Short answer: the W-King D320. It ranks #47 of 150 medium speakers by sound quality, rated 3.6/5, at $52.92; the Tronsmart Mirtune C3 Plus ranks #75, rated 3.3/5, at $49.99. Close enough in price that the sound-quality gap is the deciding factor.
What the W-King D320 does well: 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. The catch: A single D320 is not stereo, and its warm balance trades away some detail and upper-treble air.
Why pick the Tronsmart Mirtune C3 Plus: A racetrack woofer and a tweeter rated for 50W, with IPX7 waterproofing, Bluetooth 6.0, Auracast multi-speaker sync, stereo pairing, USB-C audio input, app EQ and a detachable lanyard, at 0.81 kg. Watch for: In side by side tests by Clinch Audio Bass and Mateusz Cholewa, the Xiaomi Sound Party and Soundcore Boom 3i sounded more refined and fuller, and listeners described the C3 Plus’s treble as dull.
Buy the W-King D320. It is rated higher for sound quality, and saving $2.93 with the Tronsmart Mirtune C3 Plus does not make up for the sound-quality gap.

The Two Speakers In Full
W-King D320: $69.99 AliExpress 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.
