I feel it should be down to the individual, wether or not they wear ear plugs, I have had in the past some really big and MEGA expensive surgical operations on my hearing system, but I know that ear surgeons make the statement "The smallest thing to go in your ear should be your ELBOW" enough said, would you put cotton wool in your M/R gearbox! I always use my own set of ANR cans, they work for me without any plugs, and as for the expense, well I only have one set of ears, so as with my eyes I try to use the best I can!
