As with the UE Roll, the Boom2 and Megaboom have a solid build, minimalistic design, along with variations of vibrant colours. There is very little difference between the two units, with the Megaboom, almost simply, just a larger Boom2.

Logitech subsidary Ultimate Ear's original UE Boom was widely celebrated as one of the best portable Bluetooth speakers you could buy. With the UE Boom 2, Ultimate Ears has iterated with a speaker that's better, but a little pricier.

Great sound quality for form factor; Long Bluetooth range; Light; portable design

Struggles with sub-bass frequencies; Slight distortion at higher volumes

Ultimate Ears has become more of a household name since its inception by then-Logitech (now just Logi), since releasing a variety of Bluetooth speakers to the market. The first UE Boom, released back in 2013, was one of the best small-scale portable speakers we'd ever heard, all things considered,...

Great 360-degree sound for this size; Decent battery life; Full-on waterproofing (now including ports; Colourful design; Stereo pairing possible; Great app with preset equaliser settings

Bass has its limits; Not dramatically different from first model; It's pricey; Would like more equaliser controls

The UE Boom 2 has inherited its design from the last years UE Boom model that my colleague reviewed. Just a little twitch in push buttons, the power button has no markings now and the charging and auxiliary jack acquire a rubber flap, that's all, in form factor only.

Robust build; Loud and clear sound output; Waterproof; Can be connected with unlimited UE boom 2; Amazing battery life; Full control over sound settings

Sound distorts at high volume; Costly

Ultimate Ears' line of BOOM speakers recently got updated with the arrival of the BOOM 2 speaker. The BOOM 2 shares the same footprint as the original BOOM, but has been updated with a few nifty features. Among these is wake-by-bluetooth and stop/start/pause slapping capability.

Excellent sound quality speedy and efficient delivery.

This one is quite loud and sounds awesome too

Puts out a lot of sound for such a small speaker. Sound quality is also pretty good and plenty loud for any room in the house or outside patio. Fits perfectly into my car's cup holder at chest level so I can use it while driving - nice bonus! EQ customization phone app is pretty cool.
