Short answer: the Marshall Stockwell II, with the Everboom’s data still thin. The Everboom has little data so its ranking may shift, and it carries an upper bass boost with a warm, rolled-off treble and bass that does not dig deep. The Stockwell II is possibly the most natural Marshall speaker with excellent off-axis performance, though it is not stereo, is not very loud and adds a DSP reverb some may find annoying.
Buy the Marshall Stockwell II. It is rated higher for sound quality, and the $80 saving on the Ultimate Ears Everboom is not enough to make up the difference.
Water resistance is not close: the Ultimate Ears Everboom is rated at IP67 (brief submersion), well ahead of the Marshall Stockwell II at IPX4 (splashing).
