Acoustics: A master piece in one movement, designed to let you hear both high and low frequency sounds from a patented single-sided chestpiece. With its innovative design, the Master Cardiology stethoscope is the ultimate in acoustical performance.
Unique Patented Chestpiece:
With just one movement, you can get uninterrupted diagnostic response. With the unique "Master" solid stainless steel chestpiece, you can easily alternate between low and high frequency sounds without moving the chestpiece or operating a switching mechanism. The traditional bell mode and diaphragm mode have been incorporated into the single-sided "Master" chestpiece. For bell mode low frequency monitoring, simply hold the chestpiece in place with light skin contact. For diaphragm mode high frequency monitoring, apply firm pressure on the contoured chestpiece. For an illustration of this, please click here.
Two-tubes-in-one design: Even the tubing has been designed to reduce acoustic artifact. The two tubes are incorporated into a single-tube design that eliminates noise artifact from tubes rubbing together.
Special Procedures Adapter: The Master Cardiology stethoscope comes with a flexible patented Littmann special procedures adaptor designed for auscultation of difficult body sites (such as ankles, neck, wrists, etc.), pediatric patients as well as emaciated patients.
Comfort: The Master Cardiology stethoscope features a non-chill rim and diaphragm assembly. The stethoscope comes with a pair of Littmann Soft-Sealing Eartips designed to assure an excellent acoustical seal in the ear canal and maximum comfort. Also included is an extra pair of firm eartips for your choice of personal fit.
Durability: For long lasting performance, the headset assembly is permanently set at a precise angle. This assures a proper fit, minimizes air leaks and prevents the headset from loosening over time. The polished, durable, lightweight alloy eartubes will not chip or corrode. An extra-strength, internal double-leaf spring is designed to be adjustable so that it will always provide proper tension on the eartubes. The latex free tubing is constructed of a specially-formulated polyvinyl chloride that resists chemical breakdown.
Warranty: The superior performance of the Littmann Master Cardiology stethoscope is backed by a seven year warranty and a lifetime service and repair policy. The warranty is provided by 3M Health Care.

3M™ Littmann® Stethoscopes Tunable Technology
Tunable technology provides convenience, versatility and enhanced acoustics. The dual frequency diaphragm combines both bell (low-frequency) and diaphragm (high frequency) into a single side of the chestpiece. You control bell and diaphragm modes by pressure on the chestpiece rather than by turning it over.
Bell Mode (low-frequency)
For low-frequency sounds, light contact is used on the chestpiece. The diaphragm membrane is contained by a flexible surround that actually suspends it, allowing the membrane to resonate low-frequency sounds.
Diaphragm Mode (high-frequency)
For high-frequency sounds, firm contact pressure is used on the chestpiece. By pressing on the chestpiece, the diaphragm membrane moves inward until it reaches an internal ring. The ring simply restricts the diaphragm membrane's movement. It blocks, or attenuates, low-frequency sound and allows you to hear the higher frequency sounds.
No other stethoscope gives you the same quality and efficiency in auscultation. How? Because 3M has the tunable diaphragm technology which allows you to alternate between low and high-frequency sounds without removing the chestpiece.
