To clarify about the bass: It's fantastic, but also accurate. Meaning, as far as I can tell the bass isn't boosted like in many cheap earphones or the Beats I've heard. This is important to me because I mostly listen to classical. I want to be able to hear the bass notes accurately and powerfully, but they should never be stronger than what one would hear in a concert hall, i.e. what the composer intended. The right amount, in its place. The entire reason I got into high quality cans is because the cheap ones I had bought were basically inserting bass where it shouldn't be. If I wanted to rock out, I guess that's ok (although tiresome even then), but in a Bach concerto it's really unwelcome. So with these it's spot on. If I want to rock out (think Rush, Zeppelin, or even Bjork), it's there. If I want to listen to some boomy organ music, it's there. Glorious, in fact. When the organist starts stomping on the bass pedals at the close of the Saint-Saens organ symphony, for example, the sub-bass is sublime. But if we're talking a double bass or a cello in a symphony, and the bass notes are part of a balanced pallet, I'll hear it accuratelyin its proper measure. As for Beats, I once borrowed a co-worker's pair, which I believe cost significantly more than the 770s. That POS was ok for pop, but when I put on orchestral music, the whole bottom to mid- range basically was a muddy wall of sound. With the 770s, I heard detail and clarity. No mud. No wall. Just gorgeous sound. There probably are better open-backed headphones for the price, but for closed, these are fabulous.
