Short answer: the Minirig 4. It ranks #7 of 177 medium speakers by sound quality, rated 4.3/5, at $229.95. The Walla Sound ranks #163, rated 2.2/5, at $49.99, $179.96 cheaper, which does not close the gap in sound quality.
The Minirig 4 is the better-sounding, deeper-bass option. A small, long lasting speaker that gets loud and can add a matching subwoofer, with a 30 hour battery. Its bass reaches about 56Hz before falling 10dB, against 90Hz for the Walla Sound. It is rated for 30 hours of battery against 8 for the Walla Sound. It has an adjustable EQ, which the Walla Sound lacks. The tradeoff: Calls itself splash resistant and has no official water rating.
The Walla Sound is the lighter option. 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 Minirig 4 at 1.2 lbs (550 g). The tradeoff: No bass, gets distorted when turned up.
Buy the Minirig 4. It is rated higher for sound quality, and saving $179.96 with the Walla Sound does not make up for the sound-quality gap.
