Short answer: the Tronsmart Mirtune C3 Plus. It ranks #84 of 182 medium speakers by sound quality, rated 3.3/5, at $49.99. The Soundcore 2 ranks #105, rated 3.0/5, at $29.99, $20 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Tronsmart Mirtune C3 Plus does well: An affordable waterproof speaker with a separate tweeter, app EQ, Auracast linking, stereo pairing and USB-C audio input. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. The tradeoff: In side by side tests by Clinch Audio Bass and Mateusz Cholewa, the Xiaomi Sound Party and Soundcore Boom 3i sounded more refined and fuller, and listeners described the C3 Plus’s treble as dull.
The Soundcore 2 is the longer-running, lighter pick. 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 Plus. At 0.7 lbs (318 g) it weighs much less than the Tronsmart Mirtune C3 Plus at 1.8 lbs (810 g). It keeps a wired aux input, which the Tronsmart Mirtune C3 Plus lacks. The catch: Bass is specified only down to 70Hz, so the low end is limited.
Buy the Tronsmart Mirtune C3 Plus. It is rated higher for sound quality, and saving $20 with the Soundcore 2 does not make up for the sound-quality gap.
