The 3M™ Littmann® Classic III™ Stethoscope offers high acoustic sensitivity for excellent performance when doing general physical assessment. Our new design is easier to clean and maintain.

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 chest-piece. Unlike two-sided models, there’s no need to turn over and reposition the chest-piece. Hold the chest-piece 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 ear-tubes. Snap-tight, soft-sealing ear-tips conform to individual ears for an excellent acoustic seal and comfortable fit. Ear-tips snap firmly onto the ends of the ear-tubes 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. It provides longer stethoscope 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. And, to play its part in the protection of human health and the environment, the next-generation tubing does not contain phthalate plasticizers. The Master Cardiology stethoscope is made in the USA for consistent quality. It comes complete with large and small soft-sealing ear-tips, large firm ear-tips, Special Procedures Adapter, and instructions.
