Littmann Master Cardiology Stethoscope is characterised by the best acoustic response in the Littmann mechanical stethoscope line; with a tunable diaphragm, dual lumen tubing, and a precision, ergonomically designed, stainless steel chestpiece. It features a 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 is 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.

Resilient next-generation tubing retains its shape and flexibility even after being folded tightly into a pocket. It provides longer shelf life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next-generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. Also, to play its part in the protection of human health and the environment, the next-generation tubing does not contain phthalate plasticizers.

Littman Master Cardiology Stethoscope is made in the USA for consistent quality. It comes complete with large and small soft-sealing eartips, large firm eartips, Special Procedures Adapter, and instructions.
