Short answer: the Harman Kardon Luna 2 if sound quality matters most, the Walla Sound if price matters most. The Harman Kardon Luna 2 ranks #23 of 142 medium speakers at $199.95. The Walla Sound ranks #129 at $49.99, $149.96 cheaper.
What the Harman Kardon Luna 2 offers: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).
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 Harman Kardon Luna 2 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.
