Short answer: the Bose Soundlink Flex. It ranks #38 of 175 medium speakers by sound quality (rated 3.8/5) at $159 and is still sold new; the Bose Soundlink Mini 2 ranks #72 (rated 3.4/5) and is discontinued, so it is only an option used.
The Bose Soundlink Flex is the better-sounding, tougher choice. IP67 rated; rugged enough to survive drops from several feet and floats. It is rated IP67, while the Bose Soundlink Mini 2 has no water resistance. The catch: Warm sounding with overly boosted bass which drowns out midrange detail.
The case for the Bose Soundlink Mini 2: Compact aluminum build feels sturdy and dense. ~10 hour battery life; can pair to two devices at once and remembers up to 8. It keeps a wired aux input, which the Bose Soundlink Flex lacks. It plays in stereo from a single unit, unlike the Bose Soundlink Flex. The catch: Boosted upper bass like most Bose speakers.
Buy the Bose Soundlink Flex. It is rated higher for sound quality; the Bose Soundlink Mini 2 is no longer sold new.
