Apple’s EarPods aren’t too bad for gaming, what with their in-line microphone capabilities, but they’re really not the best for long game sessions; honestly, they just end up hurting the inside of my ears.
And as far as gaming mice are concerned, you really do need one with a second button at the very least.
While you’re at it, of course, you want your gaming peripherals to match your Apple style. Razer’s Taipan ambidextrous gaming mouse and matching Kraken-pro headset are exactly that – quality peripherals that make your gaming life easier and your style just that much more put together.
