Marshall Bromley 750
Marshall Bromley 750 – Portable 360° Party Speaker
Make every gathering sound bigger. The Marshall Bromley 750 is a powerful, movable party speaker built for music-filled evenings, garden celebrations, live performances and large get-togethers. Its multi-directional speaker system distributes sound around the room, while dedicated sound controls and built-in stage lights help set the mood.
Key highlights: True Stereophonic 360° sound | 40+ hours of playtime | Bluetooth 5.3 with Auracast | Three integrated light-show presets | Two mic/instrument inputs | IP54 protection | Replaceable battery | Handle and wheels.
True Stereophonic 360° Sound
Hear your playlist throughout the party rather than from one sweet spot. Drivers facing different directions—including upward, frontward, rearward and sideways—work together to spread a spacious stereo sound field. The closed cabinet helps deliver controlled bass, and the speaker is designed to perform at both everyday listening and party volumes.
Sound Character Control
Fine-tune the sound for the occasion using the dedicated character control. Choose a more relaxed Dynamic presentation or move toward Loud when the gathering calls for greater impact. Separate bass, treble and volume controls give you hands-on adjustment.
Integrated Stage-Inspired Lights
Bring a visual dimension to your music with integrated lights that react to the soundtrack. Select from three built-in lighting presets or switch the lights off when you prefer a simpler setup or want to conserve battery power.
40+ Hours of Portable Playtime
Enjoy extended listening with a rechargeable, user-replaceable LiFePO4 (LFP) battery. Marshall specifies over 40 hours of playtime under typical test conditions. A 20-minute quick charge can provide approximately 5 hours of music; a full charge takes about 3.5 hours. The speaker can also operate from mains electricity. Real-world battery life depends on sound volume, lighting and usage.
Microphones, Instruments and Live Performance
Two XLR / 6.35 mm combination inputs allow you to connect compatible microphones or instruments. Dedicated input level controls and built-in effects—including reverb and delay—make it useful for announcements, singing sessions, casual performances and music-led events. Microphones and instruments are not listed as included accessories.
Connectivity for Different Setups
Play wirelessly with Bluetooth 5.3 and compatible Auracast features. Bluetooth multipoint supports two connected devices, and the speaker also offers 3.5 mm AUX input/output, RCA audio and USB-C connectivity. Marshall quotes a free-field Bluetooth range of more than 70 metres; walls, interference and connected devices can reduce this range. The Marshall Bluetooth app provides compatible speaker functionality and updates.
Built to Travel Between Events
A retractable pull handle and integrated wheels make moving the speaker more convenient, while side handles help with lifting. The IP54 rating offers protection against dust ingress and splashes, making the speaker suitable for many indoor and outdoor gatherings. It is not waterproof and should not be submerged.
