I am so confused and the people at two different music places could not explain properly. All I want is a great pair of over the ear headphones so I can use it with my android phone, laptop, and desktop for home use only.  I don't do any mixing, or dj and I don't care how big or beautiful, or small and beautiful. Price budget up to $350 max.  I hate beats, sony, etc. And wanted to go a different high end route like akg, or sennheiser.    akg k550, sounded great...
