Our Verdict
Ultimate Ears WONDERBOOM 2
Bose SoundLink Flex
The Ultimate Ears WONDERBOOM 2 is better than the Bose SoundLink Flex, though they have different strengths. The Ultimate Ears is a stereo speaker with a more open and wide-sounding soundstage. It has less compression present at max volume and significantly longer-lasting battery life, though this can vary depending on your usage. However, the Bose can produce a deeper bass and supports voice assistants through your smartphone.
