The Sennheiser 598 is the new the ruler of the sub-$300 roost.    If you're looking for a headphone with an expansive sound stage that is at once both intimate and expansive...   If you can't shell out for a Hi-Fi set of cans like the HD600/650 and the necessary amp to drive them well....   If you're looking for a versatile headphone that bring music to life but doesn't punish your ears with poor source material...   If you're looking for a headphone that you can comfortably wear all day long....   If you're like me, and use your computer...
