HyperX or Razer?

I'd say corsair has grown far with their RGB. alot of games have this cool integration(like metro for example) where your mouse adjust to the game situation. this works for a suprising amount of games. i see razer as overpriced but not bad quality.

HyperX is good. If you really care about sound you could get brands that are respected by audiophiles like sennheiser
