Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 89 boombox speakers by sound quality, rated 4.4/5, at $349.95. The JBL Partybox Encore Essential ranks #8, rated 4.2/5, at $329.95, $20 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the JBL PartyBox On-The-Go 2 Plus does well: Well balanced with strong vocals, and its front-firing bass ports give it cleaner, smoother bass than other PartyBoxes, so even the Punchy bass boost setting never overpowers the vocals. The tradeoff: The bass has less kick and physical impact than the Encore 2 or PartyBox Club 120, and the Club 120 gets noticeably louder.
What the JBL Partybox Encore Essential does well: JBL Partybox Encore Essential uses 135mm woofer + 2x 44mm tweeters. 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 $20 you would save on the JBL Partybox Encore Essential does not close the gap.
Battery life favors the JBL PartyBox On-The-Go 2 Plus: rated for 15 hours against 6 hours for the JBL Partybox Encore Essential.

The Two Speakers In Full
JBL PartyBox On-The-Go 2 Plus: $349.95 Amazon eBay
Older model: the JBL Partybox On the Go (ranked lower, rated 3/5).
Pros: Well balanced with strong vocals, and its front-firing bass ports give it cleaner, smoother bass than other PartyBoxes, so even the Punchy bass boost setting never overpowers the vocals. It gets a touch louder than the PartyBox Encore 2. EasySing AI vocal removal strips vocals from any song on the speaker itself, with 25%, 50% or 100% removal, and the included rechargeable wireless mic has a tight pickup pattern that rejects handling noise. A removable 34Wh battery shared with the Encore 2 and PartyBox 120, a claimed 15 hours, a padded shoulder strap, USB-C playback and charging, a 3.5mm aux input, Auracast and a light show.
Cons: The bass has less kick and physical impact than the Encore 2 or PartyBox Club 120, and the Club 120 gets noticeably louder. There is no wired microphone or guitar input, so more mics means buying JBL’s EasySing mics separately, and AI vocal removal is disabled while the speaker is linked to other speakers over Auracast. Real world battery life is closer to 7 hours at 80% volume with lights and bass boost on. IPX4 only covers splashes, the grille dents easily, and the battery must be installed for it to run even when plugged in.
