Short answer: the Harman Kardon Luna 2. It ranks #25 of 164 medium speakers by sound quality (rated 4.1/5) at $199.95 and is still sold new; the Soundcore Motion 100 ranks #45 (rated 3.7/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna 2 is the better-sounding choice. Articulate, spacious midrange with precise imaging and instrument separation. The tradeoff: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Soundcore Motion 100 is the lighter pick. At 1.3 lbs (575 g) it weighs noticeably less than the Harman Kardon Luna 2 at 1.6 lbs (735 g). It supports LDAC Bluetooth, which the Harman Kardon Luna 2 lacks. It plays in stereo from a single unit, unlike the Harman Kardon Luna 2. The tradeoff: Not very deep bass, slight distortion.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality; the Soundcore Motion 100 is no longer sold new.

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).

Soundcore Motion 100: $47 Discontinued eBay
Larger models: the Soundcore Motion 300 (ranked higher, rated 4.5/5), the Soundcore Motion X500 (rated 4.1/5) and the Soundcore Motion X600 (rated 4.3/5).
Pros: Use Oluv’s EQ for the flattest response. Measured bass extension of 65Hz (-10dB).
Cons: Not very deep bass, slight distortion. Real-world battery falls well short of the 12-hour claim at higher volumes (closer to 4 hours at max). Charging takes about 5 hours; no charge-out for other devices. Discontinued and no longer sold new.
