MDF Stethoscopes

The MDF® MD One® stethoscope is a premier diagnostic instrument, known for its performance, durability and aesthetics. Constructed from acoustically-superior stainless steel, MD One® delivers accurate auscultation of heart, lung and Korotkoff sounds with acoustics integrity and clarity, while its ergonomic design ensures comfort over longer shifts.

Sound Judgement

Take the guesswork out of auscultation with our True Bell & True Diaphragm dual-head chestpiece. The bell side focuses on low frequency sounds (20Hz-100Hz) while the Ultra-sensitive Diaphragm handles high frequencies (100Hz-1000Hz).

Sound Barrier

Our flexible, latex-free tubing is thicker and longer to block out external noises, and provide a safer distance between you and your patient.

Sound Fit

Our patented ErgonoMax™ headset is pre-angled and tension adjustable, allowing for a tailored fit. The dual-leaf spring adds a second layer of durability, ensuring the structural integrity of the headset and prevents breaking when tension is increased.

Sound Design

Our Acoustic Pyramid Chamber™ keeps the stethoscope tube from kinking or compressing while you work around your patient, to ensure a clear and open channel.


Safe & Sound

Our patented SafetyLock™ prevents accidental puncturing of the eardrum from loose eartips coming off during your practice.

Sounds Comfy

Our ComfortSeal™ eartips provide you with the perfect fit. All MDF® stethoscopes come with 3 sizes of eartips in small, medium, and large. Pliable silicone material allows the eartip to compress slightly creating a better sound seal.

Sound Mark

Laser engrave the chestpiece with a message of your choice, making it easy to identify and personalize for you, or a loved one.
