Short answer: the Harman Kardon Luna. It ranks #26 of 182 medium speakers by sound quality, rated 4.0/5, at $290.99. The Bose SoundLink Revolve (Series II) ranks #53, rated 3.6/5, at $194, $96.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Harman Kardon Luna is the better-sounding, tougher pick. A fully waterproof speaker with fairly balanced, bass rich sound, a separate tweeter, and stereo pairing with a second unit. It is rated IP67 against IP55 for the Bose SoundLink Revolve (Series II). It charges over USB-C rather than Micro USB. Watch for: Boosted bass, and less detailed than higher-ranked speakers.
The Bose SoundLink Revolve (Series II) is the lighter option. A compact speaker that plays all around to fill a room, with a speakerphone mic and splash resistance. At 1.5 lbs (680 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It keeps a wired aux input, which the Harman Kardon Luna lacks. Watch for: RTINGS found it lacks low bass, so there’s little deep thump or rumble.
Buy the Harman Kardon Luna. It is rated higher for sound quality, and the $96.99 you would save on the Bose SoundLink Revolve (Series II) does not close the gap.
