Littmann Master Cardiology Stethoscope: All Black 2161

• 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.
• Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.

The 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. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds.

 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.

Resilient next generation tubing retains its shape and flexibility even after folding tightly into a pocket. And, to play its part in the protection of human health and the environment, the next generation tubing does not contain phthalate plasticizers.
