Sony Ericsson has unveiled the first ever motion activated headphones. The Sony Ericsson MH907 uses the SensMe Control technology to respond without pressing any buttons. The idea is that you have the two headphones in your ears and are listening to music as you normally would.

But if you want to pause the music, you can remove one ear bud to pause it. To start listening to the music again just place it back in your ear. Is it just me or are these the Stupidest headphones ever? When I’m listening to music, my hands are usually busy. It would be very annoying to have to constantly mess with what is already safely in my ear just to do things like pause a track.

JVC’s latest addition to its NX-TV series is the 15 x 15 watt NX-TC5. The good news is that the device features an iPod dock and 4.3-inch LCD. The bad news is that video playback is limited to the built-in 1Seg digital TV tuner or WMV video stored on USB media. Which is strange. No iPod video for you.

It features a movable front-panel for getting the optimal viewing angle and a motion-activated display. Some other features are 512MB of on-board storage for photos, AM/FM tuner, and a CD player that will rip audio to MD or USB stick at 4x speeds.

This potentially devious lawn sprinkler is configured with an inline valve that has a motion sensitive trigger which goes off and sends a quick stream of water without warning whenever it sees movement in its 105 degree field of view. It comes with a stake to mount it in the ground and can connect to a standard garden hose, running off a single 9-volt battery which gives it from four to six months of water-armed sentry activity.

The supposed purpose of the motion activated sprinkler is to chase off pesky rodents and birds from the area scaring them with a sudden spray of water. It would also work well to keep unwanted wandering pets out of your yard, but my first thought with this was the fun you could have with neighborhood kids passing by.
