3M Littmann CORE Digital Stethoscope 8480

Overview

Not a purely acoustic stethoscope, the Littmann CORE pairs cardiology-grade analog acoustics with digital amplification and active noise cancellation. A toggle switches between listening modes, and Eko software on a phone or tablet visualizes, records and shares heart sounds.

Clinicians facing faint heart sounds or noisy rooms gain the most from the amplified mode and noise cancellation, while the analog setting remains for routine checks. Recording and sharing through Eko suit teaching and following a patient over time. Some features require a subscription, and the smart device is not in the box.

Who it's for

Clinicians who struggle with faint heart sounds or loud surroundings, and educators building a library of recordings, get the most here. Someone who only needs routine acoustic listening will carry electronics they never use.

Pros and cons

Performance notes

Amplification peaks at one frequency, so the gain on other sounds is smaller. Pressure on the tunable diaphragm decides what you hear: light contact brings out low frequency sounds and firmer contact brings out higher ones. Noise cancellation and the sealing ear tips work together to cut room sound reaching the ears.
