For those of you unaware of what binaural brainwave generation is, here's a quick synopse: brain functions operate at extremely low frequencies, below 30hz. This can be simulated in your mind by subtractive synthesis: playing a frequency of 500hz in the left ear and 505hz in the right, for example,
creates a beat pattern (or overtone, like in music, think guitar harmonics) of 5hz, which corresponds to a brainwave level in the theta state (first stage of sleep, or drowsiness). One of the practical problems with this is trying to induce sleep in bed with a set of headphones on. Tossing and turning in your sleep would be brutal on a set of wired headphones, or would knock off a set of wired phones.
Wireless earbuds, however, would be no problem. Imagine a foam earplug imbedded with wireless circuitry to hook up to a CD player or computer which generates the brainwave frequency. The player/computer also has a timer which cuts off the signal after a given time, so that it can be used to induce sleep, and will cut on at a given time, waking you up via brainwave stimulation. In essence, an alarm clock. During the day, if you need a little stimulation for creativity or alertness or whatnot, you can use your wireless earbuds to do so comfortably and still do things around the house, like clean or write or program or whatever it is you do at home. Program a siesta for yourself if you like, create naps when they are convenient for you before you fall asleep during a big project.
You could also program it to change the brainwave timing so that you could fall asleep more quickly after, say, an evening of energetic activity, as opposed to a quiet night of watching PBS.

||I tried a peice of software that did this once, and it was very loud. If these where on for 8 or more hours a day, you would probably go death. But then, maby the software was faluty.
||Faluty... but maby that would only make you go death in one ear.
||Shouldn't your earbuds produce the sounds themselves? Otherwise, if you still connect them to a stereo or computer, your idea is more about a wireless headphones solution (but with earbuds instead of headphones of course) that you can use for any type of audio. And wireless earbuds seems to exist already, at least for mobile phones.
||Anyway, I got curious about the brainwave stuff and found a link to a software generator.
