Hello Irish, There is nothing wrong with you Koss Headphones. They are tuned for your Explorer. A fair while ago I E-Mailed the chap who owns and makes Ratphones, about supplying me with a pair in Australia, His advice was, That there was nothing wrong with the Koss, only that they were not as robust as the Ratphones. I have been using mine for 4 yrs and have not had any problems with them. They have been worn for 3-4 days a week and 6-8 hours a day, no problems. Also Koss have a life time Guarantee. I Have high range hearing loss, I don't hear the phone ring if I am further than 10' from it, but I have no problems using the Explorer and the Koss headphones. I don't dispute that you would hear things differently with other headphone, BUT, when it comes down to it , I don't think you will find any more. I know this will probably cause an uproar, but that's what I have discovered, That you will not have any more in you bag at the end of the day. You can alter the sounds by the controls on your detector to suit your hearing any way. In the end, It's up to you, but why wast money, after all, Isn't that what your trying to find. HH
