Near the top of my “how come I did not think of that” list is a device that keeps earbuds from getting tangled. Stuff your mp3 player in your pocket and it could take several minutes to untwine the buds.
A local Houston inventor beat me (and everyone else) to market with the Earbud Yo-Yo.
It is a square Yo-Yo minus the string. Wind your earbud cable around the Yo-Yo to keep it from getting tangled. The concept is simple enough and is really along the lines of winding your earbuds around your mp3 player.
The difference here is that the design of the device appears to prevent the cord from loosening up and becoming tangled, as cords wrapped around an mp3 player are apt to do.
For fashionistas the Earbud Yo-Yo comes in several colors and “skins” to match your clothing, attitude or your music.
