If you own an iPhone you might have encountered this problem before: interference bubbling up while playing music on your speakers.

Here's a gadget you might be interested in so that you don't have to endure the ear-piercing (or at the least, annoying) sound ever again when playing music from your iPhone: portable speakers shielded from interference.

The DLO Portable Speakers are available for US$ 50. It's powered by AAA batteries or by an AC adapter. The two speakers snap together, and has a recessed area for storing your cord for more portability.

Another useful feature is that it can act as a speaker phone during a call when connected to the iPhone. You can also connect the speakers to any other device that's compatible with the audio plug. If you're the type who uses your mobile phone often while playing music on your speakers, this feature would come in handy.
