to replace the diaphragm or the ear buds. I love this thing! Highly recommend it! (I work in a pediatric hospital, and have used my stethoscope on every unit- critical care, cardiac, hem/onc, ED, med/surf, OR, etc. I've also worked adult critical care)

    Rated 1 out of 5 by from Poor quality diaphragm I purchased the Cardiology III at the beginning of Paramedic School in August. I also started working for the local Emergency Ambulance Service. By October the large diaphragm, had a large indention/ significant scratch. I went online to Littmann and filled out a form for a warranty on the Chestpiece. Never Heard back from them. Now in January the large diaphragm cover fell off. Very poop customer service

    Rated 4 out of 5 by from excellent function - issue with light colour tubin Agree 100% with other reviews - excellent function. No complaints. Just a heads up for choosing colours...I selected the turquoise/smoke combo (loved it) but the light colour tube has become stained/discoloured to the point that a brand new item now looks dirty and worn. Have followed all care advice and am VERY careful with it, not sure what the marks are but seem to be manufacturing rather than anything I've done. Happy that it is replaced under warranty but sad I lose my pretty blue. This is worth noting if you are fussy about colours - if I'd known that I would need to replace with darker tubing I would have got stainless steel ear/chest piece colour!

    Rated 5 out of 5 by from Respiratory therapist I bought the Cardiology lll as a student for my first clinical rotation and I have loved it ever since. The pediatric side is great not only for little guys but for listening to the upper airway and perfect for the hard to get to places (around lines and leads.) I can not say enought about how wonderful the cardiology lll is !! WORTH EVERY PENNY - RT's out there, this is the pick. You too will love it.

    Rated 5 out of 5 by from Love my cardiology scope! I bought this as a graduation gift to myself after nursing school 2 years ago, and I love it. I had the Classic II during school, and this is such an improvement. I'll get in report that a patient has very diminished breath sounds, but I can always hear breath sounds very clearly with this stethoscope. The only two things that bother me about this scope is that some of the ceil blue color has worn off and is showing black in some places, and that it feels very heavy on my neck. But these factors don't affect the functionality, so overall - an amazing stethoscope :)
