Short answer: the JBL Charge 6. It ranks #12 of 182 medium speakers by sound quality, rated 4.2/5, at $149.95. The Tronsmart Mirtune C3 Plus ranks #84, rated 3.3/5, at $49.99, $99.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Charge 6 is the better-sounding, longer-running choice. A waterproof medium speaker with a long battery and a power bank output, with more balanced sound than older Charge models. It is rated for 24 hours of battery against 12 for the Tronsmart Mirtune C3 Plus. It supports AAC Bluetooth, which the Tronsmart Mirtune C3 Plus lacks. Watch for: Still some boosted bass by default.
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. 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 JBL Charge 6. It is rated higher for sound quality, and the $99.96 you would save on the Tronsmart Mirtune C3 Plus does not close the gap.
