Short answer: the Bose Soundlink Flex 2nd gen. It ranks #35 of 144 medium speakers by sound quality, rated 3.8/5, at $159; the LG Xboom Go PL5 ranks #119, rated 2.4/5, and costs $179, so there is little reason to consider the other one.
Why pick the Bose Soundlink Flex 2nd gen: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. 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.
What the LG Xboom Go PL5 does well: 18 hour battery life; IPX5 rated. The catch: Barely any bass.
Buy the Bose Soundlink Flex 2nd gen. It is rated higher for sound quality than the LG Xboom Go PL5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
Bose Soundlink Flex 2nd gen: $159.00 Amazon eBay
Older model: the Bose Soundlink Flex (rated 3.8/5).
Pros: 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.
Cons: 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.
