A new class of clarityThe 3M™ Littmann® CORE Digital Stethoscope features the outstanding acoustics, comfort, and quality of a Littmann cardiology-grade stethoscope enhanced by powerful digital technology. Features like up to 40x amplification1 and active noise cancellation can help you auscultate with greater confidence. The 3M Littmann CORE Stethoscope connects with Eko software on a smart device2 to visualize, record and share data.

Take listening to a whole new level

The FDA-cleared 3M Littmann CORE Stethoscope toggles between analog and amplified listening modes so you can listen how you want to during assessments. Tunable diaphragm technology—a 3M invention—lets you hear different frequency sounds by simply adjusting the pressure on the chest piece. Hold the chest piece with light pressure on the patient to hear low-frequency sounds; press a little more to hear higher-frequency sounds. Soft-sealing ear tips conform to individual ears for optimal comfort and excellent sound occlusion.

The 3M Littmann CORE Stethoscope works with Eko software on iOS and Android devices, giving you a HIPAA-compliant means to save and annotate 15, 30, 60, or 120-second recordings in a secure dashboard. Create a library of heart sounds to monitor the progressions of a disease or for education, and securely share recordings with colleagues. The 3M Littmann CORE Stethoscope can be used with Eko Artificial Intelligence to aid in the detection of murmurs.

The 3M Littmann CORE Digital Stethoscope is pre-assembled with a CORE Digital Attachment and a 3M Littmann Cardiology IV Stethoscope. Please visit the respective User Manuals for instructions for use.
