Short answer: the Tronsmart Halo 300. It ranks #18 of 44 party speakers by sound quality (rated 3.9/5); the Marshall Bromley 450 ranks #24 (rated 3.7/5).
Why pick the Tronsmart Halo 300: A 240W party speaker with a 2.2 channel three-way layout (dual woofers, mid-tweeters and tweeters) angled for a 270° soundstage. Watch for: The W-King T12 reaches deeper with thicker bass.
The Marshall Bromley 450 is the longer-running choice. 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. It is rated for 40 hours of battery against 20 for the Tronsmart Halo 300. 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.
Buy the Tronsmart Halo 300. It is rated higher for sound quality than the Marshall Bromley 450.

The Two Speakers In Full
Tronsmart Halo 300 eBay
Pros: A 240W party speaker with a 2.2 channel three-way layout (dual woofers, mid-tweeters and tweeters) angled for a 270° soundstage. Side by side with the W-King T12 it sounded cleaner and more accurate, with instruments and vocals easier to pick out and good kick bass, and listeners report no distortion at any volume. Wheels and a handle, mic, guitar and XLR inputs, lights and a claimed 20 hours of battery.
Cons: The W-King T12 reaches deeper with thicker bass. On battery the Halo’s bass holds back from what its woofers could do, though plugged into AC power it gains noticeably more. It is currently out of stock at Tronsmart in the US.

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.
