Common questions
Which stethoscopes does this kit fit?
The Littmann Classic III, Cardiology III, and Cardiology IV. Rotate your chestpiece and read the etched model name to confirm before ordering.
What is included?
A diaphragm, a bell cover, and one set of ear tips in your chosen color. The chestpiece and tubing are not included; this kit refreshes the stethoscope you already own.
Will it change how my stethoscope sounds?
No. A fresh diaphragm restores the seal a worn one loses; the acoustics work exactly as designed once the parts are seated.
How hard is the install?
Tool-free, a few minutes: the old diaphragm lifts out of its rim, the new one seats in place, and the ear tips snap on.
Are these genuine Littmann parts?
No. These are independent aftermarket parts made to fit the models named above; MotivatEM is not affiliated with 3M or Littmann.

Great product at a nice price. I needed the stethescope cover and it fit so well and snug. I am not sure but it almost feels like I hear better than with the original. Very satisfied!
Fits my cardiology stethoscope perfect and the ear pieces are plush. Also logo sets my steth aside from others. Super easy to install. Quality is great. Sound quality is exactly like the original. Overall functions like expected and the value is spot on. Highly reccomend

As advertised. Easy to fit and works well
Fit perfect
Excellent product
Muy económico y de buque a calidad
First my cardiology litman stethoscope perfectly!I don’t have to buy a new stethoscope! Yay!
Haven’t tried the ear replacement pieces but the diaphragm pieces fit well on my cardiology IV diaphragm. Easy to apply, seems to stay in place so far.
Just what I needed.
Needed ear tip replacement and the package comes with several options at a good price
Fits well. Nice texture and color. Diaphragm replaced and first auscultated heart today sounded crystal clear!
Works as described
You need to know product kind make sure match. Extra parts great thank you
worked great for what they were needed for
Replacement parts fit well and works wonderfully!!
Great fit and quality but due to my job I go through these like candy. Prefect fit !
I normally buy the brand name diaphragm replacement for my Littman. This was cheap enough that I purchased this at the same time as buying a new Littman diaphragm. Initially, it was harder to put on the stethoscope, but now I am a big fan because it does not come off when I pull my stethoscope out of my bag. In the future, this is my 1st choice, not a back-up option. The white also looks clean and fresh. I have not used the ear pieces yet.
Better than original. Work great!
I love my new pieces to my stethoscope. It gives it a pop of color and it fits perfectly
Absolute perfect match!!
Excelente precio por el producto, cumple con su objetivo
Great sound. Fits like a glove.
