Don't Use Them As Golf Balls
Here's a twist on the conventional MP3 player that we thought was worthy of note. Taiwanese electronics manufacturer Genius in late January began shipping a line of rechargeable, amplified speakers that at the high end can play MP3 and WMA audio files right from a USB stick, or can amplify sound from an iPod, iPad, smartphone, laptop or other media player. A 1.5-inch speaker puts out two watts of sound, powered by a lithium ion battery that lasts up to eight hours and recharges in less than two. They also can connect to each other to form speaker chains. $25-45 list.
