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 Tronsmart Mirtune S100 ranks #97, rated 3.1/5, and costs $79.99, so there is little reason to consider the other one.
The Tronsmart Mirtune C3 Plus is the lighter pick. An affordable waterproof speaker with a separate tweeter, app EQ, Auracast linking, stereo pairing and USB-C audio input. At 1.8 lbs (810 g) it weighs much less than the Tronsmart Mirtune S100 at 3 lbs (1.36 kg). Watch for: 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 Tronsmart Mirtune S100 is the longer-running choice. A waterproof speaker with long battery life for outdoor and casual listening. It is rated for 20 hours of battery against 12 for the Tronsmart Mirtune C3 Plus. It keeps a wired aux input, which the Tronsmart Mirtune C3 Plus lacks.
Buy the Tronsmart Mirtune C3 Plus. It is rated higher for sound quality than the Tronsmart Mirtune S100 and costs less, so only choose the other one for a particular feature it does better.
