Short answer: the Bose Soundlink Flex 2nd gen, if you are buying new. The Minirig 2 ranks higher than it (#9 vs #37 of 164 medium speakers, 4.3/5 vs 3.8/5) but is discontinued, so only consider it used; the Bose Soundlink Flex 2nd gen is still sold new at $159.
The Minirig 2 is the better-sounding, longer-running pick. Modular, can easily attach a subwoofer. It is rated for 40 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 catch: Calls itself splash resistant and has no official water rating.
The Bose Soundlink Flex 2nd gen is the tougher choice. A very portable 1.3 lbs (586 g), IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. It is rated IP67 against Splash resistant for the Minirig 2. It supports aptX Adaptive Bluetooth, which the Minirig 2 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 Bose Soundlink Flex 2nd gen new; the Minirig 2 is no longer sold new, so it only makes sense as a used find.

Bose Soundlink Flex 2nd gen: $159.00 Amazon eBay
Older model: the Bose Soundlink Flex (ranked lower, rated 3.8/5).
Smaller model: the Bose Soundlink Micro (rated 3.5/5).
Larger model: the Bose SoundLink Max (rated 4.3/5).
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.
