Custom molded earplugs? Chamelion ears?
Curious if anyone uses these - I am spending more time at the range and in search for something more comfortable - something that stops impulse noise while allowing you to hear conversations would be a big bonus. I have used Sonic Defenders and like the way they limit impulses but still allow you to hear. I have also used instamold plugs - but they are still not perfect (could be more comfortable and I can not hear range commands with them in).
I understand electric muffs would probably work better, but I prefer plugs (around rifles more than pistols).
Specifically curious about chameleon ear's with their sonic valve.
