Sound quality so exceptional, you might never go back to your old stethoscope.

The 3M Littmann Electronic Stethoscope Model 3100's exceptional sound capabilities deliver an exceptional auscultation experience. Clinical evidence shows that it's easier to detect difficult-to-hear heart sounds, like S3 gallops, aortic regurgitation murmurs, and abnormal lung sounds. Here's why:

State-of-the-Art Sound Sensor

• Built to stringent specifications, it provides a life-like 3M Littmann sound experience equivalent to a high-end cardiology stethoscope.

Proprietary Ambient Noise Reduction Technology

• Proprietary technology reduces, on average, 85% of ambient background noise that can interfere with the auscultation experience.

Frictional Noise Reduction Technology

• A number of subtle design changes in the chestpiece help reduce handling noises compared to earlier electronic stethoscopes. It's less distracting. So it helps you focus more on what you need to hear.

Up to 24X Sound Amplification

• Extra listening power for those times when you need it: may be helpful when a heart, lung or body sound is especially faint; when a patient is obese; or when a patient's clothing restricts your listening experience.
