The 3M Littmann Master Cardiology Stethoscope is characterized by the best acoustic response in the Littmann mechanical stethoscope line; with a tunable diaphragm, dual-lumen tubing, and a precision, ergonomically designed, stainless steel chestpiece.
The Master Cardiology Stethoscope features tunable diaphragm technology—a 3M invention—that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two-sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.
Outstanding acoustics, the highest in Littmann mechanical stethoscopes.
Tunable diaphragm: Hear high or low frequency sounds by slightly adjusting pressure on the chestpiece.
Dual-lumen tubing: Two sound paths in one tube eliminates the rubbing noise of traditional double tubes.
Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.
Includes Special Procedures Adaptor for pediatric or neonatal auscultation.
10 out of 10 acoustic performance rating.
7 year warranty, made in the USA.

Shipping was quick. The master cardiology provides excellent sound quality and comes in a variety of colors. Engraving is neat and well done.

I purchased this stethoscope as a graduation present for my daughter. She was thrilled with the clarity and the overall look. Shipping was fast. I have ordered several times from this company, and you can't go wrong.

My stethoscope took about a week to arrive after ordering, and came packaged well. The colors are a little misleading on the pictures vs what you receive in real life, but I still love it! I ordered Caribbean blue, and it is a little darker green than expected, but still a nice color. The sound when auscultations it remarkable compared to my classic Littmann I have had for 7 years. I am so happy I splurged and spent the extra money to get the top of the lines because this stethoscope is like night and day with my old one! No more diminished lung sounds for me!

Have been in EMS for 34 years and have had several Littman stethoscopes. My last was a cardiology III. Ordered the master cardiology this time. The ability to hear all sounds are amazing. Would recommend to buy.

My stethoscope arrived right away. The engraving turned out great. This is my second Littman stethoscope. I decided to upgrade to the master.

Extremely pleased. I ordered this on a Monday and received it by Wednesday and that’s with me getting it engraved.

My littman cardiology III that I received in nursing school a decade ago up and grew some legs. I decided to go with the master cardiology because it looks awesome and is reviewed well. Sound quality leaps and bounds ahead of my old cardiology III. It arrived quickly. The engraving is even and sharp looking. I am quite pleased with it and my service.

I love my master cardiology stethoscope. It arrived as expected. The engraving is nice and I love the sound quality. I needed to replace my other Littmann class 111.

Love my Master Cardiology stethoscope! My prior stethoscope was 25 years old and finally gave out! Couldn't be happier! The plum color is stunning!

Engraving is beautiful and the tubing is great. Like it much more than my electronic Littman that keeps shorting out every time I place it on a patient's chest. That one was very disappointing and it started a few months after I got it.
