The verdict

If you're looking for a speaker to accompany you on every summer adventure, the UE Wonderboom 2 is a great option. The lack of an integrated microphone is annoying since it means you can't access a voice assistant, but it's a small price to pay for a speaker that floats.

✓Liked: IP67 dust- and water-resistant, Connect two devices simultaneously, Pair to another Wonderboom 2 for stereo sound, Two-year warranty

✕Could be better: No microphone, Distortion increases with volume, microUSB charging
