Compatible Replacement Tube by CardioTubes fits Littmann(r) MasterCardiologyI(r) and Littmann(r) Cardiology III(r) Stethoscopes - 7mm Binaurals Sky Blue TUBING

Purchased this as replacement tubing for Littmann Cardio 3 and found the quality lacking. I didn't realize that the entire binaural assembly is attached to the tubing so the only original Littmann parts that were going to remain were my bell/diaphragm. The tension on their aural assembly is less than my original and doesn't make a good seal in my ears. The earpieces are fine, but because of the way they attach, you have to use theirs and not the Littmann ones. Tubing felt lightweight/cheap. Fine for the price but this was not the diagnostic quality I was looking for. Returned it and spent more elsewhere to get a genuine Littman binaural assembly.

I was hoping to replace my tubing to my very nice bell on the stethoscope. This quality was not even close to what I was looking for.

Seemed cheap. I returned it

The tube is thin and the transmission of sound is no where as good as one would expect for the price paid. Maybe if the tubing was a little thicker the sound quality would improve. Very, Very disappointed !

This replacement tubing did not work for me at all, heart sounds were muffled or not audible at all. Returned.

Perfect replacement for my Cardiology III stethoscope! Easy to swap out and it looks brand new again!

See headline. Works great, fits perfect. Perfect 5/7 score, would buy again.

Fits my Littmann Cardiology III stethoscope perfectly. Easy to replace; check for a YouTube video if having any trouble. Sound quality is just like the original.
