Short answer: the Tronsmart Mirtune C3 Plus. It ranks #84 of 182 medium speakers by sound quality, rated 3.3/5, at $49.99; the JBL Grip ranks #98, rated 3.1/5, and costs $69.95, so there is not much of a tradeoff to weigh.
What the Tronsmart Mirtune C3 Plus does well: 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.
The JBL Grip is the lighter option. A small, fully waterproof speaker with app EQ, ambient lighting, Auracast linking and USB-C audio input. At 0.8 lbs (385 g) it weighs much less than the Tronsmart Mirtune C3 Plus at 1.8 lbs (810 g). The catch: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
Buy the Tronsmart Mirtune C3 Plus. It is rated higher for sound quality than the JBL Grip and costs less, so only choose the other one for a particular feature it does better.
