Ear plugs - which ones?
I'm looking for a set of ear plugs which can be worn underneath a headset to reduce the amount of noise but which will still allow me to hear the intercom / radio. I've tried some Peltor ear plugs but they are too effective (can't hear the radio / intercomm well enough even at full blast).
Does anyone have any recommendations for suitable plugs? I don't mind paying for a set of custom made ones, but I'd like to be sure that they will do the job before investing.
