XB500s aren't produced anymore and now cost upwards of $70 or more to get a unit. Not worth it at that price.

Monster N-Pulse... I think they look good and produce a healthy amount of bass with a good overall warm sound. You can get them cheap from eBay (bought mine like at $100 but have seen auctions end anywhere from 65 to 95... they are new also, so no fakes yet as far as I'm aware of! ;)).
Could recommend others but they are not all that good looking! ;)
The clarity is terrible and the cord is not only not detachable, but it is double-sided as well. At least the cable is flat do it doesn't tangle often, but still. But they offer a sound signature that will blow you away if you're looking for nothing but gobs of bass.
The XB500 basically sound like a parody of the Beats sound signature, taken to full extremes.
I still fully recommend the ATH-PRO700mk2, but be aware that the pads need a bit of stuffing to feel good on the noggin.
Unlike Beats, the bass doesn't overpower everything else. Beats are a very poor example of how to voice a fun, bassy headphone. These headphones should be quite a bit bassier than your Beats, and yet have far less of a muffled sound. The bass still has the potential to cover up some detail, but this just happens with bassy headphones in general, because frequency response is all relative; in order for something to be added in one area, something must be taken away elsewhere.
