I’ve had a set for just over a year, now.
What I like:
1 - I prefer in ear protection, because my ears hurt when I wear over ear protection with safety glasses.
2 - The microphone helps to have a normal volume conversation with those around you and hear range commands/alerts.
3 - I work in construction and appreciate being able to answer calls without having to take everything off to talk and listen to something if I’ve got a mindless task moment.
4 - Good protection for 9mm/40sw handguns and 22lr.
What I don’t:
1 - After 5+ hours, my ear holes get cranky. The sizes of the foam are just a little too small or too big.
2 - I didn’t find them sufficient for center fired rifle rounds or comped unlimited class handguns. When I’m shooting rifles, I switch to my custom molded ear plugs and peltor muffs. The Xcore are 29 snr, which appears to work out to a 25/26 nrr. Normal foam earplugs give you way more noise reduction.
3 - The microphone isn’t the best. In noisy/windy environments, it can be challenging to make out a conversatIon.
YMMV
