Doesn't it seem like everyone is a DJ these days? Oh wait, Portlandia already made this joke. And they had a whole sketch comedy show in which to do it, whereas we only have a few measly sentences. We'll never win.
Why do pro headphones have two speakers, when DJs only ever seem to listen to one at a time? You know what we're talking about? Where they bend their neck down to hold the headphone while they spin? Seriously, though, why hasn't any audio engineer overcome this problem yet?
