Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 91 boombox speakers by sound quality, rated 4.4/5, at $349.95. The onn Pro X Large Boom Boombox ranks #44, rated 3.4/5, at $199, $150.95 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. 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 catch: The bass has less kick and physical impact than the Encore 2 or PartyBox Club 120, and the Club 120 gets noticeably louder.
The onn Pro X Large Boom Boombox is the longer-running, tougher option. High rated power for the price at 180W RMS (540W peak). It is rated for 20 hours of battery against 15 for the JBL PartyBox On-The-Go 2 Plus. It is rated IP67 against IPX4 for the JBL PartyBox On-The-Go 2 Plus. The tradeoff: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and saving $150.95 with the onn Pro X Large Boom Boombox does not make up for the sound-quality gap.

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.
