Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (ranked lower, rated 4/5).
Pros: 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.
Cons: 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).

Tozo PA2: $39.99 Amazon eBay
Pros: IPX8 rated, rugged fabric-wrapped design. App offers 16 EQ modes and TWS dual-pairing with a second PA2.
Cons: Quite a bit of bass distortion thudding as you turn the volume up. Bass not that deep. The Tozo PA1 totally outclasses it.
