Short answer: the Tronsmart Mirtune S100, if you are buying new. The JBL Charge 3 ranks higher than it (#77 vs #84 of 150 medium speakers, 3.2/5 vs 3.1/5) but is discontinued, so only consider it used; the Tronsmart Mirtune S100 is still sold new at $79.99.
Why pick the JBL Charge 3: Doubles as a 6000mAh power bank for USB devices. ~20 hour battery life. The tradeoff: Less clarity than the Flip 4.
The case for the Tronsmart Mirtune S100: At 1.36 kg, Tronsmart Mirtune S100 combines 20W drivers with Bluetooth. The catch: Bass is limited by its ~64Hz specification.
Buy the Tronsmart Mirtune S100 new; the JBL Charge 3 is no longer sold new, so it only makes sense as a used find.
