Short answer: the Boat Stone 350, if you are buying new. The JBL Flip 5 ranks higher than it (#74 vs #135 of 157 medium speakers, 3.3/5 vs 2.3/5) but is discontinued, so only consider it used; the Boat Stone 350 is still sold new.
The JBL Flip 5 is the better-sounding, deeper-bass option. Compact and light (1.1 lb) with a carry lanyard. Its bass reaches about 59Hz 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. Watch for: Boosted upper bass.
The Boat Stone 350 is the lighter choice. 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 5 at 1.2 lbs (540 g). It keeps a wired aux input, which the JBL Flip 5 lacks. It plays in stereo from a single unit, unlike the JBL Flip 5. The catch: Midrange peaks with rolled-off treble.
Buy the Boat Stone 350, since the JBL Flip 5 is discontinued and only worth hunting down used.
