Short answer: the Bose Soundlink Flex 2nd gen. It ranks #37 of 172 medium speakers by sound quality, rated 3.8/5, at $159. The Klipsch Groove ranks #112, rated 2.8/5, at $89, $70 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bose Soundlink Flex 2nd gen is the better-sounding, longer-running choice. A very portable 1.3 lbs (586 g), IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. It is rated for 12 hours of battery against 8 for the Klipsch Groove. At 1.3 lbs (586 g) it weighs noticeably less than the Klipsch Groove at 1.7 lbs (770 g). It is rated IP67 against IPX4 for the Klipsch Groove. The catch: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing.
Why pick the Klipsch Groove: Pretty balanced sound in a compact, splash-resistant form factor. It keeps a wired aux input, which the Bose Soundlink Flex 2nd gen lacks. The catch: Bass doesn’t go as deep as class leaders.
Buy the Bose Soundlink Flex 2nd gen. It is rated higher for sound quality, and saving $70 with the Klipsch Groove does not make up for the sound-quality gap.
