Short answer: the Sony ULT Field 3 if sound quality matters most, the Walla Sound if price matters most. The Sony ULT Field 3 ranks #60 of 142 medium speakers at $138. The Walla Sound ranks #129 at $49.99, $88.01 cheaper.
What the Sony ULT Field 3 offers: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Watch for: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off. Lost to the JBL Charge 6 in a side-by-side comparison despite being the larger speaker.
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 Sony ULT Field 3 if sound quality is the priority over the price, or the Walla Sound if the price is the priority over sound quality.
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.
Battery life favors the Sony ULT Field 3: rated for 24 hours against 8 hours for the Walla Sound.
