Afraid so Corky, but you will still be a fair bit better off than most site chippies I have encountered who have nothing at all, which is not good for them and a pain for their clients if they are working somewhere that is occupied. Talking of being not good for them, I continue to be amazed by the number of tradesmen who work with very noisy machinery but have no ear defenders. I have spare pairs and insist they use them. They seem oblivious to the fact that hearing damage is cumulative and once lost can't be regained,
