This is where the Nabi XD's NFC takes place. Right there in the middle of that circle. NFC can be used to sync to other NFC-compatible devices, but also sync to Fuhu's line of figurines used for its Battle Kinabis game.
The Nabi Notes headphones are the most powerful I've ever had to the pleasure of listening to. The sound is crystal clear and almost completely shields your ears from all other outside sound. Available now for $99.
