I have a VA 30% disability for hearing loss & severe tinnitus. Hearing aids do help, but do not protect your ears from further damage like the Walker quad muffs because of the drain port in each earpiece on hearing aids. While the hearing aids do shut down at the sound of a gunshot, enough sound is allowed through the drain ports to do further damage. I tried plugging the drains w/small pieces of foam, but that managed to crack one of the housings so had to discontinue that.
ETA: Comments apply to in-the-ear hearing aids; not sure if the behind-the-ear types have any drain/vent ports or not.)
I picked up a set of Walker Quads many ears ago, and they work fine (w/or without the hearing aids). I can control volume on each side to make up for difference in hearing acuity, and they aid greatly in directional awareness as well as amplification. As has been stated, wind does diminish quality considerable, as it does with any mike.
When the first set of Walker's finally bit the dust, I bought a set of cheaper muffs, but ya get what ya pay for.
They cancelled loud noises just fine, but were lacking in higher volume.
I then tried a set of the Walker ear buds, but unfortunately none of the various adapters supplied sealed in my ears properly so had to return them. I suspect they would be fine if they fit properly, but I went back to the original Walker Quads, if that helps.
