The 3M Littmann Cardiology IV Stethoscope is the next generation of one of the most recognized stethoscopes in the profession, offering improved acoustic performance with better audibility of high-frequency sounds (adult side, firm pressure). Its distinctive chalice-shaped chestpiece features tunable diaphragms on both sides to deliver outstanding acoustic performance, diagnostic versatility, and convenience for treating adult and pediatric patients. The pediatric side of the chestpiece converts to a traditional open bell by removing the tunable diaphragm and replacing it with the included non-chill bell sleeve.
The Cardiology IV stethoscope isn’t just for cardiologists. It is used by specialists and general practice physicians, critical care nurses, EMTs, medical students, and other healthcare professionals to identify, listen to, and study cardiac, lung, and other body sounds in adult and pediatric patients.
Outstanding acoustics with better audibility of high-frequency sounds (adult side, firm pressure).
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.
Next-generation tubing lasts longer and resists stains. Not made with natural rubber latex or phthalate plasticizers.
Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.
9 out of 10 acoustic performance rating.
7 year warranty, made in the USA.

The product arrived on time and well packaged. The Cardiology IV is a nice device and definite upgrade over my Cardiology II. I can hear much more detailed sounds and I like the dual adult/pediatric chest piece. Pricing was comparable to other sites. Would definitely buy from this site again.

I ordered a stethoscope for a gift and the ordering process was very easy. They have so many styles and colors to choose from and I love that they offer engraving. I received the stethoscope on time without any difficulty.
I accidentally placed my order twice, so I had to contact customer service. She was friendly and reversed the mistake within a matter of minutes.
I will definitely use them the next time I am in need of a stethoscope.

I just replaced my littman classic III for this new cardiology IV stethoscope and I can't say enough about what a difference it makes! My other stethoscope was 6 years old and the tubing was so stiff. This stethoscope is the perfect length to wear around your neck, the bell turns effortlessly and the tubing is so flexible. I can hear 20x better with this stethoscope even in patients that are unable to take deep breaths. Heart sounds are so much more amplified with this stethoscope and heard easily! Definitely a great purchase!

I love my new Cardiology IV stethoscope. The sound is much better than my old Classics II. I chose the color raspberry, and it is so pretty. Stands out so if left on a desk I can spot it a mile away. The engraving was very nice, too.

I am impressed by the difference of sound quality between my old stethoscope and the Littmann Cardiology IV. I can hear heart and lung sounds much more clearly with my new Littmann.

I bought the Littman Cardiology IV stethoscope. Great acoustics! I can hear an apical pulse well on a heavier person as well as through a shirt if needed. I have chronic neck pain and the weight of this stethoscope hasn't bothered my neck at all. Easy ordering process and very comparable price. I'd definitely order with MyStethescope company again.

I bought the Littmann Cardiology IV 27" stethoscope. Great acoustics. I can even hear an apical pulse well on a heavier person as well as through a shirt. I have chronic neck pain and the weight of this stethoscope hasn't bothered my neck at all. Very pleased with the ease of ordering and the product received from MyStethescope! Thank you!

Awesome. Excellent product. You can hear everything. My friend used mines and she had to order herself one the same day.

The stethoscope arrived 3 days earlier than the tracking number indicated. I took it to work that day, and the performance over my Littman Classic III, made it so I was totally glad I upgraded. I am hearing things on my Cardiology unit that I was not hearing before, especially with lung sounds.
