Short answer: the Tronsmart Mirtune C3, if you are buying new. The JBL Charge 3 ranks higher than it (#77 vs #89 of 150 medium speakers, 3.2/5 vs 3.1/5) but is discontinued, so only consider it used; the Tronsmart Mirtune C3 is still sold new at $29.99.
What the JBL Charge 3 does well: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. The catch: Less clarity than the Flip 4.
Why pick the Tronsmart Mirtune C3: Small and light at 530 g, with a racetrack driver and a tweeter rated for 30W, IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a lanyard. 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, since the JBL Charge 3 is discontinued and only worth hunting down used.
