That's what I'm replacing.. they just fell apart after like five months, plus even the biggest size bud wouldn't fit into my ear right and it always fell out.. I have some DJ style headphones that I'm using now, I actually found a way to sleep on them in class but I would really like some ones that I can just put in my pocket.
Oh but this system I got on this computer def. has highs, the woofer lacks quite a lot though, it's actually kinda pathetic the box they put this thing in makes more noise when you turn it up pumping out air from like an inch slot than it does producing the lows.
