A compact size, stylish form factor, and solid sound performance help make Logitech's UE Boom a good choice for a portable speaker. The UE Boom's cylindrical shape is a different take on portable speakers, one that iLounge appreciated, saying it "has one of the nicest overall designs in its class." The design doesn't make it less portable, either, with PC Mag finding it "small enough to tuck into a bag." Logitech built the UE Boom with a cylindrical shape to deliver a 360-degree sound performance, and it works. ZDNet calls it a "top notch audio experience," and Mashable says it "offers outstanding sound quality for the price." The price is a little higher than our current Must-have portable speaker, the Jawbone JAMBOX, but the size and sound experience help justify the cost.
