What the Onn XL Wireless Party Speaker offers: An exceptional value in a party speaker. Includes 2 wireless microphones. Wheels and a built-in handle for easy transport. 5 multicolor LED lighting effects. Control display on the unit. Watch for: A little bright up top, not quite as well balanced as the JBL Partybox 330.
What the JBL Partybox 300 offers: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Watch for: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead.
Buy the Onn XL Wireless Party Speaker when the price outweighs sound quality for you, and the JBL Partybox 300 when sound quality outweighs the price instead.
There is a real gap in water resistance: the Onn XL Wireless Party Speaker at IPX4 (splashing) against the JBL Partybox 300, which has no water resistance.
