Noise Cancellation

The noise cancellation is a feature that does not make sense with a stethoscope since we have never usually heard it together because it is mostly found in the headphones, but a stethoscope is a game-changer. 

The digital aspect of the stethoscope makes the most of the thing possible, which can be done with traditional analog stethoscopes. Sometimes, especially in the emergency room, a little noisy background noise can interfere and make it difficult to listen to the body sound. But with the noise cancellation turned on, you will be able to only listen to the desired sound to make a sound judgment.


The advancement in technology opens up many doors of opportunity for many people. The Littman Core digital offers frequency amplification 40 times more than the analog mode. This amplification makes it easy to listen to the faintest to faintest sound. This feature also opens up the door of opportunity for individuals that suffer from hearing loss.

With this amplification feature, there are chances that you don’t miss any sound so that the assessment can be accurate, and so is the judgment based on this information. One feature that makes it a good investment is its ability to work as a digital and analog stethoscope. All you need to do is to toggle the switch on the EKO module. When the switch is flush with the volume button, it is in digital mode. The blinking light will also indicate it. The opposite means it is in analog mode.


Stethoscopes are essential pieces of equipment that medical professionals need, and the smartphone is an item that everyone owns. What would you get if you linked them together? The answer is a stethoscope with the possibility to record the audio, which then can be shared and recode to compare the improvement of the patient.

EKO is a mobile app that can be downloaded for free for android and IOS from their app stores. This app uses Bluetooth to connect with the 3M Littmann Core Digital stethoscope and record the audio sound for up to 120 seconds. You can also show the audio to your other friend or senior for a second opinion. All you need to do is share the audio by adding the recipient email, and they will receive the email from EKO where they can make a simple step account and listen to the shared audio.

With the latest stethoscope version, you can also connect your headphone to the stethoscope by using the app, which can be a useful feature if you use earbuds. 


In our opinion, this stethoscope is ideal for medical professionals that suffer from hearing loss or have a patient at home that needs a daily check. This can also have sufficient features to operate reliability in the critical environment.

2. Cardionics E-Scope 7700 Clinical Model Stethoscope

Cardionics E-Scope 7700 is another electronic stethoscope with an amazing feature that makes it superior to the non-electronic stethoscope. This electronic stethoscope comes with a number of innovative game-changer features since they can detect even the tiniest of sounds for convenient analysis of the patient’s condition. Having the ability to recode and share audio is convenient for teaching. The control on these is also very straight forward which saves from confusion. 

The slim design also makes it useful for long shifts and storage. The ability to amplify as compared to non-electronic stethoscopes makes it more reliable for making an accurate evaluation.

Slim Design

The design of this electronic stethoscope is very slim, especially on the tubing, which takes less space than the other cardiology-grade stethoscope on the market. This design is also easy to wrap around the neck. The chest piece also has three buttons for easy controls. The two-button represented by the + and – symbol is for increasing the volume or, in other words, for amplifying the sound. And the third button with a dot symbol switches between the lungs and the heart sound filters. 

Second Listener

Teaching is an important aspect of being a medical professional, whether you teach the students during the house job or new recruit. One thing that can improve the learning experience is delivering the same information as you are getting from the stethoscope and where to position the chest piece for a specific sound.

With Cardionics E-Scope, this is possible. All you need is a headphone with a micro USB pin that can be connected to the headset of the stethoscope, and you can have a second output for your student to listen to.

You can also record the data and sound by connecting any recording device and can save the audio file on your PC for future comparison of patient recovery. In addition, if you are a medical professional, you might be able to share the data with your doctor or seniors for better assessment.


Most of the stethoscopes come with the adult chest piece. If you are a medical professional who treats a patient of different ages ranging from adult to infant, in that case, you probably know that the adult chest piece does not give the same level of result when checking the infant or pediatric patient.

Cardionics offers three different sizes of the bell, including adult, pediatric, and infant, as well as diaphragms of adult and pediatric to improve both the user experience and the reliability of the judgment. So you don’t need to get a spare stethoscope with an infant or pediatric bell for infant patients; this one will be sufficient.

It is also powered by the standard AAA battery, which is sufficient for four to five months, assuming you use it for 6 days a week for 30 times, which is quite a long time before it needs replacement. 


In our opinion, this stethoscope is a good option for medical professionals that want the stethoscope with amplification and a slim design. Its ability to output audio for the second listener will also come in handy during teaching the students and recording.


  • Slim-line design
  • Micro USB for connecting an extra headphone
  • Filter control for head and lungs sound
  • Three different size bell attachment 


  • Lack the display panel 

3. Eko Duo Stethoscope

Eko is responsible for creating a top-notch electronic stethoscope that is the next evolution of traditional stethoscopes. The Eko Duo is not the only model they created with a digital stethoscope. The most innovative and unique feature they have introduced is the ability to directly connect to your smartphone via Bluetooth. The Eko app gives you the visual display of the sound wave and has two electrodes made of stainless steel for checking the ECG, which will come in handy when treating the patient with heart conditions.

You can either purchase the headset or connect any headphones with them to listen to the audio because there are several settings you can do with these forms to wire to wireless. The insane audio amplification can be useful for everyone.

In terms of aesthetics, Thinklab gives a luxurious feel with a simple yet beautiful indicator to show the volumes and filter levels that will attract attention.

Filters For Clarity 

When listing to the body sound by stethoscope, there are many sounds frequency ranges to low and to higher. For example, the heart sounds usually are in the low-frequency range compared to the lungs, which is why mostly bell is used to detect them.

For more clarity, Thinklab one digital stethoscope offers five different settings so you can listen only to the sound you want to listen to and filter the unnecessary frequencies. This will lead to better judgment. 

When using, you can select between five filters, which you can switch between by pressing the “f” button, which is the top right button of the stethoscope. 

The first filler can detect the low sound frequencies between 30 to 500hz for the heart sound, which is the strong bell mode.
