Short answer: the Harman Kardon Luna for better sound quality, the Marshall Emberton II for the lower price. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Marshall Emberton II ranks #100 at $160.23, $130.76 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 Marshall Emberton II offers: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud.
Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the Marshall Emberton II when the price outweighs sound quality instead.
If battery life is a priority, the Marshall Emberton II is rated for 30 hours versus 12 hours for the Harman Kardon Luna.
