bought these in haste for $55 after losing my perfectly adequate koss porta-pros (which i think cost me whole $25 when the aussie dollar had value). I assumed that $100 RRP from a reputable brand must be a decent thing. so disappointed.  If these were $20 perhaps i wouldn't be quite so harsh, but...
 
If you like to hear your music through a woolen balaclava, these are for you. no amount of EQ can fix them. Boosting upper mids or highs to compensate for the "everyone wants Beats" low skew just shows up how cheap and nasty these 40mm drivers must be. Cut at the other end and it all falls apart.  I'd hate to think what the XB (extra bass) series sounds like.  Since they can't really give good bass, they drown you in boomy, woofy low mids, obliterating any mid-range clarity. It's like you've been dumped in the surf and can't get that swill out of your sinuses.
 
If you wear glasses (as i do) the pressure of the cans will leave you with bruising after a moderate session.
 
I trusted the majority positive views online but i regret the purchase.  Had they been full price i would have returned them.
