The UE Boom 2 is one of the finest Bluetooth speakers you can buy. Great sound, long battery life, distinct styling, and a waterproof exterior make it stand out in the crowded group of competitors in the portable speaker arena.It's also one of the pricier speakers on the market, normally selling for the premium of price of $200. With the support of a strong brand name and stellar reviews, the Boom 2 almost never dips below this price.It happens to be on sale today. At least in a couple of color variations. The royal and baby blue 'Brainfreeze Edition' is currently priced at $166.42, and the obnoxiously bright pink and orange 'Tropical Edition' is even lower at $161.16.The irregular numbers in the prices make me think this is Amazon clearing inventory on less popular colors, not an official UE sale. That means that these prices may be highly volatile and could change at any moment. If you are in the market for a Boom 2, and don't mind some bright colors, then now is a great time to buy one.Source: Brainfreeze Edition, Tropical Edition
