Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; the Walla Sound ranks #163, rated 2.2/5, and costs $49.99, so there is little reason to consider the other one.
The EarFun Uboom L is the better-sounding, deeper-bass choice. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. Its bass reaches about 56Hz before falling 10dB, against 90Hz for the Walla Sound. It is rated for 16 hours of battery against 8 for the Walla Sound. It is rated IP67 against IPX5 for the Walla Sound. The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
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 EarFun Uboom L at 1.4 lbs (650 g). The tradeoff: No bass, gets distorted when turned up.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Walla Sound and costs less, so only choose the other one for a particular feature it does better.
