Short answer: the Tronsmart Mirtune C3. It ranks #102 of 182 medium speakers by sound quality, rated 3.1/5, at $29.99; the Tribit Stormbox Mini+ ranks #148, rated 2.5/5, and costs $39.99, which makes this an easy call rather than a real tradeoff.
The Tronsmart Mirtune C3 is the better-sounding choice. A small, light waterproof speaker at a budget price, with Auracast multi speaker sync, stereo pairing, USB-C audio input and app EQ. The tradeoff: In GiT’s three way blind test it came behind the Creative Muvo Go and Xiaomi Sound Outdoor, sounding good only on sparse tracks, and listeners in AudioPro Reviews’ comparison found the JBL Flip 6 fuller with more bass.
The case for the Tribit Stormbox Mini+: An inexpensive waterproof speaker packed with features, including app EQ, an aux input, microSD playback and stereo pairing. It supports AAC Bluetooth, which the Tronsmart Mirtune C3 lacks. It keeps a wired aux input, which the Tronsmart Mirtune C3 lacks. It plays in stereo from a single unit, unlike the Tronsmart Mirtune C3. Watch for: Not a great sounding speaker, really weak bass.
Buy the Tronsmart Mirtune C3. It is rated higher for sound quality than the Tribit Stormbox Mini+ and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
