These sit in different size classes, so this is not a straight ranking comparison. The Marshall Willen II ranks #11 of 62 small speakers by sound quality at $129.99; the Marshall Emberton II ranks #127 of 179 medium speakers by sound quality at $151.99.

The Marshall Willen II is the lighter choice. A tiny waterproof strap on speaker with balanced sound, a long battery, and app EQ that clips easily onto a bag. At 0.8 lbs (360 g) it weighs much less than the Marshall Emberton II at 1.5 lbs (700 g). The catch: Not that deep of bass.
The Marshall Emberton II is the deeper-bass, longer-running option. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. Its bass reaches about 62Hz before falling 10dB, against 70Hz for the Marshall Willen II. It is rated for 30 hours of battery against 17 for the Marshall Willen II. It links with other speakers (Marshall Stack), which the Marshall Willen II cannot. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Marshall Willen II ($129.99) for a small speaker; the Marshall Emberton II ($151.99) suits a medium speaker instead.
