The 3M™ Littmann® Cardiology IV™ Stethoscope is designed for healthcare professionals who require exceptional acoustic performance combined with exceptional versatility. Its innovative design provides a one-piece synoptic diaphragm on each side of the hood.

The 3M™ Littmann® Cardiology IV™ Stethoscope is the next generation of one of the most recognized stethoscopes in the profession, offering improved acoustic performance with improved audibility of high frequency sounds (adult side, firm pressure). It features a distinctive bell shape and tunable diaphragms on both sides to offer exceptional acoustic performance, diagnostic versatility, and convenience for treating adult and pediatric patients. The pediatric side of the hood is converted to a traditional open hood by removing the tunable diaphragm and replacing it with an included chill remover ring. Both the adult and pediatric sides have a one-piece diaphragm that is easy to remove, attach and clean because the surface is smooth and without cracks. Tunable diaphragm technology, a 3M™ invention, allows healthcare professionals to hear sounds of different frequencies simply by adjusting the pressure on the part.

Headphone tension is easily adjusted for head size. Tight seal ear plugs conform to individual ears for excellent acoustic sealing and a comfortable fit. Dual lumen tubes combine two sound paths in one tube, eliminating the rubbing noise that traditional dual tubes create. This feature makes it possible for the professional to hear the sounds of the patient with less interference.

The new generation tube retains its shape and flexibility even after folding a pocket. Provides longer stethoscope life due to the skin's improved resistance to oils and alcohol, and is less likely to stain or discolor. The new generation of tubes is not made from natural rubber latex, a benefit for sensitive physicians and their patients. And, to play its role in protecting human health and the environment, the new generation of tubes is not made with phthalate plasticizers.

The Cardiology IV™ Stethoscope is manufactured in the United States and is warranted for seven years. Comes complete with large and small olives and chill ring. Our stethoscopes are used by millions of medical professionals around the world who are dedicated to achieving the best results for patients. Wearing a Littmann® stethoscope is an expression of your commitment to medicine and personal success.
