Short answer: the Marshall Emberton III if sound quality matters most, the DOSS E-Go II if price matters most, though neither ranks well in its class. The Marshall Emberton III ranks #126 of 179 medium speakers, rated 2.7/5, at $179.99. The DOSS E-Go II ranks #148, rated 2.5/5, at $39.90, $140.09 cheaper. Both are rated below 3.0/5 among the 179 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Marshall Emberton III is the deeper-bass, longer-running pick. A tough waterproof speaker with Marshall styling and a very long battery, plus quick charging. Its bass reaches about 62Hz before falling 10dB, against 120Hz for the DOSS E-Go II. It is rated for 32 hours of battery against 12 for the DOSS E-Go II. It has an adjustable EQ, which the DOSS E-Go II lacks. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
The DOSS E-Go II is the lighter pick. A water bottle sized stereo speaker with water resistance and quick pairing, light enough for a cup holder or bag. At 0.9 lbs (399 g) it weighs much less than the Marshall Emberton III at 1.5 lbs (673 g). It keeps a wired aux input, which the Marshall Emberton III lacks. The catch: Horribly bad unless turned up, still not great.
Buy the Marshall Emberton III if sound quality is the priority over the price, or the DOSS E-Go II if the price is the priority over sound quality.
