Short answer: the JBL Flip 6. It ranks #13 of 182 medium speakers by sound quality, rated 4.2/5, at $114.95. The DBSONO X-Blast F37 ranks #118, rated 2.8/5, at $69.99, $44.96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Flip 6 is the better-sounding, longer-running pick. A small, rugged speaker with very neutral sound for its size, an excellent choice for most people. It is rated for 12 hours of battery against 8 for the DBSONO X-Blast F37. At 1.2 lbs (544 g) it weighs noticeably less than the DBSONO X-Blast F37 at 1.7 lbs (771 g). It is rated IP67 against IPX5 for the DBSONO X-Blast F37. The tradeoff: Some slight upper mids emphasis.
The DBSONO X-Blast F37 is the deeper-bass option. 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 56Hz for the JBL Flip 6. Watch for: Very recessed lower mids, peaky upper mids, just not a great frequency response overall.
Buy the JBL Flip 6. It is rated higher for sound quality, and the $44.96 saving on the DBSONO X-Blast F37 is not enough to make up the difference.
