Short answer: the W-King D320. It ranks #49 of 177 medium speakers by sound quality, rated 3.6/5, at $52.92; the Walla Sound ranks #163, rated 2.2/5, at $49.99. With prices this close, go by the sound-quality ranking rather than the cost.
The Walla Sound is the lighter choice. 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 W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: No bass, gets distorted when turned up.
The W-King D320 is the better-sounding, longer-running option. An affordable waterproof travel speaker with loud, punchy bass, long battery life, an aux input, microSD playback and app EQ. It is rated for 24 hours of battery against 8 for the Walla Sound. It is rated IP67 against IPX5 for the Walla Sound. It has an adjustable EQ, which the Walla Sound lacks. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Buy the W-King D320. It is rated higher for sound quality, and the $2.93 you would save on the Walla Sound does not close the gap.
