... rx700/rx900 are bass heavy and not really neutral which is required for gaming... i have checked siberia vs higher end headphones and i think it has a good enough sound if you are getting it for 4-5k... the sound quality is should be better than the rx counterparts... neutral with more detail and bigger soundstage... the jvc headphones would have better bass but that is all i think they should be better at... but v2 dies out... i mean it won't break but the driver itself dieswell syberia is more comfortable than rx 700, but its made particularly for gaming purpose, gives u much more clarity and better sound of small differences in games like footsteps and other things, and if u bundle it with usb sound card it will give u good surrounding effect.......and yes its not much durable. as the same problem with razor products........
i quoted hammer of thor here as i am using His usb syberia sound card (got via max007, U know )
