I'd personally hold off on buying anything until a good number of reviews post on the Apple Store...you will see Powerbeats2 had BAD reviews for the same reasons I posted. Let others test them out for you.
Here's the link I was talking about. Without the rubber stabilizing piece they look just like the apple headphones. Sweat resistance and cheap. I haven't used them personally but my co worker says they work great in the gym for him. I'm thinking about giving them a shot soon.
