Soundcore Motion 300 vs Harman Kardon Luna

Last updated: August 28, 2026

Short answer: the Soundcore Motion 300. It ranks #2 of 136 medium speakers by sound quality at $79.99; the Harman Kardon Luna ranks #22 and costs $290.99, so there is little reason to consider the other one.

What the Soundcore Motion 300 offers: 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. Try the Uboom L EQs from Oluv for a more neutral sound. Watch for: 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. Slight bass distortion when turned up.

What the Harman Kardon Luna offers: Pretty balanced sound besides the boosted bass. Watch for: Not stereo. Boosted bass, not as detailed as higher ranked speakers

Buy the Soundcore Motion 300. It ranks higher for sound quality than the Harman Kardon Luna and costs less, which settles it without a real tradeoff to make.
