Short answer: the Boat Stone 350, though neither ranks well in its class. It ranks #135 of 157 medium speakers by sound quality (rated 2.3/5); the Doss Soundbox Pro ranks #150 (rated 2.1/5). Both are rated below 3.0/5 among the 157 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.

The Boat Stone 350 is the lighter pick. 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 Doss Soundbox Pro at 1.2 lbs (558 g). It charges over USB-C rather than Micro USB. Watch for: Midrange peaks with rolled-off treble.
The Doss Soundbox Pro is the longer-running pick. 20W output, waterproof (IPX6), excellent battery life (20 hours), extra bass button and LED lights, MicroSD card support, dual woofer drivers. It is rated for 20 hours of battery against 6 for the Boat Stone 350. The catch: Barely any bass.
Buy the Boat Stone 350. It is rated higher for sound quality than the Doss Soundbox Pro.
