Short answer: the Soundcore Boom 2 Plus. It ranks #39 of 113 boombox speakers by sound quality, rated 3.6/5, at $169.99; the Monster Rockin’ Roller 270 ranks #104, rated 2.1/5, and costs $208.99, so there is little reason to consider the other one.
The Soundcore Boom 2 Plus is the better-sounding, deeper-bass option. A fairly light stereo boombox, easy to carry to the beach or park. Its bass reaches about 39Hz before falling 10dB, against 53Hz for the Monster Rockin’ Roller 270. At 8.4 lbs (3.8 kg) it weighs much less than the Monster Rockin’ Roller 270 at 28.7 lbs (13 kg). It is rated IPX7 against IPX4 for the Monster Rockin’ Roller 270. The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
The Monster Rockin’ Roller 270 is the longer-running pick. A wheeled party speaker with an enormous battery, sound spread wide around it and a wireless phone charging pad. It is rated for 100 hours of battery against 20 for the Soundcore Boom 2 Plus. Watch for: Bass not as deep as competitors, less neutral than ION speakers.
Buy the Soundcore Boom 2 Plus. It is rated higher for sound quality than the Monster Rockin’ Roller 270 and costs less, so only choose the other one for a particular feature it does better.
