The Marshall Bromley 750 makes most sense for people who need a loud, rollable party speaker and want wired microphone or instrument inputs—not for buyers seeking a compact speaker for everyday listening. It weighs 23.9 kg, so its wheels and handle help with moving it but do not make it easy to lift or store. Marshall claims more than 40 hours of playtime; its large-room volume and extensive connections are useful, but its premium local price and substantial footprint are real trade-offs.
What kind of speaker is the Bromley 750?
Marshall describes the Bromley 750 as a portable party speaker with “True Stereophonic 360° sound.” That is the manufacturer’s positioning, not an independent listening result. Released in 2025, it is designed around loud-room playback, battery operation and connections for more than a phone. Marshall’s product listing gives dimensions of 652 × 413 × 355 mm and a weight of 23.9 kg. Integrated wheels and a handle make it rollable; carrying it up stairs, putting it in a car, or finding storage still takes planning. Marshall’s support page identifies the model as released in 2025.

How loud is the Marshall Bromley 750?
RTINGS describes the Bromley 750 as a large battery-powered party speaker and reports that its tested unit gets loud enough to fill large rooms. That is a useful independent review finding, not a guarantee for every room, placement or event. Room shape, crowd noise and where the speaker is positioned all affect perceived coverage.

- Bluetooth 5.3, Auracast, multipoint connectivity, and SBC, AAC and LC3 codecs.
- 3.5 mm AUX input and output, RCA, and USB-C.
- Two XLR/6.35 mm combo jacks for microphones or instruments.

How long does the battery last, and how does it charge?
Marshall claims 40+ hours of portable playtime, 5 hours of play from a 20-minute charge, and 3.5 hours for a full recharge. These are manufacturer figures, not independent runtime results. Actual playtime depends on use; Marshall notes that the integrated lights consume significant battery power and that turning them off can extend playback.

What are the main buying trade-offs?
| What may suit you | What to weigh |
|---|---|
| Large-room party playback; RTINGS reports its tested unit can get loud enough to fill large rooms. | Room-filling output is not the same as easy portability: the speaker weighs 23.9 kg and needs space for storage and transport. |
| Two XLR/6.35 mm combo inputs for microphone or instrument use, plus AUX, RCA and USB-C. | Buyers who only stream music from a phone may not need the extra wired inputs; required cables or a microphone are not listed in the box contents. |
| Marshall claims 40+ hours of playback and offers integrated wheels and a handle. | Runtime is usage-dependent, and Marshall says lighting reduces it; the wheels help rolling rather than lifting. |
| Manufacturer-listed IP54 dirt and splash resistance. | It is not an immersion rating or a claim that the speaker is waterproof. |
TechRadar’s review and buying-guide coverage also characterizes the speaker as large and expensive, while noting its physical controls and connectivity; those are editorial judgments rather than test findings made here. TechRadar’s review.

For moderate-volume indoor listening, occasional music from a phone, or a speaker that must be easy to carry and store, its scale and premium price may be more than you need. The decision is less about a single loudness number than whether you will use the room-filling output and live inputs often enough to justify the bulk and cost.
