Short answer: the Bose Soundlink Flex on measured sound quality, the Walla Sound on price. The Bose Soundlink Flex ranks #36 of 142 medium speakers at $155.78. The Walla Sound ranks #129 at $49.99, $105.79 cheaper.
What the Bose Soundlink Flex offers: IP67 rated; rugged enough to survive drops from several feet and floats. Around 12 hours of battery at moderate volume. Watch for: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail
What the Walla Sound offers: IPX5 water resistant, 8-hour battery life, shockproof construction, Bluetooth 5.0, MicroSD card support, AUX input, built-in HD microphone, voice assistant compatible, lightweight 300g Watch for: No bass, gets distorted when turned up. Harsh upper mids.
Buy the Bose Soundlink Flex when sound quality outweighs the price for you, and the Walla Sound when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Walla Sound. It ranks near the bottom of the 142 medium speakers, so look higher up the list instead.
