The Marshall Bromley 750 makes the most sense if you need a party speaker that can fill a large room and accept wired microphones or instruments. Its trade-off is substantial: at 23.9 kg, it is a large speaker to store, lift, or load into a vehicle, even with its wheels and handle. For everyday listening at moderate volume, many buyers may not need its size or live-input flexibility.
What is the Marshall 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. Marshall’s support page says the model was released in 2025. Its dimensions are 652 × 413 × 355 mm, and its listed unit weight is 23.9 kg. Integrated wheels and a handle help move it across suitable surfaces, but do not make it a lightweight speaker to carry or store.
Marshall’s product listing showed a starting price of $1,299.99 on the regional listing accessed in 2026. That figure is not a universal price: check Marshall’s listing for your market because price and stock can vary by region and over time. Marshall Bromley 750 product page · Marshall support page
How does it sound, and how loud is it?
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 useful independent review evidence, but it is not a guarantee for every room: results depend on room size, layout, placement, and listening conditions. RTINGS also notes its extensive wired connectivity, including XLR inputs and daisy chaining. RTINGS’ Bromley 750 review
#1 Best Overall
- TRUE STEREOPHONIC: Crystal-clear 360° sound.
- 40+ HOURS OF PORTABLE PLAYTIME: Keep playing all day and through to the next night.
- SOUND CHARACTER CONTROL: Match the music to the pace of your party. Go from pre-party mingling to the peak and then straight to the after-party with a few simple adjustments.
- INTEGRATED STAGE LIGHTS: Pick from three stage-inspired presets.
- MIC & INSTRUMENT INPUTS: Bromley 750 has been designed with all the inputs you need to connect mics, instruments, and turntables for the ultimate party.
Marshall’s own maximum sound-pressure-level figures do not agree. Its product specification lists 127 dB at 1 m, while its support FAQ says “up to 128 dB.” Neither figure is an independent measurement here, so treat both as manufacturer claims rather than a verified result. Marshall product specifications · Marshall support FAQ
What can you connect to it?
The Bromley 750 is more flexible than a Bluetooth-only party speaker. Marshall lists Bluetooth 5.3 with Auracast, Bluetooth multipoint, and SBC, AAC, and LC3 codecs. Wired connections include a 3.5 mm AUX input and output, USB-C, RCA, and two XLR/6.35 mm combo jacks for microphones or instruments. Check your source device’s output and cable requirements before buying accessories.
Rank #2
- TRUE STEREOPHONIC 360° SOUND: Drivers on all sides so you can feel the beat no matter where you're standing.
- 40+ HOURS OF PORTABLE PLAYTIME: More than enough for your 800-track setlist.
- INTEGRATED STAGE LIGHTS: 3 presets to light up the dancefloor.
- MIC & INSTRUMENT INPUTS: Sing or play along to your favorite music. Microphones not included.
- DIRT & SPLASH RESISTANT (IP55): Ready for parties indoors and out.
Marshall’s box contents list the speaker with its battery installed, a mains lead, a quick start guide, and a legal/safety sheet; they do not list a microphone. If you plan to use the combo inputs, budget for a compatible wired microphone or instrument cable as needed. No particular accessory has been tested or endorsed here.

At 23.9 kg, the Bromley 750 is portable mainly in the sense that it can be rolled using its integrated wheels and handle. Consider the full route from storage to listening space: stairs, thresholds, vehicle loading, and where the speaker will live between events. If you regularly need to lift a speaker alone, its weight may matter more than its portability label.

How long does the battery last?
Marshall claims 40+ hours of portable playtime. Actual runtime depends on use; Marshall notes that the integrated lights consume significant battery power and that switching them off can extend playtime. The company also claims that 20 minutes of charging provides five hours of playtime, and that a full recharge takes 3.5 hours. These are manufacturer figures, not independently measured results. Marshall product page · Marshall support page
Can you use it outdoors?
Marshall lists an IP54 rating and describes the speaker as dirt and splash resistant. That is protection against some dust and splashes, not immersion protection; do not treat the Bromley 750 as waterproof or leave it exposed to conditions beyond its rating. Marshall product specifications

Can the battery or speaker be repaired?
Marshall marks the battery rechargeable, replaceable, and exchangeable, and its support page links to spare-part instructions and repair information. That supports a cautious conclusion that service and battery replacement are contemplated, but it does not establish that a specific part is in stock or that repair is available at a particular price. Check with Marshall for regional part availability, service eligibility, and costs. Marshall product information · Marshall repair and support information

Who should buy the Bromley 750?
- A strong fit: hosts who want loud-room coverage, long claimed battery life, and the option to connect wired microphones or instruments.
- Consider a smaller speaker: if you mostly listen indoors at moderate volume, do not need live inputs, or have limited storage and lifting capacity.
- Check before buying: the current price and stock in your region, the cables your equipment needs, and whether you can move and store a 23.9 kg speaker comfortably.
TechRadar’s coverage also characterizes the Bromley 750 as a large, expensive party speaker and highlights its physical controls and connectivity; those are editorial judgments rather than firsthand findings in this review. TechRadar Bromley 750 coverage
