Short answer: the JBL Charge 6, if you are buying new. The JBL Charge 4 ranks higher than the Tronsmart Mirtune C3 Plus (#59 vs #84 of 182 medium speakers) but is discontinued; its replacement, the JBL Charge 6, is rated 4.2/5 at $149.95 and is still sold new.
The JBL Charge 4 is the longer-running option. A rugged waterproof speaker that floats, charges your phone, lasts a long time per charge and links with other JBL speakers. It is rated for 20 hours of battery against 12 for the Tronsmart Mirtune C3 Plus. It keeps a wired aux input, which the Tronsmart Mirtune C3 Plus lacks. The tradeoff: 1 Oval driver.
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. It has an adjustable EQ, which the JBL Charge 4 lacks. 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, the replacement for the discontinued JBL Charge 4; it is rated higher for sound quality than the Tronsmart Mirtune C3 Plus.
