Ultimate Ears is known for its line of rugged, waterproof speakers that come in bright colors and offer high-quality sound at prices that aren't exorbitant.
In October, Ultimate Ears expanded its product lineup with two new flagship devices, the Blast and the Megablast, successors to the Boom 2 and the Megaboom, with revamped designs and, for the first time, Wi-Fi support with Amazon Alexa integration.

I tested the new Ultimate Ears speakers, and I liked the addition of Alexa integration, especially in a wire-free device. There were, however, some limitations and caveats that may not make this the best speaker for everyone.
Design
Blast and Megablast don't look too different from previous-generation Ultimate Ears speakers, but they do sport a new, more modern design with a flatter top and less rounded edges for a decidedly cleaner and sleeker appearance.
They use the same cylindrical design as past speakers, offering 360 degree sound. The top and the bottom of the Blast and Megablast feature a soft rubber material with bluetooth/power/Alexa buttons and access to a charging port, while most of the rest of the speaker is made from a matching mesh.

Both speakers continue to feature prominent "+" and "-" buttons that are used for controlling volume. Some people don't like these buttons because of the resemblance to a cross, but I've always been a fan of the bold look and easy-access volume controls. The speakers each come in a range of colors, including Blue Steel, Merlot, Blizzard, and Graphite. The Megablast I have on hand is Blue Steel, while the Blast is Merlot, and both colors are subdued and even elegant, able to match well with any decor.
