Short answer: the Tronsmart Mirtune C3. It ranks #89 of 150 medium speakers by sound quality, rated 3.1/5, at $29.99; the Tribit Stormbox Mini+ ranks #121, rated 2.5/5, at $29.99. Close enough in price that the sound-quality gap is the deciding factor.
What the Tronsmart Mirtune C3 does well: Small and light at 530 g, with a racetrack driver and a tweeter rated for 30W, IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a lanyard. The catch: 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+: 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. 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+ at the same price, so it is the default pick unless a specific strength of the other one matters more to you.
