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 EcoXGear Defender ranks #72, rated 2.5/5, at $299.99, $49.96 cheaper, a saving that is not big enough to make up 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 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 case for the EcoXGear Defender: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. The catch: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and the $49.96 saving on the EcoXGear Defender is not enough to make up the difference.
Battery life favors the EcoXGear Defender: rated for 25 hours against 15 hours for the JBL PartyBox On-The-Go 2 Plus.
If water resistance matters to you, the EcoXGear Defender at IP67 (brief submersion) holds up far better than the JBL PartyBox On-The-Go 2 Plus at IPX4 (splashing).

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.

EcoXGear Defender: $299.99 Amazon eBay
Pros: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode.
Cons: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited. The default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode. Bass does not reach as deep as competitors.
