Although the @Joker partner, not a basshead really . Joking aside, I have both and I can say that although wooduo hit very well, do not compare to the capabilities of xb90ex to go down to hell. I can use high gain and apply a bass boost in my fiio X3 at sony without introducing distortion problems antd a thunderous low sub.
Not regularly but I hear dubstep, drum & bass itself much, house and tech house (Dirtybird Players with a reputation for add hard hittting bass to his musical pieces)
As stated @HBB, although the size of the driver is not an irrefutable law, in this case the difference is evident in the Sony without any discussion.
Cheers.
Agreed. I've spent a couple dozen hours with both and directly compared them. Out of a phone with no amp or EQ at low to moderate volume, the HiSoundAudio Wooduo 2 actually hits harder. Change any of those factors and the Sony MDR-XB90EX pulls ahead and never looks back.
The Wooduo 2 is light, low profile, and sounds pretty good. If you push it with EQ, it gives up and distorts earlier than I'd like. It's also common to get driver flex with them.
Basically, get the Sony.
