I don't really want to talk about the use of these for music.  They were once the king under $100, and still are very good for the price -- but the best low-end headphones today would give all but a few midrange headphones of a decade or two ago a run for their money -- so it's impressive how well these have held up.  But there is just better out there for under $100 now.
 
That being said, over the years I've tried many popular headphones from the major brands while gaming -- and for gaming these are still by-far the best in terms of 3D positional accuracy.  If you play games like CS:GO where audio cues are absolutely vital I cannot recommend these highly enough.  Sony really needs to produce a version of these with a mic and market to the pro gaming community -- they would be incredibly well received.
