Short answer: the JBL Charge 6 for better sound quality, the Tronsmart Mirtune C3 for the lower price. The JBL Charge 3 ranks higher than the Tronsmart Mirtune C3 (#90 vs #102 of 182 medium speakers) but is discontinued. Its replacement, the JBL Charge 6, is rated 4.2/5 at $149.95; the Tronsmart Mirtune C3 is rated 3.1/5 at $29.99, $119.96 cheaper.
The JBL Charge 3 is the longer-running choice. 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. It keeps a wired aux input, which the Tronsmart Mirtune C3 lacks. It plays in stereo from a single unit, unlike the Tronsmart Mirtune C3. The tradeoff: Less clarity than the JBL Flip 4.
The Tronsmart Mirtune C3 is the lighter choice. A small, light waterproof speaker at a budget price, with Auracast multi speaker sync, stereo pairing, USB-C audio input and app EQ. At 1.2 lbs (530 g) it weighs noticeably less than the JBL Charge 3 at 1.8 lbs (800 g). It has an adjustable EQ, which the JBL Charge 3 lacks. It charges over USB-C rather than Micro USB. The tradeoff: 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 if price matters most. For better sound quality, the JBL Charge 6, the replacement for the discontinued JBL Charge 3, is rated higher but costs $149.95.
