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 S100 ranks #97, rated 3.1/5, at $79.99, $55.85 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Xiaomi Sound Party is the better-sounding, deeper-bass option. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. Its bass reaches about 54Hz before falling 10dB, against 64Hz for the Tronsmart Mirtune S100. It is rated for 26 hours of battery against 20 for the Tronsmart Mirtune S100. Watch for: The sound evidence is mixed rather than universally glowing.
What the Tronsmart Mirtune S100 does well: A waterproof speaker with long battery life for outdoor and casual listening. It keeps a wired aux input, which the Xiaomi Sound Party lacks.
Buy the Xiaomi Sound Party. It is rated higher for sound quality, and the $55.85 you would save on the Tronsmart Mirtune S100 does not close the gap.
