Short answer: the Xiaomi Sound Outdoor. It ranks #44 of 150 medium speakers by sound quality, rated 3.7/5, at $54.99. The Tronsmart Mirtune C3 ranks #89, rated 3.1/5, at $29.99, $25 cheaper, which does not close the gap in sound quality.
Why pick the Xiaomi Sound Outdoor: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. The catch: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
What the Tronsmart Mirtune C3 does well: Small and light at 530 g, with a racetrack driver and a tweeter rated for 30W, IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a lanyard. 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 Outdoor. It is rated higher for sound quality, and the $25 you would save on the Tronsmart Mirtune C3 does not close the gap.

The Two Speakers In Full
Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.
