I don't claim to be some crazy audiophile or anything, but my beats earpuds plugged into my 8x make the best sounding music I've heard coming from a portable device. To my ears I hear clear, consise music with punchy bass, and no shortage of volume without distorion- this after years of listening to music on buses on various walkmans/mp3 players, and phones with the volume all the way up to just even be heard, and the music badly distorted for the effort.
Maybe Boses or Klipsch's are better, bu I have no complaints.
