A New Class Of Clarity

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 amplification* and active noise cancellation can help you auscultate with greater confidence. The 3M Littmann CORE Stethoscope connects with Eko software on a smart device* to visualize, record and share data.

Take Listening To A Whole New Level

The FDA-cleared (US Food and Drug Administration) 3M Littmann CORE Stethoscope toggles between analogue and amplified listening modes so you can listen how you want to during assessments.

Tuneable diaphragm technology lets you hear different frequency sounds by simply adjusting pressure on the chestpiece. Hold the chestpiece with light pressure on the patient in order to hear lower frequency sounds, more pressure allows the user to hear higher frequency sounds. Soft-sealing ear tips conform to individual ears for optimal comfort and excellent sound occlusion.

This 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 and easy to use dashboard. Effectively create and maintain a library of heart sounds to monitor the progressions of a disease, patient condition or even education, this software also allows you to share recordings and data with colleagues.
