Product Review; "Originally introduced as a more affordable alternative to the slightly more expensive SR60 Headphones in the 90's. They may be old and out of production, but the pair (I was lucky enough to find) on EBay is in almost perfect condition and the audio purity and quality and dynamic range is beautiful. I couldn't currently find another listing online but Grado is still around, and many of their models are always being sold on EBay and the like. The 10ft long cable is a nice bonus but they do definitely scatter sound out and around you. I HIGHLY recommend any Grado Headphones - your audio will sound like professional master quality." -MadeInUSAReview
