Short answer: the Soundcore Motion Boom offers far more output, bass and outdoor utility, while the Marshall Stockwell 2 is the smaller speaker with an aux input and a more refined portable form. Stockwell has a 20-hour claimed battery, a compact 1.4kg body and a 44Hz bass specification, but no app or EQ and only IPX4 protection.
The Motion Boom costs $109.99, reaches a claimed 106dB, has stereo drivers, BassUp, app EQ, 24-hour claimed battery, USB power bank output and a buoyant IPX7 cabinet. It is not as neutral or detailed as the best portable speakers, but it is built for much more scale than Stockwell.
Choose Stockwell for small-room listening and aux sources. Choose Motion Boom if you actually want a loud, weather-resistant outdoor speaker.
Buy the Marshall Stockwell 2 if compact size, aux input and its distinctive portable design matter more than volume.
Buy the Soundcore Motion Boom if you want louder stereo sound, stronger bass, app EQ and IPX7 outdoor protection.
