Short answer: the EarFun Uboom L, since the Motion+ is discontinued. The Uboom L pairs IP67 protection with a convincing stereo image when two units are linked, though it cannot produce real low-bass rumble and loses top-end detail at volume. The Motion+ uses separate tweeters and bigger woofers for more bass at full volume and better off-axis treble, but Soundcore has discontinued it and it needs a community EQ profile. The Soundcore Motion+ is discontinued; its replacement is the Soundcore Motion 300.
Uboom L pairs IP67 protection with indoor/outdoor sound modes and a genuinely convincing stereo image when two units are linked, though it can’t produce real low-bass rumble and the top end loses some detail at volume.
Motion+ uses separate tweeters and bigger woofers for more bass at full volume and better off-axis treble per our own notes, but Soundcore has discontinued it and it needs a community EQ profile to get there.
Buy the EarFun Uboom L for the stronger value and the fact that it’s still sold new. Buy the Motion+ only if you find old stock and are willing to install the EQ profile it needs to sound its best.
