The 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 analogue 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 Digital Stethoscope is pre-assembled with a CORE Digital Attachment and a 3M Littmann Cardiology IV Stethoscope.
