Short answer: the DBSONO X-Blast F37, though neither ranks well in its class. It ranks #117 of 179 medium speakers by sound quality, rated 2.8/5, at $69.99; the Marshall Emberton III ranks #126, rated 2.7/5, and costs $179.99, so there is not much of a tradeoff to weigh. 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 DBSONO X-Blast F37 is the deeper-bass pick. An affordable splash resistant speaker with a separate woofer and tweeter, long Bluetooth range and stereo pairing. Its bass reaches about 49Hz before falling 10dB, against 62Hz for the Marshall Emberton III. The tradeoff: Very recessed lower mids, peaky upper mids, just not a great frequency response overall.
The Marshall Emberton III is the longer-running, tougher pick. A tough waterproof speaker with Marshall styling and a very long battery, plus quick charging. It is rated for 32 hours of battery against 8 for the DBSONO X-Blast F37. It is rated IP67 against IPX5 for the DBSONO X-Blast F37. It plays in stereo from a single unit, unlike the DBSONO X-Blast F37. The catch: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the DBSONO X-Blast F37. It is rated higher for sound quality than the Marshall Emberton III and costs less, so only choose the other one for a particular feature it does better.
