Short answer: the Tronsmart Mirtune C3 Plus. It ranks #84 of 182 medium speakers by sound quality, rated 3.3/5, at $49.99. The Tronsmart Mirtune C3 ranks #102, rated 3.1/5, at $29.99, $20 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Tronsmart Mirtune C3 Plus: 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.
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 noticeably less than the Tronsmart Mirtune C3 Plus at 1.8 lbs (810 g). The catch: 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 Tronsmart Mirtune C3 Plus. It is rated higher for sound quality, and saving $20 with the Tronsmart Mirtune C3 does not make up for the sound-quality gap.
