Grab the UE Wonderboom portable Bluetooth speaker in subzero blue for $49.99 through the official Best Buy eBay page or on the main site. This is one of Best Buy's deals of the day, so the price is temporary. I'd go for it if you can because the deals on this speaker have been growing fewer and fewer. This version isn't even in stock on Amazon and the colors that are available are selling for $80 or more. That's also the same price as the newer Wonderboom 2.

Sounds good

This Bluetooth speaker sends out sound in all directions with its 360-degree design. It offers 10 hours of battery life per charge and can be recharged easily using USB. The 'Boom' in capital letters within its name is no joke either, this speaker is loud, and the best part is that you can bring it just about anywhere, whether that's to the beach, to a party, on vacation, or even in the shower. Thanks to its IPX7 water resistance, it can stand a splash of water or two. It can even float when you're using it in the pool. Buy a couple of the speakers and pair them together so you can kick the party up a notch. Combining two speakers is easy to do and allows for fantastic stereo sound.
