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.

I ordered a Littman Master Cardiology after my last stethoscope just decided it had had enough!! This new one is fantastic!! It is lightweight and I can hear even better which I though was impossible! As an NP it makes sure I hear the faintest breath sounds and heart murmurs. I got this one inscribed and it was perfect!

Very fast shipment even with the engraving. Price was great as well! Littman quality is uncanny. I have used my previous stethoscope for over 10 years of merely daily use, and anticipate that this one will be no different! Thanks!

I ordered this stethoscope for my daughter who is a veterinarian. The ordering process was easy, offering the best price I could find and an engraving ability better than any other site out there. I received the stethoscope so quickly in the original packaging with the specific, perfect engraving I chose. My daughter loves it! I am extremely happy with the service and product I received!! I will definitely order and recommend mystethoscope.com to all of my friends and family!!

Arrived in great time and my friend LOVED it! She missed the engraving I added on her first look, but when she discovered it, it was icing on the cake!

Great! I can hear clearly on my patients. I am very confident in using this now that I feel I can hear better. I work on a med-surg/Tele floor so this is perfect!

I formerly was using the cardiology 3 however my tubing was cracking and I have been interested in the master cardiology for a few months now so I purchased the black with smoke finish (So classy by the way!). I opted for engraving on the head of the stethoscope which turned out beautiful and did not impact the quick shipping. When the stethoscope arrived of course I had to try it on myself, the sound was amazing. I am a RN who works on an ICU-ICU stepdown floor for the adult population. This stethoscope was the perfect fit for me and my patients. The single sided chest piece is comfortable for my hand and the accustics are notably better than my cardiology 3. Very impressed with this stethoscope so far, I am looking forward to seeing how well the quality holds with time. Highly recommend purchasing from this site.

We ordered two stethoscopes; one for my daughter going into the physicians assistant program and one for my daughter-in-law as a thank you gift for helping to care for my husband with his terminal illness. Your stethoscopes are their top choice so we wanted to get the best we could! They came quickly and the engraving is very personal and done professionally. We are thrilled with your product!! Thank you❤️

Fast shipping and easy ordering process. The stethoscope itself is a great upgrade from my old Littman and I look forward to many years of service from it.

Great ordering process, arrived in fine shape. I'm getting pretty old, so the reported acoustic performance was the deciding factor for me. I haven't used it outside the house yet (I'm a rural EMT), but it seems like a dandy scope. The tunable diaphragm feature seems like a winner. Thanks!

I LOVE this stethoscope. I’ve had one in this past and enjoyed using using it. I’ve found the auscultation on this to be better/ higher quality than the cardiology IV, even though the cardiology IV is a really good stethoscope.
