Here’s what makes a stethoscope a 3M™ Littmann® Stethoscope.

Every Littmann stethoscope delivers profession-leading innovations, engineering, advanced materials, precise manufacturing—and a high level of consistent quality that other brands just can’t seem to duplicate.

Our internal testing reveals that some stethoscope brands vary widely, unit to unit, in factors such as sound level, weight, and manufacturing quality. Littmann stethoscopes are built according to strict process and quality controls for tight consistency. That means any Littmann stethoscope you choose will provide a consistently high level of performance.
