I haven't heard the LP2s, but I do have the LPs (well my wife has them now). The Beats Pro, beats the LP in every way. I love base/sub bass, which the Beats Pro do very well while still maintaining great separation between the mids and highs, but the LP's bass in my opinion is really muddy and bloated (a little more like the Beats Studio to my ears). This is only my humble opinion, but you will have to hear them for yourself to see how they sound to your ears. If you do get the Pros though, make sure they are a legitimate pair, as I'm sure more than half of the ones being sold on ebay are fakes. I'm pretty sure the fakes are what helps to give the Beats a negative impression also - even to bass heads.
Edit: My comparison was based primarily listening to hip hop and rap music from an unamped source.
