Ultimate Ears has performed well in many of our previous tests. For example, the UE Megaboom was test winner at last year’s test of more expensive travel speakers. We have also tested Wonderboom separately, but how does it perform compared to the competition? We like the rounded format and the string that fits on the soap shelf in the shower. It can handle it because it is well protected against the elements. Since last year, several new colour options along with two fun patterns have appeared.

The control is simple with large, clear buttons. A button is also used to connect two Wonderbooms, but no stereo sound is given. Unfortunately, the Boom app isn’t supported, so you can’t use it to hook up a bunch of speakers. Logitech claims it’s easier. We think it’s sad. It lacks a microphone, so you can’t use it for phone calls, or to get voice assistants. However, it promises a range of 30 metres, which is good.

The most important is how it sounds, and Wonderboom provides just as much fun as the look suggests. It plays louder than you might think, and delivers deep bass. But that’s not the only thing that impresses us. You also gets a clean mid range with a clear and well-defined sound. Moreover, the treble is clear, without harsh edges. Thanks to the omnidirectional sound, it’s well suited for a group of friends at the beach with everyone hearing the music equally good.

Conclusion

Ultimate Ears Wonderboom is an excellent, small Bluetooth speaker with many qualities and few issues. It has a neat design, is waterproof, plays both loudly and deeply, and has a great price. The only thing it really lacks is the ability to hook up in a stereo combination. Aside from that it’s a fantastic, well-sounding, little speaker, that you can bring along wherever it is needed. It is built to take a beating, and continues to play even if it’s pouring.
