Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 113 boombox speakers by sound quality, rated 4.4/5, at $349.95. The W-King X20 ranks #43, rated 3.5/5, at $229.99, $119.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL PartyBox On-The-Go 2 Plus is the better-sounding option. A well balanced karaoke party speaker with clean bass, clear vocals, on-board vocal removal, an included wireless mic and a removable battery. It links with other speakers (Auracast), which the W-King X20 cannot. Watch for: The bass has less kick and physical impact than the JBL Partybox Encore 2 or JBL Partybox Club 120, and the JBL Partybox Club 120 gets noticeably louder.
The W-King X20 is the longer-running, tougher pick. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated for 24 hours of battery against 15 for the JBL PartyBox On-The-Go 2 Plus. It is rated IPX6 against IPX4 for the JBL PartyBox On-The-Go 2 Plus. Watch for: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and saving $119.96 with the W-King X20 does not make up for the sound-quality gap.
