Dragging party music to the park or patio doesn’t have to involve so much actual dragging. More party, more easy! You’ve got a gazillion songs on your phone already. And little, portable Bluetooth speakers are getting so cheap. Now, for $100, you can blast your jams to high heaven—or, at least, a 10-meter radius—without any hassles.

Testing Methodology

Gizmodo tested four Bluetooth speakers, listed at less than $100, to find out which one packs the perfect combination of portability, sound quality, and volume. Basically, these speakers should deliver easy wireless audio to go. So their mobility matters.

They tested each speaker to make sure they’d play nicely with an iPhone, a MacBook, and a Samsung Galaxy Nexus. Bonus points for any additional features.
