Short answer: the Tronsmart Mirtune C3 Plus. It ranks #84 of 182 medium speakers by sound quality (rated 3.3/5) at $49.99 and is still sold new; the JBL Charge 3 ranks #90 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Charge 3’s replacement, the JBL Charge 6, is rated 4.2/5 at $149.95.
The case for 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 3 lacks. It charges over USB-C rather than Micro USB. 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 JBL Charge 3 is the longer-running pick. A waterproof speaker with long battery life, a speakerphone and a big battery that charges your phone. 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. It plays in stereo from a single unit, unlike the Tronsmart Mirtune C3 Plus. The tradeoff: Less clarity than the JBL Flip 4.
Buy the Tronsmart Mirtune C3 Plus. It is rated higher for sound quality, and the JBL Charge 3 is discontinued, so it is only available used.
