When it comes to portable Bluetooth speakers in 2024, we're seeing an interesting divide between truly portable personal audio and what I'd call "portable party speakers." Today, we're comparing two very different approaches with the brand new Sony ULT FIELD 7 ($499) and the established Marshall Emberton II ($120).
The portable speaker market has evolved dramatically in recent years. While basic Bluetooth connectivity was once enough, today's buyers expect features like water resistance, long battery life, and increasingly sophisticated sound quality. What's interesting is how manufacturers are approaching these demands differently.
Released in April 2024, the ULT FIELD 7 represents Sony's latest thinking on party-focused portable audio, with a feature set aimed at creating entertainment experiences. Meanwhile, the Emberton II, released in May 2022, takes Marshall's classic approach of focusing on sound quality and simplicity in a truly portable package.
The ULT FIELD 7's audio system is built around serious hardware: dual tweeters for crisp highs, powerful woofers for midrange clarity, and passive radiators that help deliver impressive bass response. Sony's "ULT POWER SOUND" technology offers two bass modes - Deep Bass for resonating low frequencies and Attack Bass for punchier response. In practice, this means you can tune the speaker for different scenarios, from background music to full-on dance parties.
What's particularly clever is the Sound Field Optimization feature, which uses built-in microphones to analyze the environment and adjust audio settings accordingly. This helps maintain clarity even in challenging acoustic spaces like large rooms or outdoor areas.
The Emberton II takes a different approach, using Marshall's True Stereophonic system - essentially creating an omnidirectional sound field from a compact enclosure. Two 2-inch full-range drivers and passive radiators deliver surprisingly full sound for the size. While it can't match the raw power of the ULT FIELD 7, the sound signature is notably balanced and clear, especially at personal listening volumes.
Having tested similar speakers in various settings, the use case really determines which approach makes more sense. The ULT FIELD 7's power and feature set shine in situations like:
The Emberton II excels in more personal scenarios:
This is where the difference becomes stark. The ULT FIELD 7 weighs in at 14 pounds - it's portable in the sense that you can move it around, but it's not something you'll casually toss in a bag. The integrated handles make transportation manageable, but this is definitely a "setup and leave" kind of speaker.
The Emberton II, at just 1.5 pounds, truly delivers on the portable promise. It's small enough to slip into a jacket pocket or bag side pocket, making it genuinely convenient for spontaneous use.
Both speakers advertise 30-hour battery life, but this needs context. The ULT FIELD 7's 30-hour rating is impressive given its power requirements, but you'll likely see less in real-world use, especially at higher volumes or with features like the LED light show engaged.
The Emberton II's more modest power needs mean its 30-hour rating is more consistently achievable. Its quick-charge feature, providing 4 hours of playback from a 20-minute charge, is particularly useful for the spontaneous use cases it's designed for.
The ULT FIELD 7 comes loaded with features aimed at entertainment:
The Emberton II focuses on core functionality:
Both speakers feature IP67 water and dust resistance, meaning they can handle rain, splashes, and even brief submersion. The ULT FIELD 7's rugged build includes rubberized end caps and feet for stability, while the Emberton II's compact silicone-wrapped chassis feels solid despite its size.
At $499, the ULT FIELD 7 represents a significant investment, but its feature set and power make sense for users who regularly host gatherings or need serious portable sound. The $120 Emberton II offers excellent value for personal use, delivering quality sound and durability in a truly portable package.
In the end, these speakers serve different needs despite both being "portable." The ULT FIELD 7 excels as a party-focused entertainment system that happens to be movable, while the Emberton II delivers on the promise of quality sound you can truly take anywhere.
For home theater use, neither speaker is ideal as a primary solution, though the ULT FIELD 7 could serve as a decent temporary setup for movie nights on a patio or in a garage theater setting. Its stereo separation and power would provide a reasonable experience, but dedicated home theater speakers would be a better choice for permanent installation.
