Short answer: the KEF Muo gen2 if sound quality matters most, the Walla Sound if price matters most. The KEF Muo gen2 ranks #76 of 142 medium speakers at $249.99. The Walla Sound ranks #129 at $49.99, $200 cheaper.
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.
What the KEF Muo gen2 offers: KEF seemed to have fixed the rolled off treble and overall balance Watch for: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.
Buy the Walla Sound when the price outweighs sound quality for you, and the KEF Muo gen2 when sound quality outweighs the price 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.
Battery life favors the KEF Muo gen2: rated for 24 hours against 8 hours for the Walla Sound.
