Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Flip 4 is the better pick: it ranks #83 of 175 medium speakers by sound quality (rated 3.3/5), against #125 (rated 2.7/5) for the Bose SoundLink Color II. If you want one new, the JBL Flip 7 replaces the JBL Flip 4 and is rated 4.2/5 at $89.95.
The JBL Flip 4 is the better-sounding, longer-running pick. 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 8 for the Bose SoundLink Color II. It is rated IPX7 against IPX4 for the Bose SoundLink Color II. It keeps a wired aux input, which the Bose SoundLink Color II lacks. Watch for: Battery failures are common.
Why pick the Bose SoundLink Color II: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. It supports AAC Bluetooth, which the JBL Flip 4 lacks. The catch: Boosted bass on Color II.
Buy the JBL Flip 4 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.
