Short answer: the JBL Grip. It ranks #89 of 157 medium speakers by sound quality (rated 3.1/5); the Boat Stone 350 ranks #135 (rated 2.3/5).
The JBL Grip is the better-sounding, deeper-bass choice. Ambient light on the back with settable themes. Its bass reaches about 68Hz before falling 10dB, against 87Hz for the Boat Stone 350. It is rated for 14 hours of battery against 6 for the Boat Stone 350. The tradeoff: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip.
Why pick the Boat Stone 350: 10W cylindrical stereo speaker with dual passive radiators, IPX7 water resistance, microSD card slot, and 3.5mm aux input. It keeps a wired aux input, which the JBL Grip lacks. It plays in stereo from a single unit, unlike the JBL Grip. Watch for: Midrange peaks with rolled-off treble.
Buy the JBL Grip. It is rated higher for sound quality than the Boat Stone 350.

JBL Grip: $99.95 Amazon B&H Photo Video eBay
Pros: Ambient light on the back with settable themes. Measured bass extension of ~68Hz (-10dB).
Cons: Lacking deeper bass, definitely the worst of the JBL line until you get to the smaller clip. Not as much clarity as higher ranked speakers, rolled off highs and wavy midrange
Setup: EQ from Oluv in his post can help it a bit but still isn’t very neutral
