Short answer: the Harman Kardon Luna for better sound quality, the Ultimate Ears Wonderboom for the lower price. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Ultimate Ears Wonderboom ranks #87 at $79, $211.99 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 Ultimate Ears Wonderboom offers: IP67 rated and floats. Compact, light, and simple to use. Watch for: Not stereo, barely any bass, recessed treble. Dip at 9khz. Low mid bass distortion. Not technically a 360 speaker, only front and rear.
Buy the Harman Kardon Luna if sound quality is the priority over the price, or the Ultimate Ears Wonderboom if the price is the priority over sound quality.
