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 2 ranks #91, rated 3.0/5, and costs $70, so there is not much of a tradeoff to weigh.
The case for the Tronsmart Mirtune C3: 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 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.
Why pick the Tribit Stormbox 2: A little better sounding than the Stormbox 1, less of a rolled off treble. The tradeoff: Drivers on the side, so it will have a rolled off treble listening to it face on.
Buy the Tronsmart Mirtune C3. It is rated higher for sound quality than the Tribit Stormbox 2 and costs less, so only choose the other one for a particular feature it does better.
If battery life is a priority, the Tribit Stormbox 2 is rated for 24 hours versus 12 hours for the Tronsmart Mirtune C3.
