Short answer: the Tronsmart Mirtune C3 Plus. It ranks #75 of 150 medium speakers by sound quality, rated 3.3/5, at $49.99. The Soundcore 2 ranks #92, rated 3.0/5, at $29.99, $20 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Tronsmart Mirtune C3 Plus does well: 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 catch: 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.
Why pick the Soundcore 2: Soundcore 2 uses 2x 38mm fullrange. The tradeoff: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
Buy the Tronsmart Mirtune C3 Plus. It is rated higher for sound quality, and saving $20 with the Soundcore 2 does not make up for the sound-quality gap.
Battery life favors the Soundcore 2: rated for 24 hours against 12 hours for the Tronsmart Mirtune C3 Plus.
