Let me start be addressing the "le no base XD" ... No these cans are definitely not for bass heads by any means (so they could use a bit for for those who mainly listen to things such as dubstep or really bassy rap and what not) but these headphones can definitely produce nice, sharp and clean bass!
To get a bit more bass I read in another review here that they can be EQ'd very nicely (I just haven't tried quite yet seeing as I'm very pleased)
 
The highs on these headphones are very sparkly and beautiful! Female vocals are astounding (I love to listen to Lorde on these headphones!)  The mids are also very clear and crisp. 
 
The sound stage is very wide as you would expect... Nothing much more to say on this topic.
 
Last is the comfort: I have worn these headphones for 14+ hours at a time (Long skype calls with friends while playing games and such) and they were never uncomfortable at any point during this time period... Only thing was.. I am using a rubberband for added support.. without the rubberband the headphones would it on the tips of my ears and make them sore after a few hours (which is a major flaw, even though it can be easily fixed).
 
Love these headphones! Don't plan to upgrade for a while until I get the dosh for some Audeze LCD2's (which.. will be a while)
