dunno if the op even gives a **** about this thread anymore, but ive posted about my thinksound ts01's before and i love them. got em for about 45 bucks and the bass is pretty serious, i doubt even beats earbuds could deliver more. and whats great is the mids and highs sound great as well. dunno about beats earbuds but i know their over ear's didn't deliver on the mids well. vocals don't always sound 100% accurate but its a set of earbuds, they gotta compromise somewhere, and as they've broken in they sound much better.
theres my little review. i would go with these headphones cause they are a hell of a lot cheaper and they have the bass you want without sacrificing overall audio quality.
