I've used the Soundgear plugs for about 5-7 years. I seem to have misplaced them after last season's hunting was done...and I couldn't find them this year. I must say that I loved them. They worked great for hunting and I just wore muffs over them at the range. Super comfy all day and easy to hear someone talking to me while keeping my ears protected when needed. Downside: no on/off and they are small. PITA (as in arse) because easy to drop. I lost one on a bird hunt in Saskatchewan once. Was able to buy 1 from Soundgear (great customer service) btw. Get tired of fiddling with battery install each morning in the dark. Used for big game, waterfowl and upland.
So this year I decided to buy some customs. Molded to my ear, fit well etc but they hiss and after i'ved used elk, deer, waterfowl and upland, I regret to say I spent $1600 and they are no better than Soundgear. Still no on/off switch so fiddling with batteries. One upside, they have a string between the two and they are a bit larger than sound gear (like an in-ear hearing aid) so if I accidentally drop one, it's not lost.
Thinking about buying another pair of soundgear; just wish they'd add on/off switches so no fiddling with batteries and a way to put a small cord between the two of them.
