Short answer: the Motion Boom, despite the higher price. It ranks #14 of 120 large speakers at $109.99. The X10 costs less at $80 but ranks #94 of 113 in the boombox class, near the bottom of a bigger field. The Soundcore Motion Boom is discontinued; its replacement is the Soundcore Boom 2.
The X10’s spec sheet is long: a claimed 42-hour battery, a power bank function, and dual woofers with tweeters and passive radiators. Our notes describe the sound as heavily rolled off in the treble, with less bass than the top-ranked speakers in its class.
The Motion Boom is the more reliable buy on measured sound, called excellent budget-friendly value in our notes, with a genuine 24-hour battery of its own.
Buy the Motion Boom. The extra $29.99 buys a speaker that measures dramatically better within its class.
