Short answer: the Tronsmart T8. It ranks #54 of 182 medium speakers by sound quality, rated 3.6/5, at $49.99; the Tronsmart Mirtune C3 Plus ranks #84, rated 3.3/5, at $49.99. The price gap is small enough that the sound-quality ranking should decide it.
The Tronsmart T8 is the better-sounding, longer-running choice. An affordable waterproof speaker with upward firing drivers that spread sound around, plus lights, app EQ, an aux input and stereo pairing. It is rated for 18 hours of battery against 12 for the Tronsmart Mirtune C3 Plus. It keeps a wired aux input, which the Tronsmart Mirtune C3 Plus lacks. The tradeoff: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass.
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. 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.
Buy the Tronsmart T8. It is rated higher for sound quality than the Tronsmart Mirtune C3 Plus at the same price, so only choose the other one for a particular feature it does better.
