Short answer: the JBL Partybox 310 for sound quality, the Onn XL Wireless Party Speaker if budget is the deciding factor. These rank #4 and #11 out of 53 party speakers, for a price difference of $330.95. The JBL Partybox 310 is discontinued; its replacement is the JBL Partybox 330. If you are buying new, get the JBL Partybox 330.
The 310’s bass is genuinely exceptional. Our notes describe it as having the absolute deepest bass of any battery-powered speaker, measured at 32Hz extension, along with the most balanced sound in its class and performance very close to the newer 320. Its practical downsides are size (it’s very large) and JBL’s daisychain party linking not working with non-JBL speakers, not anything about how it sounds.
The Onn XL earns its price with real included extras. It ships with two wireless microphones in the box, has 5 multicolor LED lighting effects and an onboard control display, and our notes call it an exceptional value for a party speaker. The tradeoff is tonal: it’s described as a little bright up top and not as well balanced as JBL’s own Partybox 330.
Everything else matches: both have wheels and a built-in handle, IPX4 splash resistance, guitar input, karaoke-mode microphone input, and a USB-A power bank output.
Buy the JBL Partybox 310 for the deepest bass and most balanced sound of the two, especially if you don’t mind its size.
Buy the Onn XL Wireless Party Speaker if two included wireless microphones and a lower price matter more to you than the last word in bass depth and tonal balance.
