The 3M Littmann Cardiology IV is the stethoscope of choice for cardiologists, pulmonologists, critical care physicians, and any clinician who needs to hear what others miss. It delivers the highest acoustic performance of any dual-sided Littmann stethoscope — built around a distinctive chalice-shaped chestpiece that concentrates and amplifies sound with exceptional clarity.

Both the adult and pediatric sides feature tunable diaphragm technology — apply light pressure for low-frequency sounds (S3 gallops, murmurs), firm pressure for high-frequency sounds (breath sounds, bowel sounds). The pediatric side converts to an open bell by removing the diaphragm and attaching the included non-chill bell sleeve — giving you full diagnostic range in a single instrument.

The dual-lumen single tube eliminates the rubbing noise of traditional double tubes, delivering cleaner sound transmission. Next-generation tubing resists skin oils, alcohol, and staining, holds its shape after being pocketed, and is latex-free with no phthalate plasticizers.
