Well the bassiness comes from the lower depths, and isn't invasive like strong midbass can be. It's just 'there', rumbling in the background.
New toy syndrome out of the way, I can say there are a few problem areas, mainly a pretty strong peak at 4.5-5khz, which is fatiguing if music hits that range constantly. The mids are also a bit recessed than what I've been accustomed to lately, meaning it wouldn't be my first choice for an all rounder. It is definitely going to be my movie and fun gaming headphone though.
I guess the X2's generally good at EVERYTHING sound has spoiled me.
Anyways, I switched back to the 1540 Alcantara pads to run some sweeps, and keepn them on for a day. It really does retain pretty much everything of the stock pad's sound, including the bass, though it's a little faster down low., and consequently just a hair brighter in tone. I'd say if the eggshell pads are a nightmare to you, the 1540 pads may be worth visiting. I feel like the stock pads are just a touch more fluid, and deeper sounding, so I prefer their sound. Also, I'm not sure I like female vocals with the 1540 pads. It sounds sizzly.
edit: Wow, the DNA for that cheap? Not bad. I mean, I would still rather get the Creative Aurvana Live for that price, but not bad.
