3M™ Littmann® Master Cardiology™ Stethoscope 
  • Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.
  • Outstanding acoustics: The highest in Littmann mechanical stethoscopes.
  • Tunable diaphragm: Hear high or low frequency sounds by slightly adjusting pressure on the chestpiece.
  • Dual-lumen tubing: Two sound paths in one tube eliminates the rubbing noise of traditional double tubes.

The 3M™ Littmann® Master Cardiology™  stethoscope line’s greatest acoustic response, a tunable diaphragm, dual-lumen tubing, and a precisely crafted, ergonomically contoured stainless steel chestpiece define the stethoscope.

The 3M™ Littmann® Master Cardiology™ Stethoscope features tunable diaphragm technology—a 3M invention—that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time saving feature allows the healthcare provider to focus on the patient, while the non chill rim provides patient comfort.

Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap tight, soft sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.

Next-generation resilient tubing maintains its flexibility and shape even after being folded tightly into a pocket. Due to better resistance to skin oils and alcohol, it prolongs the life of the stethoscope and is less likely to pick up stains. The benefit for sensitive medical professionals and their patients is that next generation tubing is not constructed with natural rubber latex. Additionally, the next-generation tubing does not contain phthalate plasticizers in order to contribute to the preservation of human health and the environment.
