Soundcore Motion 300 vs Soundcore Boom 3i

Last updated: August 28, 2026

Short answer: the Soundcore Motion 300. It ranks #2 of 136 medium speakers by sound quality at $79.99; the Soundcore Boom 3i ranks #27 and costs $110, so there is not much of a tradeoff to weigh.

What the Soundcore Motion 300 offers: Pretty deep bass for the small size. Pocket size in a big pocket. Can be used in stereo facing you, or omnidirectional lying down. Ability to have a custom EQ for each orientation, standing, lying flat, hanging. Try the Uboom L EQs from Oluv for a more neutral sound. Watch for: 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. Bassup mode is worse than Signature. Not quite as detailed or neutral as higher ranked speakers. Slight bass distortion when turned up.

What the Soundcore Boom 3i offers: Looks to be designed as a direct competitor to the Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the Charge 5. Watch for: Not quite as good as a Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App

Buy the Soundcore Motion 300. It ranks higher for sound quality than the Soundcore Boom 3i and costs less, which settles it without a real tradeoff to make.
