i have had a couple of the ones with the ear muffs built in, they will stay on but i want to hear whats going on with the tree.
I've found that the rubber ear plugs with the "stem" thing on them work good. They don't block all that much sound. The tapered foam ones are too quiet. The squared off foam ones work too if you cut them in half and wear half in each ear. That's my 2/100ths of a $.
