Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (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).

Klipsch Groove/Heritage Groove: $89.00 Amazon eBay
Pros: Pretty balanced sound. Distinctive mid-century design with real wood veneer and a woven grille, unlike most plastic/rubber portables. ~8 hour battery life.
Cons: Not stereo. Bass doesn’t go as deep as others its size. Gets distorted at higher levels. Wouldn’t generally recommend these old speakers as they can’t compete with modern speakers for bass performance and features.
