These sit in different size classes, so this is not a straight ranking comparison. The LG Xboom Bounce ranks #33 of 114 large speakers by sound quality at $96.99; the Bose Soundlink Flex 2nd gen ranks #37 of 173 medium speakers by sound quality at $159.
The LG Xboom Bounce is the longer-running pick. A tough, waterproof speaker that survives drops and extreme temperatures, with a long battery and multipoint pairing. It is rated for 30 hours of battery against 12 for the Bose Soundlink Flex 2nd gen. It keeps a wired aux input, which the Bose Soundlink Flex 2nd gen lacks. The tradeoff: Bass extension not as deep as the top speakers.
The Bose Soundlink Flex 2nd gen is the lighter choice. A small, rugged waterproof speaker with clear, well balanced mids, app EQ, aptX Adaptive and stereo pairing with a second unit. At 1.3 lbs (586 g) it weighs much less than the LG Xboom Bounce at 2.9 lbs (1.32 kg). It supports aptX Adaptive Bluetooth, which the LG Xboom Bounce 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.
Buy the LG Xboom Bounce at $96.99 for a large speaker, or the Bose Soundlink Flex 2nd gen at $159 for a medium speaker instead.
