Features

  • Outstanding acoustics: The highest in Littmann mechanical stethoscopes.
  • Tunable diaphragm: Hear high or low frequency sounds by slightly adjusting pressure on the chestpiece.

Description

The 3M™ Littmann® Master Cardiology™ Stethoscope is characterized by the best acoustic response in the Littmann mechanical stethoscope line; with a tunable diaphragm, dual lumen tubing, and a precision, ergonomically designed, stainless steel chestpiece. The 3M™ Littmann® Master Cardiology™ Stethoscope features tunable diaphragm technology—a 3M invention—that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two sided models, there’s no need to turn over and reposition 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.Put the power of improved listening in your pocket with the Littmann Learning App. This powerful app is designed to help users better recognize benign and pathological heart sounds, murmurs, and lung sounds. It reinforces learning by offering self-directed learning modules directly on your phone. You can download the free Littmann Learning App now from the App Store® or Google Play Store®.

    • Fantastic stethoscope
Color: Navy Blue Tube Style: Stainless Steel
Love it! can hear great with it!

    • Seriously, all the hype is true!
Color: Black Tube Style: Stainless Steel
Let me start by saying this is the first review I am writing for any product. I just had to write this one! Firstly, I must commend amazon for their excellent delivery service, my package took just about 11 days to be delivered to Nigeria and all along, I was able to conveniently (and accurately) track it. At almost $200, it's an expensive stethoscope I must admit. At $321 (including shipping), it's the most expensive piece of medical equipment I own. The littmann master cardiology stethoscope is GORGEOUS! It has a polished stainless steel chest piece and an overall attractive design. I initially wanted the burgundy colour but it it wouldn't ship to my location so I had to settle for the black one which is still beautiful. For someone used to low quality stethoscopes, even the feel of the master cardiology is different. It screams quality and class. It's also considerably lightweight (I actually looked at the delivery guy like "are you sure there's master cardiology in here?") When I put it in my ears for the first time, and listened to my own heartbeat (over my clothes!), I couldn't believe my ears... the acoustic performance is just excellent. It has an adapter for pediatric auscultation and a single sided chest piece which allows one to listen to both high and low pitched sounds simply by applying pressure on the chest piece. As a young anaesthetist who'd be dealing with both adult and pediatric patients, I couldn't ask for more. It has got soft sealing ear tips that fit perfectly and cancel out ambient noise. In short, when you're looking for a high performance stethoscope which is worth every penny, look no further than littmann master cardiology. Excellent craftsmanship, littmann! ... show more

    • Excellent Quality!!!
Color: Burgundy Tube Style: Stainless Steel
The best analog stet you can get. I lend it to nurses on the floor and they can’t believe how much better you can hear. Worth every penny for doing assessments!!!

    • Sound quality is top tier!
Color: Plum Tube Style: Stainless Steel
The sound difference between the Master Cardiology stethoscope and the standard is very noticeable. The Master is so much louder! We (nurses) compared the differences and it was agreed across the board that the Master is much easier to hear and distinguish all the sounds. Highly recommend!

    • Noticeable difference from Master Classic II
Color: Black Tube Style: Stainless Steel Black Finish
Compared to my trusty Littmann master classic II which I have had over the past 5 years, the master cardiology is a significant step up in terms of sound quality. I am no cardiologist, just a medical student, but I do find the sound insulation on the master cardiology to be noticeably better. The master classic had good isolation and will pick up just about everything this one does, but the cardiology scope is just another step up and feels like putting on a quality pair of isolation headphones. I have had both stethoscopes with me for the past 2 weeks on wards for comparison, and the cardiology does a better job of shutting out ambient noise. This includes doing a better job of shutting out finger contact sounds on the actual chest piece. On the classic, it would pick up some friction sounds; on the cardiology, that is largely gone. For some of the larger patients with distant heart/lung sounds to begin with, this is a benefit. Secondly, the tuned diaphragm on the cardiology is better. The diaphragm itself has a larger diameter and the rubber casket around creates a better contact with the skin to create a better seal. There are some pinholes on the diaphragm which I suppose are there for air flow engineering reasons. Whatever the purpose, the tuneability is impressive. Just leaving the chest piece on on a supine patient (without pressing down at all), I hear clear low pitch sounds. A little pressure, and the higher pitches come out. Finally, the build quality between the two are on par. The tubing is a little thicker on the cardiology because it is a double lumen design. The chestpiece is a little larger on the cardiology and is a little more friendly to use as a reflex hammer because of a wider bezel. All in all, very satisfied with the product. The cardiology scope is way overkill if you're just going to be using it for vitals, but for hearing murmurs, crackles on a larger patient, it is definitely worth the price difference. ... show more

    • Buy once, never go back!
Color: Black Tube Style: Stainless Steel Brass Finish
I've had several stethoscopes throughout my time as a nurse. I currently work in a busy emergency room and this stethoscope is hands down one of the most critical tools that I own. You can hear everything. Whether it is decreased bowl sounds or heart murmurs. This thing picks it up better than any other stethoscope I've ever used and that's saying quite a bit. My go to for years was the Cardiology 3. Unfortunately I left that one at work and it mysteriously walked off, never to be seen again. So a year later I figured for my birthday I'd get a new one. After months of research and trying out some of my coworkers Master Cardiology stethoscopes I decided I'd get one that would last me the rest of my career. Enter this purchase and I've been nothing but satisfied. Seriously, if you're on the fence on what the best tool is for the job. Just bite the bullet and buy this stethoscope. In the long run it'll save you money because you know you have the best and won't ever have to replace ie unless you seriously misuse it. (How? I don't know! It's a stethoscope, use your imagination. ) Anyway, like I said, this is the best tool for the job. Though if you buy this stethoscope just make sure you get the long tube. It'll save your back in the long run. ... show more

    • Sound quality seems slightly superior to MDF. Tubing is a lint and hair magnet.

THE SOUND Initially it was hard to even tell the difference between this Littmann and my much cheaper MDF. But after some very careful listening, I can say that there is a difference. The littmann sounds a bit louder and “warmer” and “cleaner” than the MDF. But i think you will still be able to hear the same thing using either. Maybe the Littmann will be able to pick up something distant the MDF can’t, but I can’t say, I haven’t tested it enough to know. THE QUALITY (PROS) -The tubing is very flexible and maneuverable. It’s like it’s “soft”. -The earpieces are very comfortable! -the diaphragm looks and feels expensive. It’s definitely beautiful. -the tubing is lightweight, while the diaphragm is heavy. Wearing it all around your neck is very comfortable though, it doesn’t feel too heavy. I have a lightweight MDF stethoscope that I wear for 12 hours, and I wouldn’t mind wearing this Littmann stethoscope for 12 hours. THE QUALITY (CONS) -one earpiece came with a small flaw (see picture). -the tubing is a hair and lint MAGNET. It’s HORRIBLE. It has a tacky texture that doesn’t seem so bad just to the touch but it turned out to be a major problem when I tried wearing it around my neck. I cannot wear the stethoscope around my neck without snagging my hair each time. I am not even exaggerating. My hair basically sticks to any part of the tubing. Every time I go to put it on or take it off my neck, it snags my hair. Every time. Even when I try to tie my hair out of the way, the tubing snags on the bun or the ponytail. This is the reason I’m returning the stethoscope. There is no way I can foreseeably use it comfortably for 12 hours straight at work, without ripping my hair out, even when being careful. Also, it attracts lint and I can only imagine what else will stick to it in a medical setting in the span of 12 hours. This is highly unhygienic! I’m sure Littmann tried their best to make tubing that’s flexible and resistant to cracking, but it seems like this resulted in tubing with a sticky texture. Sadly, I found out this is a known issue being reported on the internet, and it seems Littmann is unable to do anything about it. Some people buy fabric covers for the tubing. Littmann has also made “satin tubing” for other stethoscopes that is less likely to stick to hair, but this stethoscope isn’t sold with satin tubing. If I’m paying $230 for a stethoscope, I expect it to be flawless. I shouldn’t have to buy a cover for the tubing or try and tolerate this flaw. Especially when cheaper stethoscopes don’t have this flaw. In conclusion, I would really love to keep this stethoscope, but I’m returning it solely because of the tubing. ... show more
