Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Encore Essential 2 ranks #6 of 76 boombox speakers by sound quality at $259; the Onn XL Wireless Party Speaker ranks #11 of 40 party speakers by sound quality at $249.
Why pick the JBL Partybox Encore Essential 2: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. The tradeoff: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
What the Onn XL Wireless Party Speaker does well: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. Watch for: Sound favors punch and a forward/bright top end over refinement.
Buy the JBL Partybox Encore Essential 2 at $259 if you want a boombox speaker. Buy the Onn XL Wireless Party Speaker at $249 if you want a party speaker instead.

The Two Speakers In Full
JBL Partybox Encore Essential 2: $259.00 Amazon B&H Photo Video eBay
Older model: the JBL Partybox Encore Essential (rated 4.2/5).
Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior.
Cons: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

Onn XL Wireless Party Speaker: $249.00 Walmart eBay
Pros: A compelling all-in-one party and karaoke package: dual 8-inch woofers, 240W claimed output, two included wireless microphones, dual mic/guitar inputs, karaoke effects and USB-A phone charging. It plays loudly enough for backyard use and has punchy bass; owners especially like the wheels, telescoping handle and colorful light effects. At 44 lb it is still a substantial cabinet, but the trolley design makes moving it far easier than carrying it.
Cons: Sound favors punch and a forward/bright top end over refinement. Independent comparisons and owner reports find the bass less deep and the overall balance less satisfying than the JBL PartyBox 320; several consider the far-cheaper Onn Large Party gen 2 the better sound-per-dollar buy. Some owners report distortion or static at high volume, and a few report wireless-mic pairing/dropout problems. Large (30 inches tall, 44 lb) and only IPX4 splash-resistant, not a speaker to leave out in rain.
