Short answer: the Harman Kardon Luna for better sound quality, the Soundcore Motion 100 for the lower price. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Soundcore Motion 100 ranks #39 at $47, $243.99 cheaper.
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
What the Soundcore Motion 100 offers: Use Oluv’s EQ for the flattest response Watch for: 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.
Buy the Harman Kardon Luna if sound quality is the priority over the price, or the Soundcore Motion 100 if the price is the priority over sound quality.
