The 3M™ Littmann™ Master Cardiology Stethoscope provides the best acoustics Littmann stethoscopes offer, with a significant improvement in low-frequency response. With the unique Master chestpiece, you'll get diagnostic information accurately and efficiently.

• The patented tunable diaphragm alternates between low and high frequencies without turning over the chestpiece. This allows for same-site auscultation.
• Two tubes are incorporated into a single-tube design that eliminates noise artifacts created from two tubes rubbing together.
• Includes a flexible patented special procedures adapter designed for auscultation of difficult body sites (such as ankles, neck, wrists, etc.), pediatric and emaciated patients.
• The headset assembly is permanently set at an anatomically correct angle. This assures a proper fit, minimizes air leaks and prevents the headset from loosening over time.
• Patented 3M™ Littmann™ Snap-tight Soft-sealing Eartips assure maximum comfort and excellent acoustical seal.
• Nonchill rim and diaphragm assembly for patient comfort.
