Finally you no longer have to look like a fool yelling into the Nintendo DS, Datel has released Headset for DS, perfect for when you play your mates in Metroid, or even something as simple at Brain Training or Nintendogs.

The headset will work with both the DS Fat and DS Lite, and can be ordered from the Datel website located here. It costs $15US (20AU), its pretty cheap. I would expect to see it in Australian stores soon too.
