Short answer: the Bose Soundlink Flex. It ranks #38 of 177 medium speakers by sound quality, rated 3.8/5, at $79.99. The Walla Sound ranks #163, rated 2.2/5, at $49.99, $30 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bose Soundlink Flex is the better-sounding, deeper-bass option. A small, rugged waterproof speaker that survives drops and floats, with a warm, bass forward sound for casual outdoor use. Its bass reaches about 56Hz 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: Warm sounding with overly boosted bass which drowns out midrange detail.
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 Bose Soundlink Flex at 1.3 lbs (589 g). It keeps a wired aux input, which the Bose Soundlink Flex lacks. The tradeoff: No bass, gets distorted when turned up.
Buy the Bose Soundlink Flex. It is rated higher for sound quality, and saving $30 with the Walla Sound does not make up for the sound-quality gap.
