The 3M™ Littmann® Classic III™ Stethoscope takes medical listening to the next level. Designed for both students and experienced healthcare professionals, it delivers outstanding acoustic sensitivity and a dual-sided chestpiece for listening to heart, lung, and other body sounds with precision. Whether you’re performing a physical exam or monitoring a patient’s condition, the Classic III ensures accurate sound detection and reliable performance.

Tunable Diaphragm Technology

A 3M™ innovation, the tunable diaphragm allows you to hear different frequency sounds simply by adjusting the pressure on the chestpiece:

• Apply light pressure to capture low-frequency sounds.

• Press a bit firmer to detect high-frequency sounds.
  This feature saves time, enhances accuracy, and ensures patient comfort thanks to the non-chill rim.

Designed for Comfort

The headset tension can be easily adjusted for a perfect fit—just squeeze or pull the ear tubes to suit your preference. The snap-tight, soft-sealing ear tips create an excellent acoustic seal while remaining comfortable during long use.

Built for Durability

Manufactured in the USA using globally sourced materials, the Classic III features next-generation tubing that maintains flexibility and shape even after being stored in pockets. The tubing resists skin oils and alcohol, helping extend the stethoscope’s lifespan. It’s also latex-free and phthalate-free, making it safe for sensitive users and eco-friendly.

Each stethoscope comes with:

• Large and small soft-sealing ear tips

• Non-chill bell sleeve

• User instructions

Hear What Others Miss

The Classic III offers twice the acoustic performance of many competing stethoscopes, especially for low-frequency sounds (below 120 Hz) such as heart murmurs, gallops (S3, S4), and Korotkoff sounds. This makes it easier to identify subtle heart and lung irregularities with confidence.

Comfortable for All Patients

Thanks to its dual-sided chestpiece, the Classic III can be used on both adult and pediatric patients. The open or closed bell design allows seamless switching between modes, helping clinicians provide more comfortable and accurate examinations.

Perfect for Learning and Practice

With high acoustic sensitivity, the Littmann® Classic III™ helps medical students and professionals refine their auscultation skills. It’s a trusted companion for learning accurate diagnosis and patient assessment techniques.
