In short…
- What makes Littmann stethoscopes special: All models offer high acoustic sensitivity with tunable diaphragms that let users hear both low and high-frequency sounds.
- Noise control and sound clarity: Tunable diaphragm technology also helps reduce ambient noise, allowing clinicians to focus on critical body sounds, even in noisy environments.
Whether you’re a nurse, a doctor or a student, there’s a 3M™ Littmann ® Stethoscope that’s right for you. Each stethoscope in the Littmann range has been designed to be lightweight and comfortable, with earpieces that fit easily into your ears and unique tunable diaphragms to amplify the most subtle heart sounds.

Hear the difference
All Littmann stethoscopes provide high acoustic sensitivity and excellent performance. They are precision engineered through rigorous process and quality control to ensure consistently high levels of performance. Innovative technology features provide enhanced acoustics, enabling you to pick up the tiniest of sounds. They are all fitted with patented tunable diaphragms that allow you to hear different frequencies through the same stethoscope. The tunable diaphragm technology provides frequency-specific attenuation of ambient noise, so you can listen to the patient, not their environment.
See the difference
Stethoscopes with rigid tubes can kink or bend, pulling on the earbuds and making them difficult to use. 3M™ Littmann® Stethoscope Tubes hang straight and bend easily. Additionally, 3M™ Littmann® chest pieces are available in a variety of finishes to suit your personal style.
Feel the difference
3M™ Littmann® Stethoscopes provide enhanced comfort for you and your patients: Soft-sealed snap-on eartips fit comfortably in the ear, and the cold-resistant bell sleeve insulates the steel open bell from the skin to help build a more meaningful doctor-patient relationship.
