I will mostly use the headphones for gaming and movies, so I want good bass, but I will also start getting into listening to music more, so I want them to sound good there too. My thoughts about the X2: They weigh almost 400 grams, isnt that a bit heavy? Will I get tired after several hour use? Will they sound bad without a DAC? (My motherboard is very old and has quite a bit of static noise, if I were to plug them directly into the mb with no DAC, would they sound bad?) My thoughts about the AD500X: I heard they have amazing soundstage, but terrible bass. Would the bass boost on the E10K be enough to counter it? Does a bass boost ruin the sound in any way? If not, are there any other headphones/DACs which would fit my use better? (Nothing too expensive) Im really new to audio gear and headphones, so please explain in simple terms, thanks!
