Short answer: the Soundcore Motion X500 for stereo sound, the Ultimate Ears Boom 3 for a tougher floating design and PartyUp. The X500 delivers 40W of stereo from a three-driver layout with an IPX7 rating and battery life close to its 12-hour claim, though it is a little bright on top with a peak at 250Hz and a dip at 1kHz. The Boom 3 has a strong 15-hour battery and an IP67 floating shell.
Buy the Ultimate Ears Boom 3 ($132.99) for a medium speaker; the Soundcore Motion X500 ($99.99) suits a large speaker instead.
