MSA Sordin Supreme Pro-X v. Pro Ears Pro 300
Drawbacks of the Sordin: Low (perhaps misleading) NRR rating of 18db (although this article addresses this concern here), batteries are not easily removed or placed in the compartment, the sound is limited to 82 dB(A) equivalent sound level but can not be increased.
For the Pro Ears: Good NRR rating of 26, amplifies sound sub 70db 8 times, 300 hour battery life, three year warranty, Made in the USA.
Drawbacks of the Pro Ears: Requires four not so easy to find N sized batteries (CR123 versions are available but even those batteries still are not necessarily available everywhere), each ear has independent controls that turn in opposite directions (so you may actually leave on side on thinking it is off), not waterproof.
