These headphones don't seem to add anything to the recording. It feels like they have absolutely no color of their own. Good recordings sound incredible good! Mids are delicious but not overly emphasized like in some phones. Bass is not weak, very strong actually, and it goes deep, but it's volume isn't too loud. I use a little EQ to give bass a boost. Highs are best I have ever heard. They are delicate, soft, not too bright but still very accurate. And they extend really well. 
I am just listening to music with these, not headphones. These are very detailed headphones, so every nuance in original recording and source comes through. The soundstage is very realistic.  
 
Build quality felt a little cheap at first but the excellent sound quality makes up for that. Headphones are very lightweight so they should be comfortable. The auto adjusting design means that the wing pads press a little to my head. I need to keep breaks after two hours of listening. 
 
These are very cheap headphones but that is only a huge plus. If you want to have quality sound and also pretty comfortable phones then pick these! If I wanted better audio quality I should prepare to spend 10x the money these cost!
