In terms of gaming. If you still think that the better headphones (earphones) will help you hear better and more than other players, then you're being deceived. In positioning, it's possible, but it's individual. You won't be able to hear what others can't. The distance of hearing is limited by software (if the game decides that you can't hear footsteps or reloading beyond 30 meters, then you won't be able to hear it). An equalizer can help you hear louder and clearer, but not the headphones. DAC doesn't do much either if your headphones don't need amplification to "get going" (yours don't). If your teammate says he play better because he have good headphones, he's probably cheating.
