Featuring a specially tuned pair of 40-millimeter dynamic drivers, the Sennheiser HD 700 offers a unique listening experience. The bass is tight and deep, the midrange is linear and clear, and the treble is detailed. Resolution is one of the strong points of the HD 700, and with it, music sounds remarkably engaging and clean. Coupled with an enormous soundstage, which presents every instrument exactly where it should be, this makes for a fun and exciting presentation.
