During IGN’s preview of Animal Crossing, they ran accross an option called Use Headphones.

The questionable option within the menu: you had the ability to turn on and off a suspicious “Use Headphones” switch. On the one hand, it could just be an option to adjust the sound equalizer so you’re not blowing out your eardrums. On the other hand, I was thinking that this could be an optional ability to separate and send the voice through optional headphones, but you don’t plug headphones into the Wii. If you want personal sound you have to plug into a sound system or directly into the television, so maybe this option sends voice through one audio channel and the in-game sound through the other? It was a feature I couldn’t test, but keep your ears peeled.

Any ideas of what this could be?
