Short answer: the Marshall Emberton II if sound quality matters most, the Oontz Angle 3 Ultra if price matters most, though neither ranks well in its class. The Marshall Emberton II ranks #127 of 179 medium speakers, rated 2.7/5, at $151.99. The Oontz Angle 3 Ultra ranks #163, rated 2.2/5, at $39.99, $112 cheaper. Both are rated below 3.0/5 among the 179 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Marshall Emberton II is the better-sounding, deeper-bass choice. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. Its bass reaches about 62Hz before falling 10dB, against 90Hz for the Oontz Angle 3 Ultra. It is rated for 30 hours of battery against 20 for the Oontz Angle 3 Ultra. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The Oontz Angle 3 Ultra is the lighter pick. A cheap, very light waterproof speaker with a long battery and plenty of features for the money. At 0.9 lbs (400 g) it weighs much less than the Marshall Emberton II at 1.5 lbs (700 g). It keeps a wired aux input, which the Marshall Emberton II lacks. Watch for: Very little bass with horrible upper bass thud at higher levels.
Buy the Marshall Emberton II if sound quality matters more than the price. Buy the Oontz Angle 3 Ultra if the price matters more than sound quality.
