Short answer: the Harman Kardon Luna if sound quality matters most, the W-King D8 Mini if price matters most. The Harman Kardon Luna ranks #26 of 175 medium speakers, rated 4.0/5, at $290.99. The W-King D8 Mini ranks #135, rated 2.6/5, at $49.99, $241 cheaper.
The Harman Kardon Luna is the better-sounding option. The sound is fairly balanced apart from the boosted bass. The catch: Boosted bass, and less detailed than higher-ranked speakers.
The W-King D8 Mini is the longer-running choice. 30W output with switchable indoor/outdoor EQ modes. It is rated for 24 hours of battery against 12 for the Harman Kardon Luna. It keeps a wired aux input, which the Harman Kardon Luna lacks. It has an adjustable EQ, which the Harman Kardon Luna lacks. The tradeoff: Recessed midrange, harsh treble.
Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the W-King D8 Mini when the price outweighs sound quality instead.
