Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Boom 2 ranks #10 of 120 large speakers by sound quality at $99.99; the Marshall Emberton II ranks #127 of 179 medium speakers by sound quality at $151.99.
The Soundcore Boom 2 is the louder, deeper-bass choice. A light, waterproof large speaker with deep bass for its size, a 24 hour battery and fun lighting. Its bass reaches about 47Hz before falling 10dB, against 62Hz for the Marshall Emberton II. Alan Ross Reviews measured it at 105dB at full volume, against 88dB for the Marshall Emberton II. Watch for: Only a single midrange driver, so you only get stereo for the tweeters.
The Marshall Emberton II is the lighter pick. A tough waterproof speaker with Marshall styling, a very long battery and quick charging. At 1.5 lbs (700 g) it weighs much less than the Soundcore Boom 2 at 3.7 lbs (1.68 kg). Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
Buy the Soundcore Boom 2 at $99.99 for a large speaker, or the Marshall Emberton II at $151.99 for a medium speaker instead.
