Although a popular whipping boy amongst bandwagon of beats haters, Beats Pro, Studio 2.0 & mixr's for that matter all easily hold their own and IMO are very decent cans indeedy.
As for nice bass slam - my old Detox Pro's still cut the mustard and when EQ'd with my Fiio E17 - it's a hefty bass slam to the face for sure.
...you could say, my about to be owner expectations of this particular can is sky high to experience killer subsonic bass lows...
Folks who hate on Beats especially the Pro's while holding plastic pieces of **** are just outing themselves as haters.
Switch the pads and slam these 3 first to find your footing.
That 55mm sexy as **** driver is gonna make everything alright (change the nasty ass pads)
