What is the difference between the 3M™ Littmann® CORE Digital Stethoscope and the CORE Digital Attachment?

The Littmann CORE Digital Stethoscope is the most advanced Littmann Stethoscope yet. It comes pre-assembled with a 3M™ Littmann® Cardiology IV™ Stethoscope and a CORE Digital Attachment, giving it the ability to perform in both digital and analog modes.
Alternatively, the CORE Digital Attachment is sold separately. It is not a stethoscope by itself but can be manually added to a Littmann Cardiology IV™ Stethoscope.

[H3]
What is the difference between the 3M™ Littmann® CORE Digital Stethoscope and other digital stethoscopes?

A key functionality of the Littmann CORE digital stethoscope is that it can continue to operate as a cardiology-grade stethoscope even when the digital component is turned off.
The Littmann CORE digital stethoscope is produced by Littmann stethoscopes and is composed of a Littmann Cardiology IV™ Stethoscope and a CORE Digital Attachment, enabling both digital and analog capabilities.

[H3]
Why purchase the 3M™ Littmann® CORE Digital Stethoscope?

The Littmann CORE Digital Stethoscope comes preassembled for your convenience and is tested to ensure proper setup. It offers the superior acoustics, comfort, and quality of the Littmann Cardiology IV™ Stethoscope, plus the added benefit of up to 40x amplification (at peak frequency, vs. analog mode), active noise cancellation, and sound wave visualization using a companion app on a mobile device.
In addition, in certain geographies including the United States, the Eko App enables the use of Eko’s subscription-based, FDA-cleared software features to detect the presence of suspected murmurs. You can also create, save, and share recordings (requires an Eko+ membership).
When you purchase the Littmann CORE Digital Stethoscope, we ensure proper assembly, and you receive a single point of service and support from Littmann.

[H3]
Does the Littmann CORE Digital Stethoscope contain latex?

No, the Littmann CORE digital stethoscope uses next generation tubing that does not contain natural rubber latex or phthalate plasticizers.

How do I turn the Littmann CORE Digital Stethoscope on and off?

When the Littmann CORE digital stethoscope is off, it functions as a mechanical (analog, not amplified) stethoscope. To turn the Littmann CORE digital stethoscope amplified mode on, press the power toggle in. The LED light will begin flashing. You will now hear amplified and filtered sound in the eartips. The CORE digital unit LED light provides information about the status of the device:

a. Flashing white: Unit is ON and ready to pair with the Eko mobile app. (You do not need to pair Bluetooth® with the app for the amplification to work. You need to pair with the app to view sound wave visualization and use features such as sound recording, sharing, and AI-enabled screening.)

b. Solid white: Unit is ON and paired to the Eko App.
c. Yellow: Unit is plugged in and charging.

d. Flashing Yellow: LOW battery.

e. Green: Unit is plugged in and fully charged.

(Note: The CORE digital unit will not function while it is charging.)

[H3]
I turned my stethoscope on and now it appears to be off. What happened?

The Littmann CORE digital stethoscope will go into standby mode after 5 minutes of inactivity. To turn the device back on, toggle the power off and back on.

[H3]
How do I connect the Littmann CORE Digital Stethoscope to my mobile device?

Download the Eko App from the Apple App Store® or Google Play™ Store, start the app, and create an Eko account. Turn on Bluetooth® on your phone or tablet, launch the Eko App, and turn on the Littmann CORE digital stethoscope. Then pair the stethoscope with your device as instructed in the app.

[H3]
Is the Eko App available in different languages?

Yes, English and Japanese are available on all platforms. Spanish, German, French, Portuguese, and Italian are available now on Android™ and will be available on iOS in the future. More languages will be added to both platforms in the future.

[H3]
Is my data secure in the Eko App?

There is no data stored in the app. The app acts as an interface between the web platform and your data. Eko’s app is a cloud-based software with all data stored in the cloud within the United States. Data security is one of our highest priorities. Eko maintains HIPAA-compliant policies, procedures, and technical safeguards for patient and customer data. Eko uses HIPAA-compliant and NIST recommended 256-bit AES encryption using managed keys for patient data. Encrypted backups are taken daily. Eko’s app also meets the General Data Protection Regulation (GDPR) in the EU.

[H3]
What phones is the new Eko App compatible with?

The new app is compatible with iOS version 15 or newer and will not work on iPhones using iOS 14 or older. For those using iOS 14 or older, the app will not update to the new app, but you can continue to use the previous version of the Eko app. To see a complete list of compatible Android devices, please visit the Eko Help Center.

[H3]
How do I know if I’m using my 3M™ Littmann® CORE Digital Stethoscope correctly?

1. Rotate to the correct side – when using the double-sided Littmann CORE digital stethoscope, you need to open (or index) the side you want to use—bell or diaphragm—by rotating the chestpiece. If the diaphragm is open, the bell will be closed, preventing sound from coming in through the bell and vice versa.

2. Point eartips forward - before placing the eartips in your ears, make sure they point forward, away from you. This ensures that the eartubes will align with your ear canals for comfort and maximum sound transmission.

3. Choose your eartip size - for optimal acoustic performance, it’s important to use the eartip size that best fits comfortably in your ear to achieve a proper seal. Small and large size eartips are provided in the Littmann CORE Digital Stethoscope box. You may also perform a headset adjustment to suit your personal preference for comfort.

4. Remove potential obstructions - if you usually carry your Littmann CORE digital stethoscope in a pocket, or don’t clean it often, lint or dirt may accumulate and obstruct the sound pathway. To prevent debris from accumulating, give your stethoscope routine cleaning and care, and keep the open bell free of debris by covering it with the removable diaphragm.

5. Check the seal – Littmann CORE digital stethoscopes rely on an airtight seal in order to transmit body sounds from the patient to the practitioner’s ears. Loose parts in the chestpiece, loose or cracked tubing, or improperly seated eartips can prevent an airtight seal.

[H3]
How do I ensure optimal sound quality while listening?

If possible, perform auscultation in a quiet environment. While the Littmann CORE digital stethoscope has active noise cancellation, some environmental noise will still be audible during auscultation.

Tunable diaphragm technology was invented by 3M Health Care, now Solventum. It allows you to hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece with light pressure on the patient’s chest to hear low frequency sounds; press a little more firmly to hear higher frequency sounds.

If using the Eko App and external speakers or headphones to listen live, we recommend using plug-in speakers or headphones for best sound quality. Wireless headphones may yield varied sound quality. Please visit the Eko Help Center for more information.

[H3]
How do I ensure optimal sound quality when listening in playback mode?

You may be able to listen to sounds via Bluetooth® headphones by pairing your Littmann CORE digital stethoscope to the Eko App on your mobile device, using the ‘Play from Headphones’ feature in the Eko App on your mobile device and then listening live via Bluetooth® through the app. The Littmann CORE digital stethoscope does not pair directly with Bluetooth® wireless headphones.

If using the Eko App and external speakers or headphones to listen live, we recommend using plug-in speakers or headphones for best sound quality. Wireless headphones may yield varied sound quality. Please visit the Eko Help Center for more information.

Why purchase the 3M™ Littmann® Cardiology IV™ Stethoscope?

There’s a reason seasoned doctors, nurses, and clinicians know that Littmann Stethoscopes are synonymous with professionalism, excellent acoustics and dependability. It’s because quality is at the core of what we do, and when it comes to choosing a stethoscope, there’s no comparison. There’s a name in auscultation you can count on—just look for the L.
Hear the Hard Stuff: Littmann Cardiology IV stethoscopes are more than twice as loud as the next leading stethoscope, allowing you to more reliably and consistently hear heart sounds at lower frequencies (below 120Hz) like Korotkoff sounds, Mitral Stenosis and S3 and S4 Gallops when compared to other leading stethoscopes.*
Handcrafted Quality: Littmann Cardiology IV stethoscopes are designed and manufactured in the United States with globally sourced materials following rigorous processes and strict controls. The result? Littmann Cardiology IV stethoscopes are reliably louder than other stethoscopes.*
Confidence and Comfort: Littmann Cardiology IV stethoscopes let you confidently assess, monitor and diagnose patients with outstanding acoustics that help you hear subtle sounds other stethoscopes may miss. They are also lighter than other stethoscopes**, providing enhanced all-day comfort.

* Based on tests of the 3M™ Littmann® Cardiology IV™ Stethoscope and 3M™ Littmann® Classic III™ Stethoscope against globally-available comparable stethoscopes in an equivalent class using recorded heart sounds with diaphragm.
** Based on published weights of globally-available comparable stethoscopes in an equivalent class.

[H3]
Does the Littmann Cardiology IV Stethoscope contain latex?

No, the Littmann Cardiology IV Stethoscope uses Next Generation Tubing that does not contain natural rubber latex or phthalate plasticizers. This includes select models featuring innovative satin finish tubing that is less likely to stick to hair and clothing.

[H3]
What is the price of a Littmann Cardiology IV Stethoscope?

Littmann Cardiology IV Stethoscopes are sold through authorized dealers who set their own pricing and may occasionally have special promotions and offers.
We encourage you to stay in touch by signing up for Littmann email newsletters and following Littmann on social media to be among the first to know about special offers and promotions.

[H3]
Can the Littmann Cardiology IV Stethoscope be engraved?

Yes, the Littmann Cardiology IV stethoscope can be laser engraved, and many of our authorized dealers offer this service. We do not recommend scratch engraving as this can increase frictional noise during auscultation. Do not disassemble the stethoscope in any way (e.g., pulling the tubing apart, unscrewing the tubing stems).

What is unique about satin finish tubing?

Our satin finish tubing formula used on select Littmann Cardiology IV Stethoscope models provides a more comfortable, flexible feel that is less likely to stick to hair or clothing.

The satin finish also offers a more flexible feel for easier folding and stowing of your cardiology-grade stethoscope, so you can keep it with you between patients. Its specially formulated coating is easy to clean, with debris- and scratch-resistance to preserve the look and life of your stethoscope.

Littmann Cardiology IV Stethoscopes with satin finish tubing are available in two colors, Alabaster and Midnight Blue.

Please sign up to receive Littmann emails or follow us on social media to be one of the first to know when we launch new styles.

What are the advantages of using the Littmann Cardiology IV Stethoscope’s tunable diaphragm?

The tunable diaphragm is a 3M invention that allows you to listen to both low and high frequency sounds without the need to remove the chestpiece from the patient, turn it over, and reposition it.

By varying the pressure placed on the patient, a tunable diaphragm will adjust, or tune, the sounds to allow you to hear either low or high frequencies. When holding the tunable diaphragm on a patient and pressing lightly, low frequency sounds will be transmitted. When using the tunable diaphragm and pressing firmly, higher frequency sounds will be emphasized.

How do I clean my Littmann Cardiology IV Stethoscope? Can I sterilize it?

We recommend cleaning external parts between patient exams using 70% isopropyl alcohol wipes, and do not use hand sanitizer as a cleaning agent as there are additives that may damage parts of the stethoscope.

To prevent stethoscope damage, do not immerse your stethoscope in any liquid, subject your stethoscope to any sterilization process (e.g., autoclaving, liquid chemical sterilization), or store in extreme heat.

The diaphragms, non-chill bell sleeve, and eartips may be removed, if necessary, for thorough cleaning. Ensure all parts and surfaces are dry before reassembly. To remove an eartip, grasp the eartip firmly using the thumb and forefinger of one hand and pull sharply away from the eartube while holding the eartube in the other hand. To attach the eartips, push the small side firmly onto the eartube until it snaps fully into p
