Classic 3, Cardiology 3 & Cardiology 4 Accessories Kit for Littmann Stethoscope Replacement Parts & Littmann Stethoscope Parts - Fits Classic III, Cardiology III & IV - Black

I lost the diaphragm on my cardiology iv, it always had a loose fit. This fits much tighter than the original. It is a little hard to put on and I accidentally bent the diaphragm plastic a bit but it sounds fine and there is no chance of it coming loose on its own. Ear parts are comfortable also, I would buy this again.

The fit was a little tight going over the bells, but worked well and works as I would expect. I would buy again.

It's funny how over time I've replaced the tubing and diaphragm, only thing that is OEM is the metal part of the head. Purchased in December 2023, only used the diaphragm retaining ring. It fit my Littman Cardiology IV perfectly fine. and worked perfectly great for almost two years. It saved many lives. Now in October 2025, it has gotten very loose, like could easily catch and fall off on it's own. Summary, works great for 2 years, but still cheaper than buying OEM.

Better than trying to get them from the dealer

I spent 36 dollars on this item. And in less than 2 years, the diaphragm cover cracked and would not stay on my stethoscope. After reattaching it a few times it came off and was lost. Now I have to buy another one! This time it will be a Littman!

The first time I ordered this it was lost and never came. I did get a refund right away which was good. I was upset but thought, it happens. I reordered it and I am glad I did. I see reviews about how "it's hard to get on" I can say with over 25 years as a Medic this was very easy to put on my Cardiology IV. I even replaced my ear pieces it came with. So with that said, I am happy I reordered it and I will again in the future as I have 3 stethoscopes.

Very soft and nice easy to add on

The ear piece fell off the stethoscope after a few weeks.

Muy buena opción para reponer las membranas y artículos que se pierden en los estetoscopios Littman, perfecto para clase III

This product is an utter waste of money. Size mentioned is wrong and does not fit my Cardiology-IV stethoscope. Build quality is very poor with a substandard finish and would have looked absolute shabby on my pristine Cardiology-IV steth had it fitted. Moreover the item is NON-RETURNABLE. What a farce and terrible way to cheat customers. It is disgusting and shameful that such sellers are even allowed on Amazon platform.

Does not come upto Littman quality. Pooe design & quality

buen material, lo compré para mi littman cardiology 3 y encaja perfectamente las dos membranas

Excelentes repuestos, económicos y de calidad genial. Recomendados 🫶🏽
