Short answer: the Bose Soundlink Flex on measured sound quality, the Tribit Stormbox Mini+ on price. The Bose Soundlink Flex ranks #38 of 175 medium speakers, rated 3.8/5, at $159. The Tribit Stormbox Mini+ ranks #142, rated 2.5/5, at $31.99, $127.01 cheaper.
The Bose Soundlink Flex is the better-sounding choice. IP67 rated; rugged enough to survive drops from several feet and floats. Watch for: Warm sounding with overly boosted bass which drowns out midrange detail.
Why pick the Tribit Stormbox Mini+: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. It supports AAC Bluetooth, which the Bose Soundlink Flex lacks. It keeps a wired aux input, which the Bose Soundlink Flex lacks. It has an adjustable EQ, which the Bose Soundlink Flex lacks. The tradeoff: Not a great sounding speaker, really weak bass.
Buy the Bose Soundlink Flex if sound quality matters more than the price. Buy the Tribit Stormbox Mini+ if the price matters more than sound quality.
