One of the best Bluetooth speakers on the market, the UE Boom Wireless Bluetooth Speaker is on sale. I reviewed this speaker late last year and have loved the speaker ever since. It's currently on sale right now for $179, which doesn't seem like a crazy good deal, but it is $20 off the normal price and does have Amazon Prime free shipping. Make Some Noise: UE BOOM is the 360-degree speaker that drops bold, rich resonant sound in every direction with exceptional bass size. Up for Anything: UE BOOM has a versatile, go anywhere shape that is designed to be spontaneous. Life-Resistant: Colorful acoustic skin with plasma coating makes UE BOOM water and stain resistant. Live Wirelessly: Switch songs, adjust volume and take phone calls from up to 50 feet away. The rechargeable battery has 15 hours of playback. Double Up: Wirelessly connect two UE BOOMs together in stereo via the UE BOOM app to spread the sound and pump up the volume.
