Can anyone recommend a repairer of electronic ear defenders. I have been sold a pair of used Peltor Sport-tac ear defenders and they are duff. The seller, who at this stage shall remain nameless, is refusing to answer any correspondence, claiming they were alright when he sent them. I have a feeling that the left speaker is not working, but the volume is so low that I am unable to hear speech when I am wearing them. They could turn out to be the most expensive 'Passive' ear defenders that I have ever owned. I am seeing prices like £60 for overhaul and repair, and at that price, I may as well scrap them. I can buy new at £120. At my age I am reluctant to spend £300 on top of range defenders as I do not know how many more years I can carry on shooting. The person that I am dealing with is a 22 years old top shooter who is sponsored by Swatcom, which is why he is selling off his old defenders. He must be poor though, if he needs the money that much !
