Those headphones are just cool. 
 -> good sound
 -> easy spreading and slicing
 -> they look awesome, don't they?
 -> you can hear to music really loud
 -> not really expensive
 
But, besides, they have three minuses:
 -> after several hours sitting and listening to music/playing games your ears really hurt,
 -> my friend was listening to music really loud and I was able to hear what is he listening to,
 -> I usually have length 3 on left side and 3 on right side. Sometimes Somics were slicing to 3 on right side and e.g. to 2 on left side. 
 
Sorry for bad english, I am learning it I hope you will be forgiving for me
