Harman Kardon Luna 2 vs Soundcore Motion 300

Last updated: September 1, 2026

Short answer: the Soundcore Motion 300. It ranks #2 of 138 medium speakers by sound quality at $79.99; the Harman Kardon Luna 2 ranks #22 and costs $199.95, so there is not much of a tradeoff to weigh.

The case for the Harman Kardon Luna 2: 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. The catch: 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.

On the Soundcore Motion 300 side: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. The tradeoff: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers.

Buy the Soundcore Motion 300. It ranks higher for sound quality than the Harman Kardon Luna 2 and costs less, so the other one has nothing left to offer.
