Short answer: the Harman Kardon Luna 2. It ranks #25 of 182 medium speakers by sound quality (rated 4.1/5) at $199.95 and is still sold new; the JBL Flip 5 ranks #79 (rated 3.3/5) and is discontinued, so it is only an option used. The JBL Flip 5’s replacement, the JBL Flip 7, is rated 4.2/5 at $149.95.
The Harman Kardon Luna 2 is the better-sounding choice. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The JBL Flip 5 is the lighter option. A compact, light waterproof speaker with a carry strap and USB-C charging. At 1.2 lbs (540 g) it weighs noticeably less than the Harman Kardon Luna 2 at 1.6 lbs (735 g). The catch: Boosted upper bass.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality; the JBL Flip 5 is no longer sold new.
