Short answer: the Bose Soundlink Flex 2nd gen. It ranks #37 of 177 medium speakers by sound quality, rated 3.8/5, at $149. The LG Xboom Grab ranks #106, rated 3.0/5, at $100.98, $48.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bose Soundlink Flex 2nd gen is the better-sounding option. A small, rugged waterproof speaker with clear, well balanced mids, app EQ, aptX Adaptive and stereo pairing with a second unit. 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. A rugged waterproof speaker with elastic mounting straps, a long 20 hour battery, multipoint pairing and app room calibration. 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 $48.02 saving on the LG Xboom Grab is not enough to make up the difference.
