Short answer: the Soundcore Motion 300. It ranks #2 of 157 medium speakers by sound quality (rated 4.5/5); the Boat Stone 350 ranks #135 (rated 2.3/5).
The Soundcore Motion 300 is the better-sounding, deeper-bass option. Pretty deep bass for the small size. Its bass reaches about 50Hz before falling 10dB, against 87Hz for the Boat Stone 350. It is rated for 13 hours of battery against 6 for the Boat Stone 350. The tradeoff: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings.
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 much less than the Soundcore Motion 300 at 1.7 lbs (772 g). It keeps a wired aux input, which the Soundcore Motion 300 lacks. Watch for: Midrange peaks with rolled-off treble.
Buy the Soundcore Motion 300. It is rated higher for sound quality than the Boat Stone 350.

The Two Speakers In Full
Soundcore Motion 300: $79.99 Amazon eBay
Older model: the Soundcore Motion+ (ranked lower, rated 4.4/5).
Pros: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Measured bass extension of 50Hz (-10dB).
Cons: Without the above EQ or turning the top 2 treble EQ bars to max, this speaker is very rolled off in the treble and will rank around #50 in the rankings. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.
