Short answer: the Doss E-Go II, if you are buying new. The JBL Charge 3 ranks higher than it (#77 vs #124 of 150 medium speakers, 3.2/5 vs 2.5/5) but is discontinued, so only consider it used; the Doss E-Go II is still sold new at $39.90.
The case for 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.
What the Doss E-Go II does well: Very portable (water bottle sized), truly waterproof (IPX6), 12-hour battery life, excellent value for money, fast Bluetooth pairing. The tradeoff: Horribly bad unless turned up, still not great.
Buy the Doss E-Go II, since the JBL Charge 3 is discontinued and only worth hunting down used.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
