Short answer: the Zealot PT21 unless you want the Sony’s 360-degree effect. The XP700 uses dual 6.69” woofers and X-Balanced Speaker Units with a rear tweeter for a 360 effect, but it has a weird midrange peak. The PT21 serves up 200W and dual 166mm woofers with a bundled wireless mic and echo, and it is the cheaper of the two at $225.86 against $314.95.
Buy the Zealot PT21. It is rated higher for sound quality, and the Sony SRS-XP700 is discontinued, so it is only available used.
Battery life favors the Zealot PT21: rated for 60 hours against 25 hours for the Sony SRS-XP700.
There is a real gap in water resistance: the Zealot PT21 at IPX5 (water jets) against the Sony SRS-XP700, which has no water resistance.

The Two Speakers In Full
Zealot PT21: $225.86 AliExpress eBay
Pros: Dual 166mm woofers and 200W output in a lighter, more compact body than the ZE41, with a bundled wireless microphone and echo effect built in for karaoke. Quite deep bass for the price, even deeper than the JBL Boombox 4 in direct comparisons.
Cons: Unlike some other Zealot models, app-based EQ customization doesn’t appear to be fully supported yet, and IPX5 means it can handle splashes but not submersion.
