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 LG Xboom Grab ranks #104, rated 3.0/5, at $104.99, $54.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bose Soundlink Flex 2nd gen is the better-sounding option. A very portable 1.3 lbs (586 g), IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. It supports aptX Adaptive Bluetooth, which the LG Xboom Grab lacks. The tradeoff: 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.
The LG Xboom Grab is the longer-running option. 20 hour battery life: longer than the JBL Flip 7 or Ultimate Ears Boom 4. It is rated for 20 hours of battery against 12 for the Bose Soundlink Flex 2nd gen. The tradeoff: Bass extension not as deep as the top speakers.
Buy the Bose Soundlink Flex 2nd gen. It is rated higher for sound quality, and the $54.01 saving on the LG Xboom Grab is not enough to make up the difference.
