Short answer: the Harman Kardon Luna on measured sound quality, the Klipsch Groove on price. The Harman Kardon Luna ranks #25 of 157 medium speakers, rated 4.0/5, at $290.99. The Klipsch Groove ranks #105, rated 2.8/5, at $9, $281.99 cheaper.
The Harman Kardon Luna is the better-sounding, longer-running choice. The sound is fairly balanced apart from the boosted bass. It is rated for 12 hours of battery against 8 for the Klipsch Groove. It is rated IP67 against IPX4 for the Klipsch Groove. It charges over USB-C rather than Micro USB. The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
The Klipsch Groove is the lighter choice. Pretty balanced sound in a compact, splash-resistant form factor. At 1.7 lbs (770 g) it weighs noticeably less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports AAC Bluetooth, which the Harman Kardon Luna lacks. It keeps a wired aux input, which the Harman Kardon Luna lacks. The tradeoff: Bass doesn’t go as deep as class leaders.
