Harman Kardon Luna vs Ultimate Ears Wonderboom 3

Last updated: August 28, 2026

Short answer: the Harman Kardon Luna on measured sound quality, the Ultimate Ears Wonderboom 3 on price. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Ultimate Ears Wonderboom 3 ranks #85 at $79.99, $211 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 3 offers: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery - longer than the Wonderboom 2. Watch for: Not stereo, barely any bass. Boosted 93hz upper bass. Cuts bass heavily at high volume. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2022. Not technically a 360 speaker, only front and rear.

Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the Ultimate Ears Wonderboom 3 when the price outweighs sound quality instead.
