No recommendations on witch ones work and any to stay away from
Having owned a set of Walker's Game Ear muffs, you cannot beat the Howard Leights for the money. I like them better than the WGE and at a third of the price.
The biggest thing the ensure is that you're getting actual hearing PROTECTION and not just amplification. There are a lot of muffs that provide amplification only, and sometimes the package is not clearly marked.
