UE has taken a great, affordable Bluetooth speaker and made it even better, delivering a weightier sound and some useful new features

Weighty bass, Long battery life, Outdoor sound mode, Stereo pairing feature

No Alexa or Google Assistant

This second iteration Wonderboom is every inch as good as the first model. It's an easy recommendation if you're after a compact Bluetooth speaker that will do it all, offer all-round protection and a bassy 360-degree sound. You can even stereo pair two together.

Great sound quality, Plenty of bass, Stereo pairing, Good battery life, Compact design

Uses older Micro-USB connection, The older model is almost just as good for less cash

A rugged little wonder that brings a mega boost to your outdoor soirées

Stellar sound for speaker this size; Stereo works a treat; Super rugged; Excellent value

Like a Tequila Sunrise, punchy in appearance, and deceptively effective, the Wonderboom 2 is a mighty delight. Ideal for taking to picnics to soundtrack your sandwich session or even if you’re looking to use one (or two) indoors to supercharge your audio set-up in the bedroom of your halls of residence. Audio quality is ramped up from its predecessor giving you better bass and more detail in the mid-range, whilst still being just as dinky and portable. Shake it, stir it, roll it, there’s nothing precious about it, apart from all the things that matter: size, sound, portability and price. We’ll take a Wonderboom 2. On the rocks. Somewhere sunny.

We would have enjoyed USB C for charging if only because most accessories are going that way. It also makes one more cable to pack if you’re planning to take your speaker with you on a vacation.

The Wonderboom 2 was released in 2019 for an RRP of £90 / $99 / €99 / CAD$130 / AUD$130.
