The Grado Labs RS1e headphones are considered the gold standard for audiophiles and mix engineers needing a stunningly realistic reference listening experience. The gorgeous cured mahogany earpieces aren't just there for the looks -- they are also an integral part of the sound of these masterfully-designed headphones. With a frequency response typically reserved for large, expensive studio monitors and drivers matched to one another within one-twentieth of a decibel, the RS1e headphones reproduce music in a fully-immersive manner.
