It wasn’t all too long ago that we featured the Boom by Ultimate Ears (you should be thinking of the portable, stylish speaker that packs huge sound just so we’re clear). Today we’re bringing you the brand's smaller, equally impressive addition that just hit the market, the Ultimate Ears Mini Boom. A compact, more personal version of its counterpart, this Bluetooth speaker delivers astounding audio that you can take with you on all your adventures. The Mini Boom offers up to 10 hours of battery life -- and by simply pressing a button or downloading the mobile app, you can connect two speakers for a stereo-like experience that stretches way further. Purchase it HERE in any of the five available colors, but just don’t be startled when such loud music is coming from such a small device.
