Choosing Between the Latest Portable Speakers: Sony ULT FIELD 7 vs Marshall Willen II

The Evolving World of Portable Speakers

Portable Bluetooth speakers have come a long way from the tiny, tinny-sounding units of the past. Today's market spans from ultra-portable personal companions to powerful party systems that can rival small PA setups. In early 2024, both Sony and Marshall released new models that showcase just how diverse this category has become.

The $499 Sony ULT FIELD 7 and $119 Marshall Willen II represent opposite ends of the portable speaker spectrum, yet both deliver premium experiences for their intended uses. Let's dive into what makes each special and who they're really meant for.

Size and Portability: A Tale of Two Approaches

The first thing you'll notice is the dramatic size difference. The ULT FIELD 7 is a substantial piece of equipment at 20 inches wide and weighing 14 pounds - think small suitcase. While it has convenient carrying handles and a rugged build, "portable" here means "moveable between locations" rather than "slip it in your bag."

In contrast, the Willen II is remarkably compact at just 4 inches square and under 2 inches deep. At less than a pound, it's genuinely portable - the kind of device you can clip to a backpack or bike with its built-in rubber strap and barely notice it's there.

Sound Performance: Understanding the Trade-offs

Volume and Power Handling

The ULT FIELD 7 packs serious power with its multi-driver setup. It uses what Sony calls "X-Balanced Speaker Units" - essentially non-circular speaker drivers that maximize the cone area within the cabinet space. This means more air movement and higher potential volume without distortion. The speaker can easily fill a large room or outdoor space with clean, powerful sound.

The Willen II takes a different approach, using a single high-quality 2-inch driver paired with passive radiators (non-powered speakers that move in response to air pressure inside the cabinet). While it can't match the raw volume of its larger rival, it's surprisingly loud for its size and maintains clarity at its maximum output.

Bass Response and Sound Quality

Here's where the size difference really shows its impact. The ULT FIELD 7's large woofers and cabinet volume allow it to produce genuine deep bass - the kind you can feel. It has two different bass modes: "Deep Bass" for that room-filling boom, and "Attack Bass" for tighter, more punchy low end that works better for genres like rock and jazz.

The Willen II, despite clever engineering with its passive radiators, simply can't move enough air for deep bass. However, Marshall has tuned it to provide a satisfying sense of low end without trying to overreach. The focus instead is on clarity and balance across the frequency range it can reproduce well.

Technical Innovations and Features

The ULT FIELD 7 introduces several new technologies:

• Sound Field Optimization uses built-in microphones to analyze the environment and adjust audio settings for optimal sound
• Party Connect allows linking multiple compatible Sony speakers for synchronized audio and lighting
• LED lighting systems that sync with the music
• Karaoke and guitar inputs for expanded entertainment options

The Willen II brings its own innovations:

• Stack Mode for wireless pairing of multiple units
• Future Auracast support for advanced Bluetooth broadcasting
• Upgraded Bluetooth 5.3 with exceptional range (up to 100m in open field)
• Refined single-driver design that maximizes performance from minimal space

Battery Life and Practical Use

Battery performance scales with size here. The ULT FIELD 7 offers 30 hours of playback, which is impressive given its power output. The Willen II provides 17 hours, which is actually more efficient when you consider its size and weight.

Both feature quick charging capabilities - particularly useful for the Willen II, where a 20-minute charge provides 5.5 hours of playback.

Value Proposition and Real-World Use

While the price difference is substantial, it's important to understand these serve different purposes:

The ULT FIELD 7 at $499 competes with other party speakers and even small PA systems. For someone who regularly hosts gatherings or needs powerful portable sound, it's a worthwhile investment. The sound quality, durability, and feature set justify the price for its intended use case.

The Willen II at $119 represents the premium end of personal portable speakers. The build quality, sound performance, and thoughtful design features make it a strong value for those wanting high-quality personal audio on the go.

How to Make Your Choice

Consider these key questions:

1. What's your primary use case? Personal listening vs. group entertainment?
2. How important is true portability?
3. Do you need deep bass reproduction?
4. What's your realistic budget?

Choose the ULT FIELD 7 if:

• You frequently host parties or outdoor gatherings
• Deep bass response is crucial
• You want a single speaker solution for larger spaces
• Additional features like karaoke or guitar inputs appeal to you

Choose the Willen II if:

• True portability is essential
• You primarily listen alone or in small groups
• You want premium sound in a compact format
• You're looking for the best personal speaker under $150

Final Thoughts

Both speakers excel at their intended purposes. The ULT FIELD 7 provides powerful, room-filling sound with deep bass and party features, while the Willen II delivers impressive personal audio in an ultra-portable package. The choice ultimately comes down to your specific needs and use cases rather than one being "better" than the other.
