Short answer: the Soundcore 2. It ranks #105 of 179 medium speakers by sound quality, rated 3.0/5, at $29.99; the DBSONO X-Blast F37 ranks #117, rated 2.8/5, and costs $69.99, so there is not much of a tradeoff to weigh.
The Soundcore 2 is the longer-running, lighter choice. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 8 for the DBSONO X-Blast F37. At 0.7 lbs (318 g) it weighs much less than the DBSONO X-Blast F37 at 1.7 lbs (771 g). It is rated IPX7 against IPX5 for the DBSONO X-Blast F37. Watch for: Bass is specified only down to 70Hz, so the low end is limited.
Why pick the DBSONO X-Blast F37: An affordable splash resistant speaker with a separate woofer and tweeter, long Bluetooth range and stereo pairing. It has an adjustable EQ, which the Soundcore 2 lacks. It charges over USB-C rather than Micro USB. Watch for: Very recessed lower mids, peaky upper mids, just not a great frequency response overall.
Buy the Soundcore 2. It is rated higher for sound quality than the DBSONO X-Blast F37 and costs less, which makes it the one to get unless you need something the other one does better.
