These sit in different size classes, so this is not a straight ranking comparison. The JBL Partybox Encore 2 ranks #4 of 76 boombox speakers by sound quality at $330; the Onn XL Wireless Party Speaker ranks #11 of 40 party speakers by sound quality at $249.
Both include two wireless microphones, but at very different sizes. The Encore 2 is a 6.4 kg boombox. The Onn XL is a 20 kg party tower on wheels. Each is rated within its own class.
The Encore 2 improves on the first Encore with dome tweeters and a less boomy balance, measured about 110dB, and has a 7-band app EQ, Auracast and a removable battery with a claimed 15 hours. It lacks some upper bass punch.
The Onn XL has dual 8 inch woofers, mic and guitar inputs, a telescoping handle and a claimed 16 hours. It is loud with punchy bass, but bright on top, and some owners report distortion or mic pairing problems.
Both are IPX4.
Buy the JBL Partybox Encore 2 at $330 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 2: $330 Sam’s Club eBay
Older model: the JBL Partybox Encore (rated 4.3/5).
Pros: The Encore 2 improves the original with dome tweeters, a less boomy balance, slightly deeper bass, longer battery life and two included wireless microphones. Its compact karaoke-ready design and 7-band EQ make it more adaptable indoors than the earlier Encore.
Cons: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes. The main value is compact karaoke convenience rather than full-range party output.

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.
