You'd be disappointed to find out the Sordin Supreme Pro X muffs have just a rinky dink 19 to 24 NRR, while the Pro Ears Mag Gold are NRR33 which is as high as hearing protection goes. I bought my Pro Ears and after 4 years and 11 months one of the cups was cutting out. Sent them back and received new electronics in both cups so they're actually better than new, as the newer version turns off after 4 hours
You best re-read what the different NR rankings actually mean. The Sordins are the equal to the Pro Ears and them some. The Sordins have much better rain/water protection as well. I wear glasses and the optional gel cups seal aroind the frames really well.
To the OP if you don't want/need the electronic feature for around $30 a set of Peltors with a rating of 33 are as good as you can get for protection alone. I went with the Sordins because I do a lot of SOing and instruction in IDPA and need to hear the shooters/students.
