The K812 really excels in the bass department — in that it is very flat for a headphone — and without mid-bass emphasis that I hear in numerous other headphones. Unlike bass-heavy studio headphones, such as the Sony MDR-7520, the K812 bottom end is clean, tight and fast with the energy of a really good speaker. It is part of the reason you can hear so clearly into the midrange and treble. No diverting bass boominess to mask the subtle, upper-frequency sounds.
