These are not really the same size class, and that is the honest framing here. The Boat Stone 193 ranks #38 of 54 small speakers by sound quality; the Boat Stone 350 ranks #142 of 164 medium speakers by sound quality. Both are rated below 3.0/5 for their class (54 small speakers and 164 medium speakers), so if sound quality matters, look higher up the rankings.
The Boat Stone 193 is the lighter pick. Cosmetic variant of the Stone 190 with identical 52mm driver and IPX7 waterproof casing. At 0.4 lbs (185 g) it weighs much less than the Boat Stone 350 at 0.9 lbs (426 g). The tradeoff: Low bass rolls off sharply below 95Hz.
What the Boat Stone 350 does well: 10W cylindrical stereo speaker with dual passive radiators, IPX7 water resistance, microSD card slot, and 3.5mm aux input. It has an adjustable EQ, which the Boat Stone 193 lacks. It plays in stereo from a single unit, unlike the Boat Stone 193. Watch for: Midrange peaks with rolled-off treble.
Buy the Boat Stone 193 for a small speaker; the Boat Stone 350 suits a medium speaker instead.
