Is it worth spending $90 for headphones?

I just got studio type BOSE headphones from my mom. I think they were like 50 bucks. OMG, Im in love with music all over again. I cant wait till I smoke with these on

I have the CX300 version of those headphones; they slip out really easily. And the only way to get ANY bass is to have a PERFECT fit (suction). When they work, they sound amazing; too bad a slight nudge can pull 'em out.
