Short answer: the Tronsmart Mirtune C3. Both are rated 3.1/5 for sound quality (#102 and #97 of 182 medium speakers), and the Tronsmart Mirtune C3 costs $29.99 against $79.99 for the Tronsmart Mirtune S100, so with nothing between them on sound quality, price settles it.
The Tronsmart Mirtune C3 is the lighter option. A small, light waterproof speaker at a budget price, with Auracast multi speaker sync, stereo pairing, USB-C audio input and app EQ. At 1.2 lbs (530 g) it weighs much less than the Tronsmart Mirtune S100 at 3 lbs (1.36 kg). 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 Tronsmart Mirtune S100 is the longer-running pick. 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. It keeps a wired aux input, which the Tronsmart Mirtune C3 lacks.
Buy the Tronsmart Mirtune C3. Both are rated the same for sound quality, and it costs $50 less than the Tronsmart Mirtune S100.
