Short answer: the Soundcore 3/Soundcore Select 2. It ranks #61 of 150 medium speakers by sound quality, rated 3.4/5, at $59.99. The Tronsmart Mirtune C3 Plus ranks #75, rated 3.3/5, at $49.99, $10 cheaper, which does not close the gap in sound quality.
The case for the Soundcore 3/Soundcore Select 2: Soundcore 3/Soundcore Select 2 uses 2x 38mm (1.5”) titanium diaphragm full-range drivers + 2x passive radiators. The catch: Bass is limited by its 60Hz specification.
Why pick the Tronsmart Mirtune C3 Plus: A racetrack woofer and a tweeter rated for 50W, with IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a detachable lanyard, at 0.81 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 Soundcore 3/Soundcore Select 2. It is rated higher for sound quality, and saving $10 with the Tronsmart Mirtune C3 Plus does not make up for the sound-quality gap.
If battery life is a priority, the Soundcore 3/Soundcore Select 2 is rated for 24 hours versus 12 hours for the Tronsmart Mirtune C3 Plus.
