## Questions & Answers

**Q: Where are these manufactured?**
A: I’m pretty sure these are made in the plant down the street from me. Check their website. Otto Engineering of Carpentersville Illinois.

**Q: Can volume be adjusted for each ear**
A: Yes, but there are only TWO settings... and it’s not as good on sound canceling / reduction when firing weapons as a standard peltor or similar ear pro device.

**Q: Is it possible to replace the rechargable batteries as they age, or you have to buy another set?  (and if not replaceable, approx. how many charges?)**
A: Not replaceable. You would have to buy another set

**Q: Anyone use these for loud music, or concerts?**
A: I’ve use these for figure eight derbies and they were great but they’re not a license Dealer and they will not honor the one-year warranty
