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 JBL Charge 3 ranks #77, rated 3.2/5, and costs $80, which makes this an easy call rather than a real tradeoff.
The case for 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. 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.
Why pick the JBL Charge 3: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. The catch: Less clarity than the Flip 4.
One note: the JBL Charge 3 is discontinued and no longer widely available new.
Buy the Tronsmart Mirtune C3 Plus. It is rated higher for sound quality than the JBL Charge 3 and costs less, which makes it the one to get unless you need something the other one does better.
There is a real battery-life gap here: the JBL Charge 3 is rated for 20 hours, the Tronsmart Mirtune C3 Plus only 12 hours.
