Short answer: the Marshall Bromley 450 on measured sound quality, the Onn Large Party gen 1 on price. The Marshall Bromley 450 ranks #23 of 43 party speakers, rated 3.7/5, at $649.95. The Onn Large Party gen 1 ranks #32, rated 2.7/5, at $100, $549.95 cheaper.
The case for the Marshall Bromley 450: A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. Watch for: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed.
Why pick the Onn Large Party gen 1: A genuinely useful feature set for a compact party speaker: FM radio, 3.5mm aux, USB-A phone charging, a mic/guitar input, lights, and Party Sync pairing. The catch: Sound is not a strong reason to seek one out.
One note: the Onn Large Party gen 1 is no longer in production and isn’t widely stocked new anymore.
Buy the Marshall Bromley 450 if sound quality matters more than the price. Buy the Onn Large Party gen 1 if the price matters more than sound quality.
Battery life favors the Marshall Bromley 450: rated for 40 hours against 13 hours for the Onn Large Party gen 1.

Marshall Bromley 450: $649.95 Amazon B&H Photo Video eBay
Pros: A balanced, warm sound with a flat midrange that keeps vocals and instruments clear, plenty of bass rumble and enough treble for energetic vocals, per RTINGS’ lab tests. Drivers on all four sides keep the tonal balance nearly the same from any angle, and M1M Tech Channel found it more open and airy than the Soundboks Mix and Teufel Rockster Air 2, with deeper bass than both. RTINGS measured 18.8 hours of battery from a swappable LiFePO4 pack shared with the Bromley 750, and it adds IP55 protection, two XLR/6.35mm combo inputs, USB-C audio, Auracast and physical bass and treble knobs.
Cons: It is the quietest of its rivals: both the Soundboks Mix and Teufel Rockster Air 2 play louder, and near max volume the bass recedes and the sound gets less composed. The warm tuning lacks some fine treble detail. There is no graphic EQ, only bass and treble knobs, and its stereo spreads left and right channels around the cabinet, so panned elements can land on the wrong side. At 12.3 kg it has a carry handle but no wheels.

Onn Large Party gen 1: $100 Discontinued eBay
Newer model: the Onn Large Party gen 2, ranked higher, rated 3.9/5.
Pros: A genuinely useful feature set for a compact party speaker: FM radio, 3.5mm aux, USB-A phone charging, a mic/guitar input, lights, and Party Sync pairing. Its rolling 10.5kg cabinet, carry handle and claimed 13-hour battery make it easy to take to casual outdoor gatherings, and it can play louder than a typical small Bluetooth speaker. Measured bass extension of ~60Hz (-10dB).
Cons: Sound is not a strong reason to seek one out. Reviewer comparisons find limited deep bass (about 60Hz at -10dB), uneven mids and a boxy, strained presentation at high volume. It has no app or EQ, no water rating, and is discontinued; the newer Onn Large Party gen 2 is the more sensible choice when available.
