Short answer: the JBL Flip 7, if you are buying new. The JBL Flip 4 ranks higher than the W-King D8 Mini (#83 vs #135 of 175 medium speakers) but is discontinued; its replacement, the JBL Flip 7, is rated 4.2/5 at $89.95 and is still sold new.
The JBL Flip 4 is the better-sounding, lighter choice. At 1.1 lbs (510 g), JBL Flip 4 combines 2x 40mm fullrange with Bluetooth and aux. At 1.1 lbs (510 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). Watch for: Battery failures are common.
The W-King D8 Mini is the longer-running option. 30W output with switchable indoor/outdoor EQ modes. It is rated for 24 hours of battery against 12 for the JBL Flip 4. It has an adjustable EQ, which the JBL Flip 4 lacks. It charges over USB-C rather than Micro USB. The tradeoff: Recessed midrange, harsh treble.
