Marshall Bromley 150 Review: 200W Cube Speaker With 40-Hour Battery

What is the Marshall Bromley 150 and who is it for?

The Marshall Bromley 150 is the smallest cube-shaped party speaker in Marshall's lineup, designed for those who want powerful, portable sound with a premium aesthetic. It suits party hosts, outdoor gatherings, and anyone needing a rugged, great-sounding speaker.

Marshall's Bromley 150 packs a 200W power output into a compact cube cabinet. It features a single woofer and dual full-range drivers, delivering 360-degree sound via Marshall's True Stereophonic technology. The speaker is built for parties but also works as a stylish home statement piece.

Weighing less than its larger siblings and featuring a built-in handle, the Bromley 150 is easy to carry. Its IP55 rating means it can handle dust and water jets, making it suitable for outdoor use. The amp-inspired design with faux-leather and golden details gives it a luxurious look.

For those who want a premium portable speaker, the Bromley 150 is a strong contender.

How does the Marshall Bromley 150 sound?

The Bromley 150 delivers astonishing bass that you can feel, with clear mids and expressive highs. Its 360-degree sound remains impressive from any angle, though vocals in the mid-range lack some texture compared to pricier competitors.

In testing, the Bromley 150 produced deep, controlled bass that extended down to 42Hz. Tracks with heavy sub-bass translated beautifully, with no distortion. Higher-pitched drums and mid-range keys remained clear and well-defined, even at high volumes.

The 360-degree True Stereophonic sound worked well from all sides, outperforming some larger rivals like the Sony ULT Tower 7. However, the speaker lacks LDAC for high-res Bluetooth listening, and some vocal tracks lacked the detail found in other speakers at this price.

For a party speaker, the focus is on impact rather than audiophile insight. The Bromley 150 delivers that impact in spades. If you want a speaker that can also handle movies, pair it with a Gigabyte A16 Pro RTX 5070 Ti laptop for a complete entertainment setup.

What features does the Marshall Bromley 150 offer?

The Bromley 150 includes a 40-hour battery, replaceable parts, Auracast multi-speaker pairing, and mic inputs for karaoke. The stage-light LEDs are classy and can be turned off to save battery. The companion app, however, feels underbaked.

Battery life is a standout: 40 hours on a single charge, and the battery is fully replaceable, extending the speaker's lifespan. Multiple parts are user-replaceable, which is rare in portable speakers.

Auracast connectivity lets you pair multiple speakers for a bigger soundstage, and mic inputs support instruments or karaoke. The lighting modes are stylish and can be disabled. The app, however, lacks polish and advanced EQ options.

If you're looking for a smart home companion, the Bromley 150 is not that. But for pure audio performance, it excels. For a smart display to control your music, consider the Eufy E10 window camera at $79.99 — though it's a security camera, not a speaker.

• 40-hour battery life
• IP55 water and dust resistance
• Auracast multi-speaker pairing
• Mic inputs for karaoke
• Replaceable battery and parts
• Stage-light LEDs with multiple modes

Is the Marshall Bromley 150 worth the price?

At around $500, the Bromley 150 is expensive, but its exceptional sound, premium build, and long battery life justify the cost for serious party hosts. If you want the best portable party speaker and can overlook app issues, it's worth it.

The Bromley 150 competes with other high-end party speakers like the Sony ULT Tower 7 and JBL PartyBox series. While it costs more, its sound quality and luxurious design set it apart. The lack of LDAC and a polished app are drawbacks, but not dealbreakers.

For those who prioritize bass impact and 360-degree audio in a portable package, the Bromley 150 is a top choice. If you need more smart features or a lower price, alternatives exist. But for pure party performance, it delivers.

If you're building a home entertainment system, the Bromley 150 could be the centerpiece. For a budget-friendly laptop to manage your playlist, see the HP $199 Walmart laptop.

Bottom line

The Marshall Bromley 150 is a powerful, stylish cube speaker that excels at parties with its 200W output, deep bass, and 40-hour battery. While the app and lack of LDAC are minor flaws, its premium build and 360-degree sound make it a top choice. If you want the best portable party speaker, consider the Bromley 150.
