## Questions & Answers

**Q: Can I replace the ear pieces too or no?**
A: Mine came with a variety of new rubber ear pieces. The metal in the photos is new as well, not from the donor stethoscope. The only thing to use from the old stethoscope is the bell.

**Q: Are replacement ear pieces available?**
A: My tube came with several ear pieces, and so far I'm happy with the quality (approx. 1 month of use).

**Q: Will this fit a Cardiology ii se?**
A: I'm not 100% sure, but I have some sort of Littmann Cardiology stethoscope and it fit easily. Still holding up well.

*by D***A on 13 January 2024*

I guess this the ultimate piece I was looking for replacement or DIY master cardiology stethoscope for enthusiast. Seems good, it's quite pricy as per Indian price. In this price we will get descent quality 2 to 3 stethescope in india. I wish littman precision master cardiology or IV cardiology stethescope bells are also available for order from same manufacturer. Plz keep the price bit reasonable and affordable. Littmans diaphragm and ear pieces are easily available but rest of the spares are not available for loose purchase. We are looking forward for replacement by other manufactures too.
