I really like my sony MDR-XB500s, I love bass and these headphones reproduce it like nothing I've ever heard before. With a EQ I would place it up there with Sennhiesers gear. Without a EQ it can sound a bit bass heavy.
BOSE are garbage, They sound very tinny and don't reproduce bass for shit. All Highs No Lows Must be Bose? My MDR-150s sound better.
