Here’s a cool set of DIY headphones that allow you to control your iPhone volume and whatnot through its motion-sensing circuitry. I find that this is a really awesome headphones for headbanging bloggers like me who are too lazy to use my hands as they are tied up with my mouse most of the day.
The ’tiltphones’ are a motion-sensitive iPod remote control. Electronics built
into some over-ear headphones pick up what way your head is tilting and
sends commands to your iPod accordingly.
