Short answer: the JBL Flip 6. It ranks #12 of 157 medium speakers by sound quality (rated 4.2/5); the Boat Stone 350 ranks #135 (rated 2.3/5).
The JBL Flip 6 is the better-sounding, deeper-bass pick. A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. Its bass reaches about 56Hz before falling 10dB, against 87Hz for the Boat Stone 350. It is rated for 12 hours of battery against 6 for the Boat Stone 350. The catch: Some slight upper mids emphasis.
The Boat Stone 350 is the lighter option. 10W cylindrical stereo speaker with dual passive radiators, IPX7 water resistance, microSD card slot, and 3.5mm aux input. At 0.9 lbs (426 g) it weighs noticeably less than the JBL Flip 6 at 1.2 lbs (544 g). It keeps a wired aux input, which the JBL Flip 6 lacks. It plays in stereo from a single unit, unlike the JBL Flip 6. Watch for: Midrange peaks with rolled-off treble.
Buy the JBL Flip 6. It is rated higher for sound quality than the Boat Stone 350.
