Short answer: the Harman Kardon Luna if sound quality matters most, the Walla Sound if price matters most. The Harman Kardon Luna ranks #26 of 177 medium speakers, rated 4.0/5, at $290.99. The Walla Sound ranks #163, rated 2.2/5, at $49.99, $241 cheaper.
The Harman Kardon Luna is the better-sounding, deeper-bass choice. A fully waterproof speaker with fairly balanced, bass rich sound, a separate tweeter, and stereo pairing with a second unit. Its bass reaches about 57Hz before falling 10dB, against 90Hz for the Walla Sound. It is rated for 12 hours of battery against 8 for the Walla Sound. It is rated IP67 against IPX5 for the Walla Sound. The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
The Walla Sound is the lighter pick. A small shockproof speaker with an aux input, microSD playback and a built in microphone. At 0.7 lbs (300 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. The tradeoff: No bass, gets distorted when turned up.
Buy the Harman Kardon Luna if sound quality matters more than the price. Buy the Walla Sound if the price matters more than sound quality.
