1. 3M Littmann Cardiology IV 

Whenever there is a list of the highest-rated stethoscopes that are for cardiologists, the 3M Littmann Cardiology IV will always be found in that list. It is the best double-sided cardiology-grade stethoscope available on the market.

Stainless steel chest piece with a dual-sided design makes it more versatile than the single-sided design. The tubing on these dual lumen tubing is the reason for its fantastic acoustic. That shouldn’t surprise anyone who has ever used the Littmann stethoscope.

Chest Piece Material  Stainless Steel
Tubing Dual-Lumen
Grade  Cardiology
Adult side  1.7 inches / 4.3 cm
Pediatric side 1.3 inches / 3.4cm

Versatile Design

A doctor has to check many patients in a day ranging from old to children. In that case, versatility is a game-changer feature. 

The chest piece design of the Littmann Cardiology IV is the best feature that makes it more demanding than other Cardiology stethoscopes. Unlike many cardiology stethoscopes with a single-sided design, Cardiology IV offers dual-headers with adult size on the one side and the pediatric size on the other. 

Superior Tubing 

Cardiology stethoscopes are designed to have more sensitive acoustic so that listening to the faintest heart sounds can be possible. Therefore, capturing the sound precisely is only the first step; delivering it to the ear without loss is the second. This can be achieved by using the premium tubing style called the dual lumen.

In dual-lumen, a channel in the tube separates the two pathways, each leading to the left and right ears. This increases the acoustic performance by also eliminating the rubbing sound, which can be very annoying.

Convertible Pediatric Side

Aside from offering the adult and pediatric sides, Cardiology IV also allows you to have more choice, thanks to its convertible pediatric side. You can remove the diaphragm of the pediatric side and add the non-chill rim, and it will be converted to an open bell design which is also good for cleaning. 


In our opinion, this model of Littman stethoscope offers versatility thanks to its dual-sided chest piece, and the dual lumen tubing makes it superior in acoustic to others. If you check patients of different ages, this can be a good investment.


  • Stainless Chest Piece
  • Dual lumen tubing
  • Convertible pediatric side
  • Dual-sided design
  • Cardiology grade


  • A little expensive

2. 3M Littmann Stethoscope, Master Cardiology

Master Cardiology is also a Cardiology stethoscope and is considered the best non-electronic cardiology stethoscope manufactured by the 3M Littmann. 

One of the unique features of this stethoscope is that it has a single-headed design which makes the acoustic a little better and a good substitute for cardiology IV if you prefer the single head design over the dual-headed one.

Aside from that, it also has a dual lumen for better sound transmission between the chest piece and headset.

Chest Piece design  Single-sided
Tubing length  22 and 27 inches
Tubing construction Dual lumen
Diaphragm Tunable
Warranty  7 years

Design For Better Acoustic

The acoustic of the stethoscope can affect its performance level, and a single head design offers slightly better acoustics, but the difference is not that much. The reason for that is that there is one opening for sound to enter in a single-sided chest piece, so there is no other way for sound to leak; this leads to better sound detection. 

Comfortable Slim Chest Piece

Another characteristic of this stethoscope is that it has a slim chest piece that is easy to slide under the bandages and pressure cuffs if you want to use it for checking blood pressure. Also, since there is nothing on the other side, manufacture it to be easy to grip. And what Littmann has done, the chest piece is also easy to grip when using, which is not as comfortable in the double-headed design.

Tunable Diaphragm

All of the stethoscopes of the Littmann are equipped with tunable diaphragm technology, which makes diagnosis more easy and reliable. 

With a tunable diaphragm, you can listen to the different frequency levels with the same diaphragm, depending on how much pressure you apply. Lightly pressing will allow you to listen to the low frequency, and firm pressure will allow high-frequency sound. This handy little trick can save time for the doctor to listen to information without moving the stethoscope much, and the diagnosis will be more accurate, so does the judgment.


If you prefer the single-sided chest piece design in a stethoscope, then this one might be according to your liking. It is the best non-electric cardiology stethoscope that can accurately detect detailed heart sounds and offers a 7-year warranty.


  • Superior acoustic 
  • Single chest piece design
  • It offers two tubing lengths to choose from
  • Special-Procedures Adaptor for infant patient


  • The single-sided design has less versatility

3. 3M Littmann CORE Digital Stethoscope

3M Littmann Core Digital stethoscope is the electronic stethoscope manufactured by Littmann. Many non-electronic stethoscopes have higher acoustic performance, but the analogue stethoscopes are limited, which is not a problem for an electronic one. This model is also the most advanced stethoscope of the Littmann.

It has innovative features like active noise cancellation and 40X amplification, which can not be possible with the traditional analogue design. With Dual headed stainless piece and tunable diaphragm, they are a complete set of quality and performance. You can also record the sound and can play it letter thanks to the EKO app.

Type  Analog and digital
Amplification  40 times

Opens The Doors Of Opportunity

This model is the ideal stethoscope for medical professionals with hearing loss because the frequency amplification opens doors of opportunity for them. 

A Littmann core digital stethoscope can apply the frequency to 40 times, making it possible to listen to the sound that even a high-quality stethoscope can not capture. You can easily switch between the analogue and digital modes by dogling the switch of the module.

Eko Mobile App

The advantage of modern technology is its ability to connect it to the mobile and customize it later. EKO is a mobile app available for Android and IOS and can be downloaded free from the respective app store. 

This app allows you to record up to 2-minute recordings, which you can save by creating the file for the respective patient. If you want to, you can also listen to the headphone or earbuds without any issue for maximum comfort.

Active Noise Cancelation 

Noise cancellation is the characteristic that was only associated with the headphones but not any more. This model of Littmann also offers the noise cancellation feature that is innovative and makes it easy to differentiate the noise from the desired sound. 

It can be very handy in hospital environments which is noisy to cause interference with the diagnosis. You can turn on and off the noise cancellation from the mobile app as well as the amplification.


Noise cancellation and amplification makes it versatile for any type of situation. You can also consider that if you have hearing loss. This can be a stethoscope for those who want the highest performance.


  • Active noise cancellation
  • 40-time amplification
  • EKO mobile app
  • A simple switch to change modes
  • Comfortable design


  • For many people, it is out of their budget
  • Amplification sometimes captures little background sound.

4. MDF ProCardial Cardiology Stethoscope

MDF is another top-notch brand of the stethoscope that makes quality stethoscopes which is also considered the competitors of the Littmann’s. 

One of these stethoscopes designed by the MDF instrument is the ProCardial Cardiology stethoscope, which does everything you expect from a cardiology stethoscope and still costs half of the price compared to other quality stethoscopes of the same performance.

It also offers the chest piece attachment of adult, pediatric and infant attachment. This model comes in two versions one is stainless steel, and the other is titanium, not just that the warranty on these is also lifetime, so it will last very long.

Chest Piece material  Stainless steel / Titanium
Safety lock Available
Earbuds sizes Large, regular and small
Headset Ergono Max
Warranty  Lifetime

Safety Lock

The safety lock is the standard of the MDF stethoscope, and all MDF models have this innovative safety lock. This feature is not related to the performance but rather the safety of the user itself. It has a cylinder-like attachment at the end of the headset so that in case the earbuds come off, it will stop the headset from causing any injury, which I have not seen in any other stethoscope.

Premium Material

The material from which something is made can determine its quality or give the perspective of the product’s durability and how long it will last. For example, if something is made from plastic, it will last less than aluminium.

MDF Cardialpro comes in two versions. One is made from stainless steel, which is the standard material for chest pieces to have excellent performance. Either version comes with titanium which is a premium material and lighter than stainless steel. The titanium version also offers more tubing patterns and chest piece finish options.

It also comes with three different attachments to the chest piece ranging from the adult, pediatric and infant.


In a stethoscope, comfort is usually associated with the quality of the earbuds, and MDF offers top quality and soft earbuds. It also gives spare small, large, and regular size earbuds, which are very handy. 

Like when buying clothes and shoes, finding the right size can be difficult. What works for one person may not work for another, so the option to experiment with all three sizes and selecting the best one is very relieving.


In our opinion, this stethoscope can be ideal for those who want their stethoscope to have a unique look because it has a wide range of finished and tubing pattern options. The like time warranty will also offer ease to the user.


  • Premium material chest piece
  • Unique tubing colours and finishes 
  • Three different sizes of ear tips

Among the top stethoscopes for cardiologists available on the market, ADC – 600ST is another best cardiology grade stethoscope made for listening to heart sound reliability. 

It has all the features that other high build quality stethoscopes have dual lumen tubing, chest pieces made of stainless steel and the Ansoft ear tips give you the best stethoscope experience. ADC 600 also have the AFD, which will also you to listen to the high and low frequency with ease. 

Tubing Assembly Bi-lumen
Weight  203 g /7.15 oz 
Chestpiece Type Single-side, ADF technology

Length  27 inches / 68.5 cm

Latex And Phthalate-Free

ADC 600 stethoscope has the capabilities of the cardiology grade stethoscope. Aside from that, it also has ensured the safety of the user and patient. The tubing of this stethoscope is latex-free, which can be a relief for many people because if you have a latex allergy, tubing made from latex can be problematic for you. But you do not need to worry about that when using the ADC 600 stethoscope.

Another thing that shows the companies care about the environment is that they don’t use Phthalate, a family of the chemical used to soften the PVC. The reason for taking this step is that this substance is known for causing damage to humans and the environment, mainly causing damage to the kidney, reproductive system and many other serious health issues.

Adsoft Sanp On Earbuds

The comfortability earbuds are very important if you use the stethoscope for long sessions because if they are not comfortable, it will cause pain and irritation. The earbuds on this stethoscope are Adsoft which is very comfortable and used by many other stethoscopes. 

About the design, they are the snap-on which is a very firm one. You attached it with the headset and will not come off on its own since it required quite the force to do that.

Optimal Length

The length of these stethoscopes is 27 inches which are the most commonly preferred by medical professionals. Everyone has a different preference when it comes to the length of the tubing. If it is too short, you need to get close to the patient, which can be a little problematic, especially during this pandemic. 

To long mean, they will take more space when storing, and the long tubing means more chances to sound loss. 27 length is the optimal length for a stethoscope.


This stethoscope is a good option for people looking for a stethoscope that prefers a single-sided stethoscope and relive of the lifetime warranty. It also offers bi-lumen tubing and diaphragm with AFD technology.


  • Covered by a lifetime warranty
  • Two spare earbuds included
  • AFD technology for low and high frequencies
  • Latex And Phthalate-Free tubing


  • Some peoples find it a little heavy

6. 3M Littmann Classic III Monitoring Stethoscope

If you are a nurse and require a lot of monitoring jobs either in the cardiology ward or another and don’t want to spend a lot of money on an expensive cardiology stethoscope, then Classic III monitoring I made for this purpose.

The dual-headed design will be useful in checking the condition of patients of different ages, from the adult to the pediatric. The pediatric side is also convertible to open bell by removing the diaphragm and adding a non-chill rim for patient protection.

Pediatric side 1.3 inches / 3.4cm

Vibrant Colours

The colour and finish variety is something that most of the stethoscopes lack, and it makes sense since it offers no functional and performance advantage. But the freedom to choose some colour is very important because people want to personalize their stethoscope. 

Luckily the Classic III offers a wide range of tubing and finish. You can get the tubing in Ceil Blue, Plum, Pearl Pink, Gray, Black, Burgundy, Navy Blue, Raspberry, Caribbean Blue, Chocolate, Lavender, Turquoise and Lemon-Lime.

Mirror, Smoke, Champagne, Black matte, Rainbow and Machined Stainless Steel finish in the chest piece.

Rotatable ChestPiece

The chest piece of this stethoscope is rotatable, which is very useful and save some time since time is of the utmost essence during a medical emergency. 

For example, you are checking the adult patient, and you want to use the open bell design, you just need to rotate the chest piece, which will not strain the tubing and, as a result, the headset and ears. Because in classic III, it is the stem that rotates at the end of the tubing.

Tubing Feel

The tubing feel of the Littmann Classic III is very comfortable on the skin. How a tubing feels can directly relate to your comfort. Because most of the time, the medical professionals that use the stethoscope usually wear them on the neck. If the tubing is not smooth, it case discomfort on the neck and if it is sticky, it will pull the hair but not the with 3m Littmann Classic III.


If you are a nurse in the cardiology ward, it is a very economical option without compromising quality. This one is designed for monitoring the patient condition on long shifts. If you have a little more flexible budget than cardiology IV is its improved cardiology grade version.

How To Select The Best Stethoscopes For Cardiologists?


When selecting a new stethoscope, then you first need to determine the kind of acoustic performance you want from the stethoscope. This decision depends upon the point for what you want to use it for.

For example, if you want to buy a stethoscope for blood pressure, any decent stethoscope will do the job. But if you are a nurse and want one for a long shift and monitoring them, some stethoscope with slightly better acoustic will be required, and dual-headed is a wise choice in this case.

And in our case, if you are a cardiologist and check patients with heart issues or work in a critical environment, then a cardiology grade is the ideal choice.

Acoustic Performance

Acoustic performance is essential for determining to what extent it can detect the sound. For example, Littmann has the acoustic performance grade ranges from 1 to 10 for its stethoscope.

A stethoscope with six-level of acoustic performance is for limited general use like taking blood pressure. 7 to 8 acoustic performance is for the classic series, which is ideal for long shifts thanks to its lightweight and monitoring purposes like nurses. 

Then after 9 to 10 comes the best stethoscope, which is designed for cardiology grade uses and above stands the electronic one, the most advanced stethoscope on the market with some fantastic features like noise cancellation and audio storage.


When selecting the tubing, always select the latex-free one because it will not cause discomfort to the patient with sensitive skin. 

In tubing, there are two types of tubing style dual lumen and single. Dual lumen is a superior version of the single lumen where there are two-channel for sound rather than one. This means each ear has its sound channel, which improves the acoustic performance and makes the tubing thicker.


Weight and performance are two factors that are affected by the material used for constriction. Chest pieces made from aluminium have less acoustic than stainless steel, but aluminium one is more lightweight. Stainless steel is the golden standard for the quality stethoscope, so it is ideal to choose stainless steel over aluminium if you prefer better performance.


What Stethoscopes Do Cardiologists Use?

Cardiologists deal with a patient with a critical issue and need to listen to the condition of the heart reliability. That’s why they use stethoscopes that are cardiology grade like Littmann cardiology IV, which can detect the faintest to faintest sound reliability. Cardiology grade stethoscopes are designed for critical environments like ICU and emergency room.

Summing Up

This article aims to present the best cardiology stethoscopes that are easily available on the market, so you don’t have to spend your time researching them.

Choosing the product that will meet your need can be the confusing dilemma we all face when buying something. 

Even if you still find confusing the best out of these eight stethoscopes, we will recommend you to consider the Cardiology IV, thanks to its dual-headed design being more versatile. On top of that, the latex-free dual lumen tubing allows it to be comfortable and give superior performance.
