Short answer: the Harman Kardon Luna 2. It ranks #25 of 177 medium speakers by sound quality, rated 4.1/5, at $199.95. The Marshall Emberton II ranks #126, rated 2.7/5, at $114, $85.95 cheaper, which does not close the gap in sound quality.
The Marshall Emberton II is the longer-running option. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. It is rated for 30 hours of battery against 12 for the Harman Kardon Luna 2. It plays in stereo from a single unit, unlike the Harman Kardon Luna 2. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The Harman Kardon Luna 2 is the better-sounding option. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality, and saving $85.95 with the Marshall Emberton II does not make up for the sound-quality gap.
