Adult + Pediatric Diaphragm Replacement - Fits Classic III (3) and Cardiology IV Stethoscopes + 2 Extra Ear Pieces, Compatible with Littmann and Other Stethoscope

These fit perfectly on my littmann 3m stethoscope and they worked great!

It is a good and less expensive than the name brand replacement. If you are OK with a blank diaphragm, you wont notice the difference. Also, the company was really responsive. These diaphragms didn't come with the initial order, so they resent the whole order again. It was so smooth and easy that I will definitely order from them again when it is time to replace parts.

Good

Only partly worked as replacement parts for my stethoscope

Sticks to my littman cardiology IV better than the diaphragm it originally came with. Sound quality is equal. Ear buds are not great though, lower quality- not as soft/malleable. (I didn't purchase the set for the ear buds)

Lasted 6 months with intermittent use. Worked for a bit but lacking in the longevity department. Cracking on side and diaphragm: things that did not occur after 2.5 years of using an OEM diaphragm.

This fits a Littman Cardiology II. Initially I thought it looked too small, but it takes stretching the ring around the stethoscope to fit. The fit is snug, as is necessary for the diaphragm to work properly, and it does. I don't know how long it will last and will update with any new information.

The package came quickly in the mail. The diaphragm replacement was much easier to install than I thought it would be. Before investing in a new stethoscope, you can save your old one if the diaphragm seal is the only problem. Or don't, you might want a new stethoscope, anyway.
