I'm not a big K550 fan, and nothing will isolate as well as the QC15 (you will always be giving up isolation to go away from the QC15). Their isolation is average, their imaging is average, they're somewhat mid-treble forward, fit is somewhat temperamental, they're kind of ho-hum in my opinion, but you don't want bassy, you have very picky aesthetic requirements, and there's not a lot of options left.
