These sit in different size classes, so this is not a straight ranking comparison. The Bose Soundlink Micro ranks #20 of 61 small speakers by sound quality at $99.99; the JBL Flip 4 ranks #79 of 173 medium speakers by sound quality at $70.
The Bose Soundlink Micro is the lighter choice. A 0.6 lbs (289 g) IP67 waterproof pocket speaker with a rugged rubberized coating, a built-in strap and 6-hour battery life. At 0.6 lbs (289 g) it weighs much less than the JBL Flip 4 at 1.1 lbs (510 g).
The JBL Flip 4 is the longer-running option. At 1.1 lbs (510 g), JBL Flip 4 combines 2x 40mm fullrange with Bluetooth and aux. It is rated for 12 hours of battery against 6 for the Bose Soundlink Micro. It keeps a wired aux input, which the Bose Soundlink Micro lacks. It plays in stereo from a single unit, unlike the Bose Soundlink Micro. The tradeoff: Battery failures are common.
Worth knowing: the JBL Flip 4 is discontinued, though it still ranks #79 of 173 medium speakers by sound quality, so a used unit beats most of what is still sold new. The JBL Flip 4’s replacement, the JBL Flip 7, is still sold new.
Buy the Bose Soundlink Micro at $99.99 for a small speaker, or the JBL Flip 4 at $70 for a medium speaker instead.
