I just got my set I had ordered at the drag races in June. They mold onsite and its what the drivers use in the nitro cars . Bluetooth speakers as well.
So far I really like them but I haven't been to the range with them yet. I bought them primarily to use on my zero turn as it's just stupid loud.
I continue to use a pair of over the ear muffs as well just because it knocks the dbs even more.
They were spendy @ $200 but I'm already half deaf and it was worth it for me.
Bonus being bluetooth I use them when wife is watching something on TV and I'm in other room listening to music. I'll likely use them during football season as well.
Other bonus since they're a precise fit is the comfort - I've had them in for 3+ hours a couple times & you don't even know they're in there.
