A couple of thoughts on my experiences with ESP.
1. Having these is a huge advantage in sporting clays. Being able to hear the traps go off, especially when you can't see them, is a big advantage over the competition. A drawback would be hearing the people talking behind you when you're in the stands, but you can always easily turn them down with a turn of your finger (the ESPs, not your squad-mates). It's also nice to hear the scorekeeper after each pair. They tend to mumble and we probably all have gotten burned once or twice stepping out of a stand and then finding out that the scorekeeper made a mistake and we never heard it.
2. To order these, you have to go to a hearing aid place to get molds made of your ears. During this process when the compound is in your ear, make sure to move your jaw around a lot, like you were yawning, and open and close your mouth as far as it will go, move your jaw left and right, and make a chewing motion. No one told me this the first time, so I held very still. When I received my first pair they fit perfectly when I first put them in but whenever I would move my jaw at all, they would always slide out and harmful sound would leak in. When I called ESP, they were super helpful and had me go back to get new molds made. They said to move my jaw and mouth constantly while the molds are being made, which I did, and my second pair was perfect and still is today 2 years later. It also didn't cost me anything to have them remade.
3 If you have a HSA health insurance account, they typically cover hearing aids, so you might be able to use that in this purchase.
4. As a professional musician and music aficionado, I was slightly disappointed in the sound quality of the Stealth ESPs. It's very thin, tinty, and treble sounding. It's nothing at all like good headphones or earbuds where music sounds full, warm, or rich. Because of this, I would probably buy the cheaper version next time. The cheaper version still has the custom molded earplugs and decibel cut.
