Short answer: the Soundcore Motion 300. It ranks #2 of 134 medium speakers at $79.99; the Sony ULT Field 1 ranks #75 and costs $138, so there is not much of a tradeoff to weigh.
What the Sony ULT Field 1 gets right: IP67 rated, survives drops and 1m submersion. The tradeoff: Upper midrange peak, rolled off treble.
On the Soundcore Motion 300 side: Pretty deep bass for the small size. Set against that: Without the above EQ or turning the top 2 treble EQ bars to max.
Buy the Sony ULT Field 1 if the price matters more than the ranking. Buy the Soundcore Motion 300 if the ranking matters more than the price.

Soundcore Motion 300: $79.99 Amazon
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.
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.
