Short answer: the Harman Kardon Luna 2. It ranks #25 of 177 medium speakers by sound quality, rated 4.1/5, at $199.95. The JBL Grip ranks #98, rated 3.1/5, at $69.95, $130 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Grip is the lighter pick. A small, fully waterproof speaker with app EQ, ambient lighting, Auracast linking and USB-C audio input. At 0.8 lbs (385 g) it weighs much less than the Harman Kardon Luna 2 at 1.6 lbs (735 g). The tradeoff: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
The Harman Kardon Luna 2 is the better-sounding option. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality, and saving $130 with the JBL Grip does not make up for the sound-quality gap.
