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 JBL Partybox Encore Essential ranks #8, rated 4.2/5, at $299.95, $50 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL PartyBox On-The-Go 2 Plus is the longer-running 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 is rated for 15 hours of battery against 6 for the JBL Partybox Encore Essential. The catch: 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.
What the JBL Partybox Encore Essential does well: A compact stereo party speaker with great sound, strong output, and splash resistance for backyard parties. The tradeoff: Bass is limited by its 38Hz specification.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and the $50 you would save on the JBL Partybox Encore Essential does not close the gap.
