We knew we were in for good things from any company called iFeelU. Their EX2 2.2-channel body-sonic earphones promise to deliver a "home theater in your ears" with real force feedback using a second pair of conduction speakers on the back. For explosions and other big booms, these things are surprisingly great, with solid feedback and definite in-ear quakage. I could see using them for mobile gaming. Two downsides: They suck balls for music. And they made my ears tickle. They're already out in Japan and Korea (like these), but they're dropping in the States soonish for only $39, so they might be worth picking up just for watching movies on the go.
