Short answer: the JBL Partybox Encore 2. It ranks #4 of 113 boombox speakers by sound quality, rated 4.4/5, at $330. The W-King X20S ranks #30, rated 3.8/5, at $150.99, $179.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Partybox Encore 2 is the better-sounding option. A compact karaoke party speaker with two wireless mics, better balanced sound than the original and a long battery. The tradeoff: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
The W-King X20S is the longer-running, tougher option. A lighter, waterproof boombox with clear mids, plenty of volume, FM radio and a handle plus shoulder strap. It is rated for 24 hours of battery against 15 for the JBL Partybox Encore 2. It is rated IPX7 against IPX4 for the JBL Partybox Encore 2. The tradeoff: Less bass and depth than the W-King X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass.
Buy the JBL Partybox Encore 2. It is rated higher for sound quality, and the $179.01 saving on the W-King X20S is not enough to make up the difference.
