Short answer: the JBL Flip 7, if you are buying new. The JBL Flip 4 ranks higher than the Marshall Emberton II (#83 vs #127 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 pick. 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 noticeably less than the Marshall Emberton II at 1.5 lbs (700 g). It keeps a wired aux input, which the Marshall Emberton II lacks. Watch for: Battery failures are common.
The Marshall Emberton II is the longer-running option. 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. It is rated for 30 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: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the JBL Flip 7, the replacement for the discontinued JBL Flip 4; it is rated higher for sound quality than the Marshall Emberton II.
