Short answer: the Tronsmart Mirtune C3. It ranks #102 of 182 medium speakers by sound quality, rated 3.1/5, at $29.99; the Soundcore 2 ranks #105, rated 3.0/5, at $29.99. Close enough in price that the sound-quality gap is the deciding factor.
The case for the Tronsmart Mirtune C3: A small, light waterproof speaker at a budget price, with Auracast multi speaker sync, stereo pairing, USB-C audio input and app EQ. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. 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 Soundcore 2 is the longer-running, lighter option. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 12 for the Tronsmart Mirtune C3. At 0.7 lbs (318 g) it weighs much less than the Tronsmart Mirtune C3 at 1.2 lbs (530 g). It keeps a wired aux input, which the Tronsmart Mirtune C3 lacks. The catch: Bass is specified only down to 70Hz, so the low end is limited.
Buy the Tronsmart Mirtune C3. It is rated higher for sound quality than the Soundcore 2 at the same price, so it is the default pick unless a specific strength of the other one matters more to you.
