Adult + Pediatric Stethoscope Diaphragm with Rim assemblies. Fits Cardiology III (3) + 2 Extra Ear Pieces. Compatible with Littmann and Other Stethoscopes

Sound is now great, these fit my littman nicely

Thought I was getting real replacement parts.

The rubber rim fits really well but it was a little bit hard to attach. Nonetheless, this is still a good buy because I only need the large rubber rim and the branded set is expensive which I will not use most of it anyway.

Mediocre sound quality, rubber seal cracked within months.Spend the real money on the brand replacement - don't waste your money here.

Recomiendo Al 100%

Earpieces are OK, but rims and diaphragms are junk. Doesn't fit, and sits much higher from the surface of the stethoscope than it should, and crimps the diaphragm so the "tunable" part of the original diaphragm cannot "float" as it should. The replacement diaphragms are much thicker and the rubber edges much more stiff so will not produce sound anything like the original. Spend $10 more and buy the genuine Littman version. There is no comparison.

I was able to repair my cardiology ll stethoscope using this and it was a perfect fit.

Product worked well.
