These sit in different size classes, so this is not a straight ranking comparison. The JBL Partybox Encore 2 ranks #4 of 113 boombox speakers by sound quality at $330; the Onn XL Wireless Party Speaker ranks #11 of 53 party speakers by sound quality at $249.
Both include two wireless microphones, but at very different sizes. The Encore 2 is a 14.1 lbs (6.4 kg) boombox. The Onn XL is a 44.1 lbs (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.
