Ultimate Ears' smaller Bluetooth speaker, the WONDERBOOM, is currently available on Amazon for just $84.99. However, only two colors are priced at $84.99, which is the black and lilac colors. The other colors are still at the regular $99 price tag.
The UE WONDERBOOM is one of the more interesting Bluetooth speakers from the Logitech subsidiary. It's a small but somewhat fat speaker from Ultimate Ears, which still offers up 360-degree sound, as well as some great sounding audio. You can pick up the WONDERBOOM and take it to the pool, since it is waterproof like its other speakers, and it'll actually float and still play your music. It has a range of 100-feet for Bluetooth, and you can also daisy-chain multiple WONDERBOOMs together to get even better sound. Finally, the WONDERBOOM also has 10 hours of battery life, and recharges via a micro USB port. This is a great Bluetooth speaker to pick up, especially if you are looking for something small, with great sound and a small price tag.
