Short answer: the Soundcore 3/Soundcore Select 2. It ranks #61 of 150 medium speakers by sound quality, rated 3.4/5, at $59.99; the JBL Flip 4 ranks #72, rated 3.3/5, and costs $70, so there is little reason to consider the other one.
Why pick the Soundcore 3/Soundcore Select 2: Soundcore 3/Soundcore Select 2 uses 2x 38mm (1.5”) titanium diaphragm full-range drivers + 2x passive radiators. The tradeoff: Bass is limited by its 60Hz specification.
The case for the JBL Flip 4: At 510 g, JBL Flip 4 combines 2x 40mm fullrange with Bluetooth and aux. The catch: Bass is limited by its 66Hz specification.
Worth knowing: the JBL Flip 4 is discontinued, though it still ranks #72 of 150 medium speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Soundcore 3/Soundcore Select 2. It is rated higher for sound quality than the JBL Flip 4 and costs less, so only choose the other one for a particular feature it does better.
If battery life is a priority, the Soundcore 3/Soundcore Select 2 is rated for 24 hours versus 12 hours for the JBL Flip 4.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
