Short answer: the Xiaomi Sound Party on measured sound quality, the Tronsmart Mirtune C3 on price. The Xiaomi Sound Party ranks #20 of 182 medium speakers, rated 4.1/5, at $135.84. The Tronsmart Mirtune C3 ranks #102, rated 3.1/5, at $29.99, $105.85 cheaper.
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. The tradeoff: The sound evidence is mixed rather than universally glowing.
The Tronsmart Mirtune C3 is the lighter choice. 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 Xiaomi Sound Party at 2.6 lbs (1.2 kg). The tradeoff: 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.
Buy the Xiaomi Sound Party when sound quality outweighs the price for you, and the Tronsmart Mirtune C3 when the price outweighs sound quality instead.
