DLO Portable Speakers for iPhone let you enjoy your music and videos in stereo sound without any threat of TDMA interference. $50.00 (via ThisNext Blog)

Most speaker systems aren't compatible with the iPhone because they do not block out the much dreaded GSM buzz. Fortunately, these speakers by DLO are properly shielded against the buzz. One aspect of the design I like is how the speakers are detached from the main docking unit. Most iPod speaker sets do not allow you to move their speakers for proper sound distribution.

I just ordered these. Now I'll be able to play my iPod outdoors (because you can power it with batteries in addition to the power cord) and then easily pack it away into a little, compact egg shape. (via DLO)
