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 108 large speakers by sound quality at $99.99; the Soundcore Motion 300 ranks #3 of 173 medium speakers by sound quality at $79.99.
The Soundcore Boom 2 is the louder, longer-running pick. A 3.7 lbs (1.68 kg) IPX7 waterproof speaker with pretty deep bass for its size (47Hz at -10dB), 105dB maximum SPL and 24-hour battery life. Alan Ross Reviews measured it at 105dB at full volume, against 101dB for the Soundcore Motion 300. It is rated for 24 hours of battery against 13 for the Soundcore Motion 300. The tradeoff: Only a single midrange driver, so you only get stereo for the tweeters.
The Soundcore Motion 300 is the lighter choice. A compact 1.7 lbs (772 g) stereo speaker with pretty deep bass for its size, LDAC support and a 9-band EQ you can set for each orientation. At 1.7 lbs (772 g) it weighs much less than the Soundcore Boom 2 at 3.7 lbs (1.68 kg). It supports LDAC Bluetooth, which the Soundcore Boom 2 lacks. The catch: 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.
Buy the Soundcore Boom 2 at $99.99 if you want a large speaker. Buy the Soundcore Motion 300 at $79.99 if you want a medium speaker instead.
