The most portable party speaker? Marshall unveils the new compact Bromley 150 with 40 hours of playtime

In terms of inherited features, the compact speaker still comes with two combination instrument or microphone inputs that can be controlled independently, for example. The same goes for the Stage Lights lighting effects, which also help create a proper party atmosphere on the larger models without going overboard with color.

One particularly cool feature is its repairability and easily replaceable battery. The battery is designed to last up to 40 hours, but that's not all. Additional batteries are available as accessories for €99.99, and if you bring several of them to a party, you can turn it into a full festival weekend. The batteries are compatible with all three Bromley models. The corner caps, carrying handle, front grille, controls and battery cover can all be replaced.

Like its larger siblings, the smallest Bromley also features “True Stereophonic 360° technology,” which is designed to distribute sound as evenly as possible in all directions. The placement of the controls is also interesting this time around: They have moved from the front at an angle to the left side, freeing up more space on the front while retaining the tactile controls. There is a carrying strap on top.

For adequate protection in the park and elsewhere, the corners have once again been reinforced, while the Bromley 150 carries an IP55 rating, meaning dust and occasional water splashes won't be a problem.

The Bromley 150 is available to pre-order now at marshall.com, with online availability and sales through select retailers starting October 13. It costs $499.99.
