Bed can blow out teen eardrums

If you've got teenagers in your house, you've got loud music. Lots of it. But be aware, it could be worse: They could have a bed that plays music too.

The "Tune-In Bed" from PBteen essentially turns an entire headboard into a sound system with two 4-inch stereo speakers and a control panel for connections to an iPod or MP3 player. (Maybe there's a way for parents to hack the volume levels.)

This "biggest iPod dock in the world," as Red Ferret calls it, doesn't come cheap--it's $700. But that's a lot less than a bed with a TV.
