Classic III Grey

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.

Better than trying to get them from the dealer

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.

Very soft and nice easy to add on

Product is absolutely terrible. It barely fits over the face of the stethoscope. The rubber doesn’t grip well. Edges of the diaphragm are exposed and does not transmit audible sound very well.

As described

Replaced because my broke after 25 years. Fit perfect for a generic brand on my Littman.

Las membranas no están mal pero se deterioran muy rápido y se dañan.

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 🫶🏽
