Short answer: the Monster Rockin’ Roller 270 for battery life, the Yeahbox Sonic Boom Max 3 for driver hardware. The Monster runs a 100 hour battery but its bass is not as deep as competitors and it is less neutral than ION speakers. The Yeahbox claims 200W RMS (300W peak) from a true 3-way, 5-driver array, though it is a budget brand with limited independent testing and manufacturer-claimed specs.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality, and the $20 you would save on the Monster Rockin’ Roller 270 does not close the gap.
