The Marshall Bromley 150 Portable Party Speaker: Boosted Sound for Any Event

We all have a favorite song. And there’s nothing worse than struggling to hear it when at a party. Even as you move about the room, it feels as though you have to be directly next to the sound system to hear it properly. With the Marshall Bromley 150 portable speaker, there is no ‘best spot’. Instead, this device makes everywhere feel like the front row. True Stereophonic 360° technology is a brand exclusive, combining front and back speakers to deliver bigger, bolder sound that fills the room. But you aren’t limited to just listening to the musical artists. Join the fun by plugging in a microphone¹, an instrument or both using the two inputs located on the back of the Marshall Bromley 150 speaker.

A Speaker Fit For Any Occasion

If you’re a fan of weekend getaways or multi-day celebrations, the Marshall Bromley 150 speaker is a must-have. Before heading out, charge up the battery to get over 40 hours of playtime. And when you need a little extra power, just 20 minutes of charge time grants an additional five hours. Still need more? We love how easy it is to replace the battery with a spare, meaning the celebration truly doesn’t have to end until you’re ready to call it. However, music isn’t the only way to elevate a party. Try out the Marshall Bromley 150 speaker’s integrated stage lights to transform your venue into a show-stopping scene. Start the night with a gentle ambience before turning up the energy with lights that mimic iconic stages.
