Bose Soundlink Flex 2nd gen vs LG Xboom Grab

What the Bose Soundlink Flex 2nd gen offers: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. The second generation adds a Bose app with 3-band EQ, better-placed controls and stereo pairing with another Bose Soundlink Flex 2nd gen. It supports AAC and aptX Adaptive in addition to SBC, making it a stronger wireless option than most small rivals. Watch for: 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 claimed battery life is only 12 hours, and some owners report accelerated standby drain after firmware updates. It is expensive for its size, so the added app and codec support, not a transformational sound upgrade over the original, are the main reasons to choose it.

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

If battery life is a priority, the LG Xboom Grab is rated for 20 hours versus 12 hours for the Bose Soundlink Flex 2nd gen.
