I don't consider myself an audiophile just yet but I'm getting there I was going to buy the Sony but right before I did, my dad said "Wait, I have a pair of old headphones you can use." They were the Bose QC3 and they now belong to me. I've had them for a few months now and they've been good but the battery is annoying, as is the noise cancelling because I can't hear anyone when they call me. I was wondering if I'll notice an improvement in sound quality with the Sony, because I found a place selling them for only $50, when they are normally around $100. Obviously they don't have a battery and aren't noise cancelling. I would use the headphones to listen to all genres of music, mostly rock. Thanks for your advice!
