So Glad I bought this!

I love this stethoscope! The tubing and bell are so colorful, I get compliments all the time! The sound quality is amazing. I wish I would've purchased this years ago. I can hear even the faintest sounds when checking patients that have been otherwise difficult to hear.

very satisfied

Pretty, but functional?

I get a lot of compliments on how pretty my stethoscope is. However, in my profession, I pronounce deaths. With that being said, there is a lot of background noise when attempting to listen for a faint heartbeat. I find for every day use it’s great, but I still need to use a different stethoscope in order to cancel out all other bodily sounds at EOL.

Krystal Veitengruber
Not very vibrant

Wonderful sound best stethoscope I’ve ever owned as a nurse. Wish the color was brighter I get asked if it’s a snake or a fish.

Hello. Everything was good with my order except online the color of the Mermaid/Kaleidoscope looked bright and pretty. For some reason once I received it, it looks more black and darker. Which is not that much of a deal.....I just really wanted it to look just like the picture. I've thought about ordering just a plain one to avoid this from reoccurring. However, everything else was good. Thank you.

Hello Corterical!

Thank you for your feedback. We are sorry you are unhappy with your instrument design, let us help you be as proud as you can be with your MDF! Let us know what stethoscope you would like for your exchange and we will be happy to do this for you. Than you for you honest feedback to help us better our products :) Look forward to your reply ! Stay safe <3


The sound is excellent. The colors were not quite as vibrant as I had hoped, but it's still really pretty.

ProCardial® Titanium - Light & Strong


I Am Titanium

Titanium is 45% lighter than stainless steel and has the highest strength-to-density ratio of any metallic element. This is why brilliant engineers use it in race cars, space shuttles, and now stethoscopes.


ProCardial® Titanium

Constructed from lightweight titanium, the MDF® ProCardial® Titanium Stethoscope delivers accurate auscultation of heart, lung, and Korotkoff sounds with acoustic integrity and clarity. Compared to its 9.6oz stainless steel counterpart, our titanium ProCardial® weighs in at only 4.9oz. Imagine what that feels like over a 12 hour shift. With its extra-deep, cone-shaped bell and ultrasensitive diaphragm, this cardiology stethoscope detects the entire frequency range required by cardiologists.

Sound Check 1-2-3

The ProCardial® provides flexibility in assessment, quickly converting to an adult, pediatric (797DDT) or infant (797CCT) stethoscope with its patented screw-on convertible chestpiece.

ProCardial® Titanium - True Bell & True Diaphragm


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 Lock

With our patented Titanium SoundTight™ Glide-Lock-System™ (GLS), we’ve minimized sound loss of this crucial indexing mechanism. Simply push, turn, and the GLS will lock itself into place.

ProCardial® Titanium - Deeper Bell


Sound as a Bell

Our deeper, cone-shaped bell amasses specific low frequency heart sounds, which can often be difficult to distinguish.


Sound Channel

We took the engineering principles used in concert halls and applied it to our stethoscopes. Flat walls create echoes which is why deeply cut baffles are used to reduce sound wave refraction. Using this theory our new C34 tubing has 34 channels etched inside the tube to direct clear and precise sound waves from your patient to your ears.


ProCardial® Titanium - CS34 Acoustic Tubing
ProCardial® Titanium - Denser, Longer Tubing


Sound Barrier

Our flexible, latex-free tubing is thicker and longer than others 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.

 Pat No. ZL 200820155127.0



Sound Design

Our new patent pending STEnT™, permanently attached to the dual-leaf spring, keeps the spring from blocking the opening of the Acoustic Pyramid Chamber™. This ensures a clear and open channel at this important junction.
