3M Littmann Cardiology IV Stethoscope 6156, Tunable Diaphragm, 69 in Plum

The 3M Littmann Cardiology IV Stethoscope is a dual-lumen stethoscope built for clinicians who want strong acoustic performance and versatility. Its single-piece tunable diaphragm lets you move between high- and low-frequency sounds by changing the pressure on the chestpiece.

Designed for adult chest sounds, it delivers clear high-frequency sound with a firm seal. The dual-lumen tubing routes both sound paths within one hose, which helps reduce the rubbing noise common with traditional dual-tube designs.
