Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 113 boombox speakers by sound quality, rated 4.3/5, at $249.95. The W-King X20S ranks #30, rated 3.8/5, at $150.99, $98.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Encore Essential 2 sounds better. Side by side it played louder with better bass and a nicer, richer sound. The X20S was the better value, costing about half as much.
The Encore Essential 2 is well measured, with about 110dB of output, a balanced midrange and punchy low bass. It has wired mic and guitar inputs, a 7-band app EQ and Auracast.
The X20S is IPX7 against the Encore’s IPX4, with FM radio, TF and USB playback, a built-in microphone and a shoulder strap. Its rating comes from listening comparisons, not measurements.
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality, and the $98.96 saving on the W-King X20S is not enough to make up the difference.
There is a real battery-life gap here: the W-King X20S is rated for 24 hours, the JBL Partybox Encore Essential 2 only 15 hours.
