Soundcore Motion 300 vs Ultimate Ears Wonderboom 3

Last updated: August 28, 2026

Short answer: the Soundcore Motion 300 ranks #2 of 136 medium speakers by sound quality at $79.99; the Ultimate Ears Wonderboom 3 ranks #85 at $79.99. The price gap is small enough that the sound-quality ranking should decide it.

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 Ultimate Ears Wonderboom 3 offers: IP67 rated, floats, and is rated to survive a 5 ft drop onto hard surfaces. 14 hour battery - longer than the Wonderboom 2. Watch for: Not stereo, barely any bass. Boosted 93hz upper bass. Cuts bass heavily at high volume. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2022. Not technically a 360 speaker, only front and rear.

Buy the Soundcore Motion 300. It ranks higher for sound quality than the Ultimate Ears Wonderboom 3 at the same price, so the other one has nothing left to offer.
