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 II ranks #127, rated 2.7/5, and costs $151.99, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 179 medium speakers; for better sound, the EarFun Uboom L ranks #2 at $49.79.
The DBSONO X-Blast F37 is the deeper-bass choice. 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 II. Watch for: Very recessed lower mids, peaky upper mids, just not a great frequency response overall.
The Marshall Emberton II is the longer-running, tougher choice. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. It is rated for 30 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 II and costs less, which makes it the one to get unless you need something the other one does better.
