Short answer: the W-King X20S. It ranks #30 of 113 boombox speakers by sound quality, rated 3.8/5, at $150.99; the W-King X20 ranks #43, rated 3.5/5, and costs $229.99, which makes this an easy call rather than a real tradeoff.
The X20S is clearer, the X20 hits harder. Side by side, the X20S sounded smoother with more clarity, while the X20 had more bass and depth, played about 3dB louder and kept more bass at max volume. At max, the X20S’s mids and highs start to drown out its bass.
The X20S is about half the size and weight, at 13.8 lbs (6.25 kg), with IPX7 against the X20’s IPX6, Bluetooth 5.4, a built-in microphone and FM radio. The X20 measured about 112dB and claims 24 hours with a power bank.
Evidence: the X20S’s rating comes from listening comparisons, not measurements.
Buy the W-King X20S. It is rated higher for sound quality than the W-King X20 and costs less, so only choose the other one for a particular feature it does better.
