They can, but if you want to use voice chat, you need something like the Astro Gaming Mixamp (which works phenomenally). It basically allows you to use any headphone with a mic control w/ your 360. Here's a link...but keep in mind, it just adds another 140 bucks to your purchase. :) I already had the mixamp that I used with the Astro Gaming a30 headphones, so it was just a simple headphone swap for me.
