As a USPSA competitor, I desired something different that a standard over-the-ear muff. A standard Level 1 match can take up to 5 hours, and a level 2 match may take 8 hours if it’s a one-day match. Muffs get hot, sweaty, and uncomfortable after a couple of hours to me. The Ghost Stryke ear buds completely solved this for me! I’ve used them almost every weekend for almost a year, for 2 to 8 hours at a stretch. Always comfortable, always perfect. As an RO (Range Officer) for USPSA, I have to be able to communicate with another RO between shooters to score the last competitor’s run. There’s no need to remove an ear bud to do this, while protecting my hearing as a shot is heard, these actually magnify sounds as long as they are under the safety threshold. I’m happy as a clam with the product and the Customer Service! I recently had to send my set in for refurb (I bet competitive shooters are harder on their equipment than other folks) – I had them back within 2 weeks! Wow! … Obviously, I can’t say enough about the product or the company. A+++++ in my book. If you’re looking for a generic-fit ear bud, you won’t find one better! As I get better/more accomplished in shooting USPSA, I may look at some custom molded units, but until then, the Ghost Stryke buds are perfect for me! Thanks SportEar!!!
