If possible, perform auscultation in a quiet environment. Our proprietary 3M tunable diaphragm technology lets you 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.

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.

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.
Littmann Cardiology IV Stethoscopes are sold through authorized dealers who set their own pricing and may occasionally have special promotions and offers.

Below are five essential tips for using your Littmann Cardiology IV Stethoscope properly and ensuring optimal audio quality.
1. Rotate to the correct side – when using the double-sided Littmann Cardiology IV 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, toward your nose. 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 Cardiology IV Stethoscope box. You may also perform a headset adjustment (as shown below) to suit your personal preference for comfort.
4. Remove potential obstructions - if you usually carry your Littmann Cardiology IV 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. This is also true for models featuring satin finish tubing.
5. Check the seal – Littmann Cardiology IV 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.
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).

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.

No, because the Littmann Cardiology IV Stethoscope contains metal.
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.
No, we only recommend using the 3M™ Littmann® Classic II Infant Stethoscope on neonatal patients. However, some neonatal specialists report that the diameter of the bell and diaphragm on that model is still too large to get good surface contact on neonates.
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 place. To prevent ear canal injury, be sure eartips are firmly attached to the headset before inserting them into your ears.
Yes, Littmann Cardiology IV Stethoscope eartips snap firmly onto the ends of the eartubes and can be removed for cleaning, but may require significant effort to remove. This design is intentional for safety purposes.
The tubing used on the Littmann Cardiology IV Stethoscope is made of PVC (polyvinylchloride), which becomes hard when exposed for long periods of time to the lipids found in human skin. If worn around the neck, we recommend wearing the stethoscope over a collar away from contact with your skin. Models featuring satin finish tubing are unlikely to encounter these problems, but please contact us with any questions or concerns.
