These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Luna 2 ranks #25 of 179 medium speakers by sound quality at $199.95; the Marshall Willen II ranks #11 of 62 small speakers by sound quality at $129.99.
What the Harman Kardon Luna 2 does well: 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.
The Marshall Willen II is the longer-running, lighter option. A tiny waterproof strap on speaker with balanced sound, a long battery, and app EQ that clips easily onto a bag. It is rated for 17 hours of battery against 12 for the Harman Kardon Luna 2. At 0.8 lbs (360 g) it weighs much less than the Harman Kardon Luna 2 at 1.6 lbs (735 g). The tradeoff: Not that deep of bass.
Buy the Harman Kardon Luna 2 ($199.95) for a medium speaker; the Marshall Willen II ($129.99) suits a small speaker instead.
