Short answer: both are discontinued, so this only matters if you are buying used. Used, the Tribit Stormbox Pro is the better pick: it ranks #46 of 175 medium speakers by sound quality (rated 3.7/5), against #83 (rated 3.3/5) for the JBL Flip 4. If you want one new, the JBL Flip 7 replaces the JBL Flip 4 and is rated 4.2/5 at $89.95.
The Tribit Stormbox Pro is the better-sounding, deeper-bass pick. 24 hour battery life (60% volume, XBass off); doubles as a power bank. Its bass reaches about 58Hz before falling 10dB, against 66Hz for the JBL Flip 4. It is rated for 24 hours of battery against 12 for the JBL Flip 4. It supports aptX Bluetooth, which the JBL Flip 4 lacks. The tradeoff: Bottom woofer was fixed in a later firmware, upgrade for best sound.
The JBL Flip 4 is the lighter option. 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 Tribit Stormbox Pro at 2.2 lbs (980 g). It links with other speakers (Connect+ up to 100 speakers), which the Tribit Stormbox Pro cannot. It plays in stereo from a single unit, unlike the Tribit Stormbox Pro. The catch: Battery failures are common.
Buy the Tribit Stormbox Pro only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Flip 7, which replaces the JBL Flip 4.
