Short answer: the Bose Soundlink Flex for better sound quality, the LG Xboom Grab for the lower price. The Bose Soundlink Flex ranks #36 of 142 medium speakers at $155.78. The LG Xboom Grab ranks #85 at $97.73, $58.05 cheaper.
What the Bose Soundlink Flex offers: IP67 rated; rugged enough to survive drops from several feet and floats. Around 12 hours of battery at moderate volume. Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail
What the LG Xboom Grab offers: 20 hour battery life - longer than the JBL Flip 7 or UE Boom 4. IP67 rated with elastic mounting straps. App unlocks AI room calibration, EQ, and light-strip customization; multipoint pairing. Watch for: Bass extension not as deep as the top speakers. Overpriced. This may move around in the rankings as we get better sound samples
Buy the Bose Soundlink Flex when sound quality outweighs the price for you, and the LG Xboom Grab when the price outweighs sound quality instead.
There is a real battery-life gap here: the LG Xboom Grab is rated for 20 hours, the Bose Soundlink Flex only 12 hours.
