Hi Steve, Thanks for the comments! I take it that you have'nt personally used the "SUPERSOUND" yourself, is this correct? Anyway curiosity got the better of me, and I ordered the "Koss" unit today so I can see for myself. The cheapest I could get one in Albany was $60 Tax Ex at West Coast Hi-Fi.[Tandy] Dick smiths was about $15 Tax Ex dearer. I have a "SUPERSOUND" on my upgraded "SD 2000" so I will be able to compare them. One thing about the "Supersound" is it's direct wired, so you don't have to worry about batteries. It's strange when you pay so much for a detector you then have to buy all these accessories to get the best out of it! Seems it would be so much easier and simpler if they already had the necessary extras built in. By the way another set of earphones that might interest you guys is some that John Dyer over east at Toronto N.S.W. sells. Don't know how expensive they are now. Mine cost $60 couple of years ago. They are very small, cool and light and very very powerfull. They actually are V shaped and fit up under you chin. They work extreamly well with the "SUPERSOUND" Signal Enhancer and you only need the volume turned up slightly. John Dyers Ph No.....0249596188. Sorry I can't tell what the phones are called[ Strangely there's nothing written on them] Thanks again to you and Greg for the Info. Best wishes, Marsh.
