These are not really the same size class, and that is the honest framing here. The Xiaomi Sound Outdoor ranks #46 of 179 medium speakers by sound quality at $49.99; the Zealot S67 ranks #118 of 120 large speakers by sound quality at $70.94.
The Xiaomi Sound Outdoor is the lighter pick. 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 much less than the Zealot S67 at 5.3 lbs (2.4 kg). It links with other speakers (Speakersync, up to 100 speakers), which the Zealot S67 cannot. The tradeoff: 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.
The Zealot S67 is the longer-running pick. A budget waterproof speaker with a long rated battery, USB-C charging, microSD playback, and stereo pairing. It is rated for 20 hours of battery against 12 for the Xiaomi Sound Outdoor. It keeps a wired aux input, which the Xiaomi Sound Outdoor lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Outdoor. Watch for: Sound quality is the catch.
Buy the Xiaomi Sound Outdoor ($49.99) for a medium speaker; the Zealot S67 ($70.94) suits a large speaker instead.
