TRUE STEREOPHONIC 360° SOUND
Front and back speakers keep you in the music.
Unleash the energy of live music with our exclusive True Stereophonic 360° technology. Front-and-back speakers creates a sound that feels bigger than the speaker itself. No front row. No back row. A sweet spot wherever you stand.
40+ HOURS OF PORTABLE PLAYTIME
Party the whole day, night and then some.
For the parties that refuse to quit, Bromley 150 keeps the music going. All day, all night, and then some on just one charge. Still not ready to call it a night? Keep a spare battery close. It’s compact, easy to carry and quick to swap, so the music never has to stop.


INTEGRATED STAGE LIGHTS
Pick from 3 presets, inspired by live performances.
Let the lights go as hard as the music. Inspired by the rigs that light up the world’s biggest stages, Bromley 150 brings that same show-stopping energy to your party. Choose from three presets to shift the mood, from subtle ambience to full power. Always adding the live-show magic to every beat.
MIC & INSTRUMENT INPUTS
Sing and play along to the playlist.
Bromley 150 lets you join the set by plugging in your mic or instrument. The two inputs make it easy to surprise the party with an unexpected show, or turn it into a late-night karaoke session. Mic not included.


DIRT & SPLASH RESISTANT
Don’t worry about a bit of dust and water.
Built to go wherever the party takes you, Bromley 150 is ready for beach days, garden gatherings, and late nights in dusty basements alike. Its IP55 rating means it can take dirt and water splashes without a problem.
BUILT-IN HANDLE
A grab-and-go design for keeping the party on the move.
The party doesn’t stay in one place. Neither does Bromley 150. Its built-in handle sits on top of the speaker, making it easy to grab and go. Whether you’re moving it from room to room or taking the party somewhere remote, just pick it up and get the music started.
