## 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.
