Short answer: the Soundcore Motion 300. It ranks #3 of 175 medium speakers by sound quality, rated 4.5/5, at $79.99; the Harman Kardon Luna ranks #26, rated 4.0/5, and costs $290.99, so there is little reason to consider the other one.
The Soundcore Motion 300 is the better-sounding, deeper-bass pick. Pretty deep bass for the small size. Its bass reaches about 50Hz before falling 10dB, against 57Hz for the Harman Kardon Luna. At 1.7 lbs (772 g) it weighs noticeably less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports LDAC Bluetooth, which the Harman Kardon Luna lacks. 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.
The case for the Harman Kardon Luna: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. The catch: Bass is limited by its 57Hz specification.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Harman Kardon Luna and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon $79.99 eBay
Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5). See every Soundcore Motion generation.
Same family: the Soundcore Motion 100 (smaller model, ranked lower, rated 3.7/5), the Soundcore Motion X500 (larger model, rated 4.1/5) and the Soundcore Motion X600 (larger model, rated 4.3/5).
Pros: 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. Beat the Marshall Stockwell III in Alan Ross’s live A/B. Measured bass extension of 50Hz (-10dB).
Cons: 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.

Harman Kardon Luna: $290.99 Amazon $290.99 eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5, released Mar 2026. It adds app control and adjustable EQ. See every Harman Kardon Luna generation.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
