I am an RSO at a Machine gun range and utilize Walker Earpro every day and in 3 years this is my second Gel replacements. Love these. Comfortable and safe. I have an audio gram every year and no changes. Very satisfied with the Walkers along with the gels.
I've used gel ear pads in aviation for years so I had a pretty good idea how they would feel. They did not disapoint. Instant relief, easy to install, a bit pricey though.
The jell cups are a vast improvement over the originals, however that said, most jell cups are softer and for people who need glasses there is no cut at the top to slide your glasses though.
