When it comes to portable audio in 2024, we're spoiled for choice. Today, we're comparing two compelling options: the Ultimate Ears MEGABOOM 4 ($149.99) and the Marshall Willen II ($119.99). While both speakers aim to deliver quality sound on the go, they take notably different approaches to achieve this goal.
The portable speaker market has evolved significantly over the past few years, with dramatic improvements in battery life, durability, and sound quality. Modern speakers need to balance multiple competing factors: sound quality, portability, durability, and battery life. These devices are no longer just for casual listening - they've become essential tools for everything from backyard parties to beach days to impromptu office meetings.
The MEGABOOM 4 shines in this department, utilizing dual 50mm drivers and two passive radiators (think of these as special speakers that help produce deeper bass without requiring additional power). This configuration allows it to produce impressively deep bass for its size, which is particularly noticeable when playing electronic music or hip-hop.
The Willen II, while more limited in bass response due to its smaller size, compensates with surprisingly clear mids and highs. Its single 2-inch driver and dual passive radiators produce clean, detailed sound that works especially well for acoustic music, podcasts, and vocal-heavy content.
Here's where the size difference really matters. The MEGABOOM 4's 91 dBC output might not sound much louder than the Willen II's 88 dB on paper, but the way it distributes sound makes a huge difference. The MEGABOOM 4's 360-degree sound design means it can effectively fill a room or outdoor space from any position. The Willen II, with its directional design, needs more careful placement to achieve optimal sound coverage.
The size difference between these speakers creates two distinct use cases. The MEGABOOM 4 (225mm tall, 935g) is about the size of a large water bottle - perfectly backpackable but not pocket-friendly. The Willen II (100.5mm tall, 360g) is closer to the size of a smartphone, making it genuinely pocket-portable.
Both speakers feature IP67 water and dust resistance, meaning they can handle being submerged in 1 meter of water for 30 minutes. This is particularly impressive for the Willen II given its compact size.
While both speakers offer excellent battery life, there are important differences in their charging capabilities:
The quick-charging feature of the Willen II is particularly valuable for those moments when you realize your speaker is dead just before heading out.
Having tested both speakers in various settings, here's how they perform in different scenarios:
The MEGABOOM 4 clearly wins here. Its 360-degree sound and higher volume output make it ideal for group settings. The sound carries well in open spaces, and the bass remains impressive even outdoors.
The Willen II excels in personal scenarios. Its compact size and mounting strap make it perfect for activities like cycling, hiking, or travel. The sound quality is more than adequate for personal listening, and the clarity of vocals makes it excellent for podcast listening.
Both speakers can serve as decent bathroom or kitchen speakers, but they serve different purposes. The MEGABOOM 4 works better as a primary room speaker, while the Willen II is perfect as a moveable companion speaker.
The MEGABOOM 4 at $149.99 represents solid value for those needing a powerful, versatile speaker. Its superior sound output and features justify the higher price point. The Willen II at $119.99 offers excellent value for those prioritizing portability and personal use, with its quick-charging feature and mounting options adding significant practical value.

The choice between these two excellent speakers ultimately comes down to your primary use case. For group entertainment and more powerful sound, the MEGABOOM 4 is the clear winner. For personal use and ultimate portability, the Willen II offers an impressive package that's hard to beat.
