If the tiny speaker on your iPhone isn't cutting it, just dock it into this cool new Yamaha Portable iPhone Speaker. This hardcore octagon-shaped speaker dock for the iPhone and iPod delivers extremely accurate low bass and crystal clear highs through its 4" woofer and 1-3/8” tweeter. It's highly portable (AC and Battery), has a rugged design so you can take your tunes anywhere and includes a sturdy metal handle and remote control. Great for outdoor parties, amping up an alarm clock app or actually being able to hear in the shower.
