The 3M Littmann Cardiologie IV stethoscope is designed for doctors who want superior, outstanding sound quality and a versatile stethoscope (adult and pediatric). It features an innovative design and a single-piece dual-frequency membrane on each side of the horn.

The Littmann Cardiology IV has exceptional acoustics for better listening to high-frequency sounds (adult side, with firm pressure).

Its dual-frequency membrane allows you to listen to high or low frequency sounds by slightly adjusting the pressure on the horn.

Its double tubing combines two sound channels in a single tube, eliminating the frictional noise of traditional double tubes.

Manufactured without the addition of natural latex or plasticizing phthalates, this new generation of tubing lasts longer and is more resistant to skin fluids and alcohol.

The lyre adjusts easily to individual body shapes for optimum comfort. It is aligned with the ear canal.
