I most play fps games but I also listen to music and I watch moives aswell. Which one should I get?
The Audio Technica has better imaging and treble but lacks any form of low end. If ultra competative gaming is what your after I say go ATH, but the 700's not the 9 series. But for enjoying music, movies and games the Sennheiser would be my pick and it will be no slouch in the gaming department.
Senns. Because, Heiser.
