Littmann’s cardiology IV is one of the most efficient stethoscopes out there when it comes to listening to the faintest to faintest sound in the human body. Listening to the lungs is very easy with these as it is the best stethoscope for lung sounds.

The chest piece design on these is dual-headed with a tunable diaphragm allowing you to listen to different frequency ranges. Due to being the cardiology grade, they are also ideal for cardiologists. They are considered the best cardiology-grade stethoscope that you can find on the market.

Cardiology Grade

If you are looking for a reliable stethoscope that can listen to the lung sound, then cardiology IV is capable of more. The cardiology IV is a cardiology grade stethoscope and is the benchmark for stethoscopes on the market in terms of performance and build quality.

The dual-headed design also makes it more flexible when it comes to different patients. Since it also has a pediatric side, checking the pediatric patient is also convenient with these.

Dual Lumen Tubing 

Tubing is the primary connection between both headset of the stethoscope and the chest piece because it delivers the sound. So it makes more sense than if the tubing is of high quality and performance, so will there be better acoustic.

Dual lumen tubing has two different channels that lead to each ear. This removes the rubbing sound and also reduces the sound loss to a great extent.

Improved design

Cardiology IV is the improved version of the already top-notch stethoscope Classic III, allowing it to have cardiology-level performance. The chest piece is 40 percent larger, and the bell has 60 percent more depth. 

The tubing is also upgraded in this version to the dual lumen. All these improvements enable it to listen to more sensitive sounds than before, making the diagnosis more reliable.


The high-quality chest piece and the dual lumen combination make it the overall best stethoscopes for lung sounds. Based on its feature, it is better suited for a critical environment such as the emergency room and intensive care unit.


  • Cardiology grade performance
  • Dual-sided designs are more versatile
  • Tunable diaphragm  
  • It comes in two different tubing lengths


  • Little expensive 

2. 3M Littmann Classic III Monitoring Stethoscope

Monitoring the patient’s condition is another essential task of the medical staff because even after the patient’s treatment, proper care is essential for its complete recovery. And mostly, this is the responsibility of the nurses, and they have to spend long shifts on that, so a lightweight stethoscope is a must-have in a stethoscope. The Littmann Classic III monitoring stethoscope has all these features.

All the classic series have the lightweight in a common trait, but what makes this one special is the dual sides with the stainless chest piece with better acoustic and different color choices and is one of the top stethoscopes for lung sounds and blood pressure.

Series Classic
Weight 150 grams
Tubing length 27 inches / 71 cm
Pediatric side 1.4 inches / 3.4 cm
Adult side1.7 inches / 4.3cm

Build For Long Shift 

Littmann’s classic series stethoscope is Littmann’s most lightweight stethoscope, and the classic III weighs 150 grams, which is very light compared to many other stethoscopes. If you are a nurse or have some relatives that are, then you may be aware of how long shifts they have to do. The weight of the stethoscope might look too much, but the long session adds up, and if you suffer a neck injury, then you should choose something lightweight. 

Premium Material

The reliability of the Littmann stethoscopes is well known among medical professionals since it is one of the biggest manufacturers in the market. The chest piece of the classic is made from stainless steel, which offers better acoustic sensitivity and less sound loss. Stainless steel is the standard material for chest pieces; that’s why all the premium ones have stainless steel.  

Convertible Chestpiece

The versatility is convenient when it comes to the stethoscope that is desired to use for patients of different ages. The Littmann Classic III has nailed that by offering the dual-sided chest piece for adults and the pediatric sides for more freedom. Both side diaphragm is also tunable, and the pediatric side can also be converted into an open bell design by removing the diaphragm and attaching the non-chill rim.


In our opinion, it is a good option for the nurses that are often required to check the condition of the patients on a long shift. It can also be a good choice for the students that want a quality stethoscope from the start.


  • Lightweight design for a long shift
  • Dual sides, Pediatric, and adult side
  • The pediatric side is convertible to open-bell 
  • The next-generation tubing 


  • Tubing on these are only single lumen

3. MDF Rosegold MD One Stainless Steel 

The most desired expectation when buying the stethoscope is the performance, but one thing that is often neglected is the aesthetic. That is because many manufacturers do not offer many color and pattern options when making a stethoscope, but MDF is not one of them; they offer a wide option of tubing and chest piece finishes. The chest piece of this stethoscope also comes in two different materials. Overall, it’s the best stethoscope for lung sounds.

Safety lock Available 
Colour 11 variation 
Chestpiece optionStainless steel and Titanium 
Headset Dual-leaf spring construction
Engraving Available

Vibrant Colors

MDF stethoscopes are known for their quality and the unique color options, and the finish they offer. You can get the tubing and the chest piece in many variations. The most popular is the Rose gold finish.

Another feature that differentiates them is the material variation they have. In some models like this one, they also make their chest pieces from Titanium and stainless. 

The titanium version costs a little more than the stainless steel one because Titanium is a little more expensive and premium material. The titanium version is also more lightweight because it is lighter than the other material and more durable.

Safety Lock 

Ears are the most sensitive parts of the body, and their safety is essential. In a low-quality stethoscope, when the earbuds come off accidentally, the narrow tubing can injure the ear canal. 

However, MDF has fashioned an innovative solution for that: the safety lock. The earbuds on the MDF MD one stethoscope are of good quality and do not come off easily, and the safety lock will save you from any unfortunate incident. 


We have all lost our important stuff either due to someone stealing it or because we have forgotten it somewhere while we were busy. And even if we find it in someone’s possession, there is no way to make sure whether it is ours or not. 

You can engrave your MDF stethoscope if you buy it from the MDF for some additional cost; you can engrave your name on them. Or you can also engrave your name in the chest piece from your jewellery store. 

This reduces the chances of it getting lost. For example, you forget if someone finds it, they can know your name from the engraving and can inform you.


A unique color range and the performance of this stethoscope make it a good choice for those in the medical profession seeking quality and a unique appearance. And the safety lock makes it a more reliable option.


  • Exceptional build quality 
  • 11 colour variation
  • Lightweight design
  • Safety lock 


  • Some finds eartips little less comfortable 

4.3M Littmann Stethoscope, Master Classic II

Littmann has created many stethoscopes for every need, from basic to the most advanced on the market. 3M Littmann Master Classic II is a stethoscope made for the individual that prefers the single head design and excellent acoustic performance. As the diaphragm on these headphones is tunable, it allows you to listen to low and high-frequency sounds with ease.

The chest piece material is also durable, and the tubing on these is thicker than the standard stethoscope. With these, you will be able to listen to the lung sound with ease, along with blood pressure and many other low-frequency sounds in the body without any struggle.

Brand Littmann
Chest piece design Single-sided 
Tubing Length 27 inches
Chest piece size1.75” / 4.4cm
Material High-density zinc alloy

Single-Sided Design

Everyone has a different preference, and if you prefer the single head design with better grip and sound quality, then this model of Littmann is for you. The single side design also makes sure there is no sound leakage since there is only one opening for sound to enter.

This design also enables the chest piece to be slimmer than dual-headed and make grip since there is nothing on the other side. The slim feature comes in handy when checking the blood pressure because it is easy to slide it under the pressure cuffs.

Latex-Free Tubing

Master classic II tubing is latex-free because it is not made from natural rubber; instead is made from PVC. Natural rubber can cause an allergy if you are allergic to latex. So it is beneficial for people with sensitive skin or the ones who treat a patient that has. 

Another substance that Littmann avoids in the manufacturing of tubing is phthalate plasticizers. This chemical is used to soften the PVC but is harmful to the environment and the people, so Littmann does not include it since making the phthalate plasticizers free tubing.

Tunable Diaphragm

As with all other models of Littmann stethoscopes, this stethoscope has a tunable diaphragm as well. A tunable diaphragm is mainly found in the quality stethoscope. You can able to listen to the low and high-frequency sounds without rotating the chest piece. All you need to do is to change the amount of pressure. 

To listen to the low-frequency lung sound, lightly press the chest piece. This allows the diaphragm to vibrate easily and detect low-frequency sound. For high frequency, firmly press the chest piece. This restricts the diaphragm movement, and it will capture the high-frequency sound.


In our opinion, the single head design and tunable diaphragm enable it to take a reliable reading. The EMTs and the nurses will find it reliable. The veterinarian can also consider it as an option.


  • Slim and durable design
  • Due to single-sided design offer excellent grip
  • 27 inches long tubing
  • Tunable diaphragm 


  • The single-sided design makes it less versatile

So despite being a single-sided design, it can give an acoustic performance of the diaphragm and the open bell in response to change in pressure, so you are setting the same performance as dual-headed. The single head design also gives a better sound performance.

Adsoft Plus Eartips

When it comes to the comfort of the stethoscope, it widely depends upon the quality and the comfort of the ear tips. The ear tips on this Adscope 615 Platinum are of Adsoft design which is made from a soft and comfortable material. It also creates a good seal in the ear, reducing the ambient noise from interfering. They also come with an extra pair of ear tips as a backup.

When you purchase this ADC stethoscope, you can rest assured that a lifetime warranty covers the product.


The lifetime warranty and similar performance at a lower price than a competitor can make this an attractive investment if you’re looking for a single-headed design with long tubing.

6. 3M Littmann CORE Digital Stethoscope

The most advanced stethoscope of the Littmann is their Littmann core digital stethoscope. By using such a stethoscope, things are possible that could not be done in an analog one. This stethoscope has amazing features like noise cancellation, which can be handy in noisy areas, and the 40 X amplification of the sound in the digital mode.  

Along with all these features, this stethoscope also supports the EKO mobile app that can record and save the data of your diagnosis. Also, both sides have a tunable diaphragm, with all the standard features for Littman stethoscopes. 

Stethoscope Digital 
Sound amplification 40 X
Active Noise CancellationAvailable 
Mobile app EKO
Models Analog & digital

Noise Cancelation 

In the emergency room or ICU, there are times when the environment becomes very noisy. In an analog stethoscope, the common solution is to focus or make sure you are in a less noisy area which is very troublesome. In a 3m Littmann core stethoscope, you just need to turn on the noise cancellation, and all the background sound will disappear. This will result in more accurate reading, and judgment will be more reliable.


Sometimes the noise is not the only reason it is hard to judge the sound. Sometimes the sound is too faint to begin with, even in the silent room. You will not face this issue because of the 40 times sound amplification in digital mode. The ability to amplify this much sound can open new doors for individuals suffering from hearing loss. If you just want to use the stethoscope with only analog mode, only press the button on the top of the chest piece.

Mobile App

One of the many advantages of digital data is its ability to store and share. The same can be done with Littmann core by installing the mobile app EKO, which is available for Android and ISO devices. You can turn on and off your noise cancellation and activate amplification through this, not just that you can record the audio from 15 seconds to 2 min depending upon the setting. This feature will come in handy when you need a second opinion from your co-worker or the doctor.


Amplification ability and noise cancellation feature open up many opportunities for the individual with a hearing problem. This stethoscope is ideal for any situation due to its ability to detect even the weakest sound.

3 In 1 Chestpiece 

Versatility in a stethoscope is a feature that can be a game-changer. When working in a versatile environment where patients belong to different ages groups, one size of chest piece is not enough for maximum efficiency. 

The MDF Procardial comes with three different chest piece attachment ranges from the adult, pediatric, and infant. Although the adult chest piece can be used to diagnose a pediatric patient pediatric chest piece delivers more ease and accuracy for the pediatric patient. And the open bell design is also included on the chest piece if you want to listen to the low-frequency sound.

Maximum Comfort

We all have different ear structures than the other, so one ear tip that one finds comfortable does not mean that others find it the same. Creating one ear tip that everyone finds comfortable is not possible. 

One reliable solution for this is that MDF has chosen, including three ear tips of different sizes. Regular, small, and large so everyone can check which is comfortable for them and creates a better seal.


One incentive MDF provides is their Free-Parts-for-Life program on which you can register on their website. This will allow you to get free replacement parts from them when needed. But you will not need them for some years, and when you do, you can request them, and they will ship them to you. This little gesture gives great confidence to the user when using it.


This model is designed for the versatile environment and the cardiology status of the stethoscope to ensure optimal sound accuracy and sensitivity. Three different ear tip options offer great comfort.


  • Three chest piece sizes
  • Small, regular, and larger ear tips
  • Safety lock on the headset
  • Unique tubing and chest piece


  • The chest piece is bulky and a little heavy

How to Select the Best Stethoscope for lung sounds: 

Buyer Guide

Chest Piece 

The material from which a stethoscope is made can affect the quality of the acoustic. For chest pieces, stainless steel is the standard material. That is why stainless steel chest pieces are more expensive than other materials. Always prefer stainless steel because it will also last longer than others and offers superior acoustic performance. The aluminum chest piece is also a good choice since they are more affordable and lightweight. So what is for you depends upon our preferences.


In tubing, there are two versions; one is called the single lumen, and the other is the dual lumen. The main difference between the dual and single lumen is that dual lumen has a pathway that separates the two channels leading to each ear. The dual lumen offers better sound transmission than the single one.

Also, choose latex-free tubing even if you are not allergic to it because one of your patients might be, and that can be discomforting. Another feature that you should consider is the length of the tubing because you can get tubing ranging from 22 inches to 29 inches.


The acoustic performance of the stethoscope is critical. Choose a stethoscope that offers good acoustic sensitivity. Because if a stethoscope has a better acoustic, you will be able to listen to the faintest sound in the body. Most of the top-quality stethoscopes have reliable acoustics, especially the Littmann and MDF. Cardiology grade is the most high-performance stethoscope category.


Eartips are also an essential factor to consider because they can make your experience good and bad. Most manufacturers offer different ear tips, and you can also buy a replacement for one. Eartips made from soft silicon are often considered comfortable and can create a good seal in the ear.


Do Respiratory Therapists need a stethoscope?

Yes, respiratory therapists need the stethoscope because listening to the lung and heart sounds is a necessary requirement, and a stethoscope is the only tool that can assist with that. Checking the heartbeat and the lung sounds is essential for a respiratory therapist to treat a patient correctly.

What is tunable AFD?

AFD stands for the Adjustable Frequency Diaphragm. It is a very convenient feature that can be found in the diaphragm of the stethoscope that allows you to listen to high and low-frequency sounds by changing the pressure. When you lightly press the chest piece, low-frequency sounds will be captured, while high-frequency sounds will be heard when you firmly press the diaphragm.

Summing Up

Well, here you have it; this detailed review of the best stethoscope for lung sounds will assist you with the decision. Whether you are a student, nurse, or EMT, out of all these stethoscopes on the list, there should be the one that meets your need and the requirement perfectly. We have also included the buying guide so you know what to look for if you are buying your first stethoscope.

Suppose you still find it confusing to choose one stethoscope on the list out of eight. In that case, we will recommend the 3M Littmann Stethoscope, Cardiology IV, which is a cardiology grade stethoscope and has superior acoustic sensitivity that will aid you in making a reliable judgment.
