V-Moda XS: bass heavy, "V" shaped sound with lower mids a bit recessed, doesn't have the sparkle in the highs like the MDR-1A, more grain in the treble, if coming from beats then these will sound better.And the others? In particular the momentum and the V-Modas.
Momentum over-ear: slightly bass heavy, "U" shaped sound, a little more extended highs with some sparkle like the MDR-1A
Momentum on-ear: very close to the over-ear but bass is better controlled and the alcantara pads are more comfortable to me over the leather ones on the over-ear.
Might want to go with PM since we are getting off topic
