So I need some headphones that can be used on the bus/in library - need good soundstage and low noise leakage, balanced sound.
I first though about the AT M50Xs, but the soundstage is not meant to be great.
Are the k451s any good (much of an upgrade over my px100IIs)? What about AKG K550s or Denon Dt770s, or maybe Sennheiser momentums?
I don't have an amp but am thinking of getting one. Would appreciate any recommendations. Max £300.
