Choosing Between the Sony ULT FIELD 1 and JBL Go 4: A Complete Comparison

If you're in the market for a portable Bluetooth speaker in 2024, you've probably noticed there are countless options available. Today, we're comparing two notably different approaches: the recently released Sony ULT FIELD 1 ($89.99) and the ultra-compact JBL Go 4 ($44.00). While both are technically portable speakers, they serve quite different needs.

Understanding Portable Speakers in 2024

Portable Bluetooth speakers have evolved significantly over the past few years. The latest models offer impressive sound quality, durability, and smart features that were unthinkable just a few years ago. The key improvements have been in battery life, water resistance, and sound processing capabilities.

The most important factors to consider are:

• Sound quality and volume
• Portability and durability
• Battery life
• Extra features
• Price-to-performance ratio

Design and Portability

The Sony ULT FIELD 1 and JBL Go 4 represent two distinct approaches to portability. The ULT FIELD 1, released in June 2024, is what I'd call "backpack portable" - at 650g and about the size of a large water bottle, it's designed to be carried in a bag. The multi-way strap makes it easy to hang or carry, but it won't fit in your pocket.

The Go 4, launched in April 2024, takes a radically different approach. At just 180g and roughly the size of a deck of cards, it's genuinely pocket-sized. This ultra-portable design makes it perfect for everyday carry, though it comes with some inherent sound limitations due to its size.

Volume and Power

The size difference between these speakers directly impacts their volume capabilities. The ULT FIELD 1 can fill a medium-sized room or outdoor space with sound, making it suitable for small gatherings. Its side-mounted passive radiators (which are like unpowered speakers that help enhance bass response) give it significantly more low-end punch than you might expect.

The Go 4, while impressively loud for its tiny size, is better suited for personal listening or small group settings. It won't be able to power your backyard party, but it's perfect for a desk, hotel room, or picnic blanket.

Sound Character

The ULT FIELD 1's larger size allows for more sophisticated sound processing. Its Sound Diffusion Processor (which helps spread sound more evenly across a space) and ULT bass boost feature provide a fuller, richer sound signature. The speaker delivers clear mids, detailed highs, and surprisingly capable bass, especially with the ULT feature engaged.

The Go 4 focuses on clarity in the mid-range, where most vocals and lead instruments sit. While it can't match the bass response or overall fullness of its larger competitor, it does an admirable job of presenting a balanced sound that works well for podcasts, acoustic music, and general listening.

Battery Life and Charging

Battery technology has improved significantly in recent years, and both speakers benefit from this. The ULT FIELD 1 boasts up to 12 hours of playback, though this varies significantly with volume level and whether the ULT bass boost is engaged. In real-world use at moderate volumes, you can expect about 8-10 hours.

The Go 4 offers 7 hours of rated battery life, with real-world performance typically landing around 5-6 hours at moderate volumes. Both speakers use USB-C charging, with the Go 4 charging slightly faster due to its smaller battery capacity.

Durability and Weather Resistance

Both speakers feature IP67 water and dust resistance, meaning they can be submerged in up to 1 meter of water for 30 minutes. This is a significant improvement over earlier generations of portable speakers, which often only offered splash resistance.

The ULT FIELD 1 adds MIL-STD 810H shock resistance certification, making it more rugged and better suited for outdoor adventures. The Go 4's compact size and rubber edges make it naturally drop-resistant, though it lacks formal shock resistance certification.

Smart Features and Connectivity

Both speakers use Bluetooth 5.3, the latest widely available version, which offers improved range and stability over previous generations. The ULT FIELD 1 adds several premium features:

• Stereo pairing with another ULT FIELD 1
• Companion app with equalizer settings
• Echo cancellation for clearer calls
• ULT bass boost button

The Go 4 keeps things simpler but includes essential controls and can connect to the JBL Portable app for basic settings and updates.

Value Proposition

The Sony ULT FIELD 1 at $89.99 represents solid value for those needing a more powerful, feature-rich speaker. Its sound quality, durability, and additional features justify the premium over budget options.

The JBL Go 4 at $44.00 offers impressive bang for the buck if your primary concern is portability and you don't need room-filling volume. It's an excellent choice for travel or as a secondary speaker.

How to Decide

Choose the ULT FIELD 1 if:

• You need enough volume for small gatherings
• Sound quality is a top priority
• You'll use it primarily outdoors or in larger spaces
• You value extra features like stereo pairing
• Battery life is crucial

Go with the JBL Go 4 if:

• Ultimate portability is your priority
• You're primarily using it for personal listening
• Budget is a major consideration
• You want something simple and straightforward
• You need something that fits in a pocket

In my experience testing both speakers, they each excel in their intended use cases. The ULT FIELD 1 has become my go-to for outdoor activities and small gatherings, while the Go 4 is perfect for travel and desk use. The choice ultimately comes down to your specific needs and how you plan to use the speaker most often.
