Short answer: the Harman Kardon Luna on measured sound quality, the Ultimate Ears Roll 2 on price. The Harman Kardon Luna ranks #22 of 136 medium speakers at $290.99. The Ultimate Ears Roll 2 ranks #125 at $100, $190.99 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 Roll 2 offers: Thin, flat profile fits easily in a bag or purse; light at 0.73 lb. Built-in bungee cord for hanging from a hook, nail, or door handle. Life-resistant waterproof/dustproof shell. Watch for: Not stereo. Barely any bass, rolled off treble off axis
Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the Ultimate Ears Roll 2 when the price outweighs sound quality instead.
The Ultimate Ears Roll 2 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
