Short answer: the W-King D320. It ranks #51 of 175 medium speakers by sound quality (rated 3.6/5) at $52.92 and is still sold new; the Zealot S61 ranks #172 (rated 2.0/5) and is discontinued, so it is only an option used.
The W-King D320 is the better-sounding choice. A 3.1 lbs (1.4 kg), IP67-rated travel speaker with claimed 40W output, USB-C charging, aux and microSD playback, speakerphone capability and an app with adjustable EQ. It has an adjustable EQ, which the Zealot S61 lacks. The tradeoff: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
The Zealot S61 is the longer-running, lighter choice. 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 1.5 lbs (665 g) design, single full-range driver, built-in microphone, AUX input, USB-C charging. It is rated for 40 hours of battery against 24 for the W-King D320. At 1.5 lbs (665 g) it weighs much less than the W-King D320 at 3.1 lbs (1.4 kg). The tradeoff: Sounds like a soup can, no bass at all.
Buy the W-King D320. It is rated higher for sound quality and still sold new, while the Zealot S61 is discontinued.

The Two Speakers In Full
W-King D320: $52.92 AliExpress $52.92 eBay
Pros: A 1.4kg, IP67-rated travel speaker with claimed 40W output, USB-C charging, aux and microSD playback, speakerphone capability and an app with adjustable EQ. Owner reports praise its loud, deep-for-size bass and long runtime, while its two tweeters and passive radiators make it a capable choice for casual outdoor listening.
Cons: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air. The claimed 100Hz low-frequency specification suggests that its perceived bass should not be mistaken for true sub-bass; evaluate its tuning with the app rather than expecting a neutral default.
