"The Koss ESP-950 electrostatic headphones debuted in 1990, so color me embarrassed -- I'm a little late to the party. The good news is the ESP-950 is still being made, and this 26-year-old design is more transparent and spacious sounding than some of the best headphones I've reviewed over the past few years."
