Short answer: the Soundcore Motion 300. It ranks #3 of 177 medium speakers by sound quality, rated 4.5/5, at $79.99. The Xiaomi Sound Outdoor ranks #46, rated 3.7/5, at $49.99, $30 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Soundcore Motion 300 is the better-sounding option. A compact stereo speaker with deep bass for its size, hi res Bluetooth and a custom EQ for each position, standing or lying down. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Outdoor. The tradeoff: 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.
The Xiaomi Sound Outdoor is the lighter choice. An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. At 1.3 lbs (597 g) it weighs noticeably less than the Soundcore Motion 300 at 1.7 lbs (772 g). The catch: Bass reach is limited for the cabinet size, with a rated lower limit of 60Hz, and the boosted bass gets somewhat uncontrolled at high levels.
Buy the Soundcore Motion 300. It is rated higher for sound quality, and saving $30 with the Xiaomi Sound Outdoor does not make up for the sound-quality gap.
