Few people realize their CDs contain hidden layers of rich musical detail. That's because most of us listen to music through cheap headphones. Strapping low-quality headphones on your head is a lot like trying to listen to a live band while wearing earplugs--you can identify the tune, but the details of the instruments and vocals become cloudy and muffled.
But a good pair of headphones will strip away that cloudiness and reveal details that might shock you. The most reasonably priced headphones on the market that can accomplish this task are the $700 RS1 headphones by Grado Labs Inc. (www.gradolabs.com).
