Short answer: the Tronsmart Mirtune C3. Both are rated 3.1/5 for sound quality (#102 and #98 of 182 medium speakers), and the Tronsmart Mirtune C3 costs $29.99 against $69.95 for the JBL Grip, and with sound quality even, the cheaper one is the better buy.
The JBL Grip is the lighter pick. 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 noticeably less than the Tronsmart Mirtune C3 at 1.2 lbs (530 g). Watch for: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
What the Tronsmart Mirtune C3 does well: A small, light waterproof speaker at a budget price, with Auracast multi speaker sync, stereo pairing, USB-C audio input and app EQ. The catch: In GiT’s three way blind test it came behind the Creative Muvo Go and Xiaomi Sound Outdoor, sounding good only on sparse tracks, and listeners in AudioPro Reviews’ comparison found the JBL Flip 6 fuller with more bass.
Buy the Tronsmart Mirtune C3. Both are rated the same for sound quality, and it costs $39.96 less than the JBL Grip.
