For all genre, slightly bass orientated purposes, momentum 2.0 over ears, Beyerdynamic t51 or Sony MDR-1A?
PM3 for sure. It has the advantage of being internally wired balanced so if you ever buy a portable player that has balanced output, such as AK players, the Onkyo DP-X1 to name a few, you can take advantage of the balanced output which at a minimum provides more volume. Not to mention the quality of the bass is fairly advanced beyond the 1A, which is good, but more boom and bloom with the Sony than with the oppo.
