My eight year old Sony MDR-V600 finally stopped working. I am looking for a pair of over-ear headphones to listen to my Roland RD-700NX digital piano and to music (mostly classical and rock) through my Apogee Duet.
Which headphones would be best? I've been looking at Sennheiser's 598/600/650 as well as Beyerdynamic's 770/880/990, but I am open to any headphones under $500. Any advice is appreciated.
