Classic tone, modern mastery.
Blending powerful acoustics with a refined, vintage-inspired look, the Littmann Stethoscope Master Cardiology Black with Brass Finish is where timeless style meets uncompromising performance.
With 3M’s signature Tunable Diaphragm Technology, the Littmann Master Cardiology Brass Edition lets you switch between high and low-frequency sounds by simply adjusting pressure—no flipping required, no time wasted. Every sound is captured with sharp definition, making it easier to detect subtle changes in heart, lung, and bowel activity.
Its black dual-lumen tubing reduces extraneous noise and ensures smooth, uninterrupted auscultation. Built to withstand daily use, it resists skin oils, stains, and alcohol—maintaining flexibility and performance over time.
For added comfort, the Snap-Tight Soft-Sealing Eartips provide a custom acoustic seal, while the headset adjusts easily for a personalized fit. Included with every Littmann Master Cardiology Brass Edition is a Special Procedures Adapter, ideal for neonatal or hard-to-reach exams.
Proudly made in the USA and backed by a 7-year warranty, this stethoscope is built for professionals who take pride in precision—and in presentation.

This Littmann Master Cardiology is simply outstanding. The sound quality is crystal clear, making it easy to catch even the most subtle heart and lung sounds. The black tubing paired with the brass finish looks so elegant and professional — I’ve already received compliments from colleagues. It feels comfortable to use during long shifts and has a solid, premium build that gives me confidence it will last for years. Definitely worth the investment!

The finish gives it a very premium look, but what I appreciate more is how sturdy and reliable it feels in daily use. The single-sided chestpiece design is very convenient, and it sits comfortably without feeling bulky.
