The Littmann® CORE Stethoscope is a 3M™ Littmann® Cardiology IV™ Stethoscope that is pre-assembled with the Eko CORE Digital Attachment.

The Eko CORE Digital Attachment can be purchased individually and is compatible with most popular stethoscope models from 3M™ Littmann®, ADC, WelchAllyn, MDF, and Medline with no cutting necessary.

When the Eko App is connected and used with a compatible digital stethoscope, Eko’s FDA-cleared software automatically checks for murmurs and/or AFib during Cardiac Exam or Spot Check. (The Eko DUO ECG + Digital Stethoscope is required for Afib detection).

The Eko App will summarize any findings, including potential murmurs, AFib, or other abnormalities detected. These findings aren’t a diagnosis, but are intended to aid the clinician in reaching a diagnosis accurately, quickly, and confidently.

The Littmann CORE Stethoscope comes with a 2-year warranty which is warranted against any defects in material and workmanship.

All stethoscopes purchased on the Eko website are backed by a 100% refundable, 75-day trial. We offer free returns within 75 days of receiving your stethoscope.
