Short answer: the Xiaomi Sound Party. It ranks #20 of 182 medium speakers by sound quality, rated 4.1/5, at $135.84. The Tronsmart Mirtune C3 Plus ranks #84, rated 3.3/5, at $49.99, $85.85 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Xiaomi Sound Party is the better-sounding, longer-running pick. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. It is rated for 26 hours of battery against 12 for the Tronsmart Mirtune C3 Plus. Watch for: The sound evidence is mixed rather than universally glowing.
The Tronsmart Mirtune C3 Plus is the lighter option. 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 noticeably less than the Xiaomi Sound Party at 2.6 lbs (1.2 kg). 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.
Buy the Xiaomi Sound Party. It is rated higher for sound quality, and the $85.85 you would save on the Tronsmart Mirtune C3 Plus does not close the gap.
