Sony ULT Field 1 Review: The New Bass-Heavy Bluetooth Speaker Contender

In the ever-evolving landscape of portable audio, the demand for a Bluetooth speaker that delivers robust sound while enduring the rigors of an active lifestyle has never been higher. Sony, a household name synonymous with audio innovation, steps into this competitive arena with its ULT Field 1. Pitched as a formidable challenger, especially for those who crave deep bass, this speaker aims to capture the hearts and ears of outdoor enthusiasts and party-goers alike. This review delves into whether the ULT Field 1 truly lives up to its “bass-heavy contender” moniker, examining its design, sound capabilities, features, and how it stacks up against established rivals.

The Rise of Portable Bluetooth Speakers

The market for portable Bluetooth speakers has exploded, driven by consumers seeking versatile audio solutions for everything from backyard barbecues to wilderness adventures. Modern portable speakers aren’t just about playing music; they are expected to withstand the elements, offer impressive battery life, and most importantly, deliver captivating sound. The Sony ULT Field 1 enters this space, targeting users who prioritize durability and a powerful low-end, aiming to carve out its niche among the best portable Bluetooth speakers available today.

Sony ULT Field 1: Design & Durability

The Sony ULT Field 1 adopts a pragmatic and robust design, presenting an oblong form factor with thoughtfully curved edges and rubberized grips at both ends. This design prevents it from rolling off surfaces and provides a tactile, secure feel. The central section of the speaker is encased in a tightly woven fabric, available in a palette of black, grey, green, and orange, offering both subtle and vibrant aesthetic choices.

Durability is a cornerstone of the ULT Field 1’s appeal. It boasts an IP67 rating, making it highly resistant to both dust and water, capable of being submerged in up to a meter of water without adverse effects. This means you can confidently take it to the beach, by the pool, or out in the rain without a second thought. Furthermore, Sony emphasizes its shockproof construction, claiming it can withstand drops and impacts from over a meter, reinforcing its readiness for rugged adventures. A convenient, color-matched elastic string carrying strap is also included, enhancing its portability and ease of transport.

Unleashing the Bass: Sound Quality & The ULT Mode

At the core of the Sony ULT Field 1’s identity is its commitment to powerful audio, particularly its celebrated bass response, primarily driven by the ULT Power Sound mode. Without ULT activated, the speaker offers a generally “solid sound” with good power and acceptable detail, characterized by a lighter and sharper tonality. It presents music with more air and clarity in the mids and highs.

However, the magic truly happens when you engage the ULT button. This feature provides a “palpable boost to bass,” adding significant “lower-end muscle” that can transform the listening experience. For a portable Bluetooth speaker of its size, this enhanced bass is particularly beneficial in outdoor settings where low frequencies often dissipate. While the bass can sometimes feel “heavy-handed, boomy, and lacking in tautness,” it undeniably offers a robust heft beyond what you might expect from similarly sized units. This makes it well-suited for genres that thrive on a strong rhythm section and for filling larger outdoor spaces with sound.

Despite its bass prowess, some compromises exist. The speaker tends to downmix stereo content to mono, which can detract from the spatiality of some tracks. Additionally, while capable across various genres, it truly shines with harder, louder material. What Hi-Fi? noted that the ULT Field 1 surprisingly unearths “more nuance and textural subtleties” than some competitors, especially at higher volumes, proving it can go louder than expected.

Key Features and Connectivity

The Sony ULT Field 1 is equipped with modern connectivity and user-friendly features. It utilizes Bluetooth 5.3 for stable and efficient wireless pairing with your devices. Charging is facilitated via a USB-C port, discreetly located behind a protective flap to maintain its IP67 rating.

For personalized audio experiences, Sony provides its Music Centre app, which allows users to tweak EQ settings. While the app is functional, some reviewers found the onboard 3-band equalizer to be a bit “fiddly” compared to more streamlined competitor apps. Additional functionalities include a speakerphone for hands-free calling, Stereo Pair to link two ULT Field 1 units for wider sound, and Fast Pair for quick, seamless connection with Android devices.

Battery Life: Power for Your Adventures

Battery performance is a critical factor for any portable Bluetooth speaker. The Sony ULT Field 1 is advertised to deliver up to 12 hours of playtime, a figure that held up in testing under moderate volume levels with the ULT mode engaged. This duration is generally considered acceptable for speakers in its class, ensuring it can last through a full day’s outing or a lengthy party.

However, a significant consideration for bass enthusiasts or those who love loud music is the dramatic drop in battery life at maximum volume. According to Sony’s official documentation, the ULT Field 1 can last only about 3 hours when played at its loudest setting. This trade-off between volume/bass and endurance is crucial for potential buyers, especially if the speaker’s primary use involves high-volume listening in environments like parties or outdoor gatherings.

Sony ULT Field 1 vs. The Competition

The Sony ULT Field 1 enters a highly competitive market dominated by established players like JBL and Ultimate Ears. Its most direct rival is often considered the JBL Flip 6, a speaker of similar size and shape. While the ULT Field 1 offers a compelling rugged build and powerful bass, particularly with its ULT mode, the Flip 6 often receives praise for its “cohesion” and “three-dimensionality” in sound, managing textures and elements more adeptly. Some suggest the JBL has more “heft in the upper-midrange,” an area where the Sony can occasionally sound “hollowed out or a tad incomplete.”

Against alternatives like the Ultimate Ears Wonderboom 4, the ULT Field 1 provides a more traditional cylindrical design compared to the Wonderboom’s globe-like form. The Wonderboom is often lauded for its robust 360-degree sound, though the ULT Field 1 pushes harder on sheer bass impact. Ultimately, the choice often comes down to specific sound preferences: the ULT Field 1 for those prioritizing powerful, boosted bass, and competitors like the Flip 6 for a more balanced and cohesive sound profile.

“The ULT Field 1 presents a fairly compelling case for competition in the portable speaker market – it immediately marks itself out as a proper contender if you’re on the hunt for a new rugged speaker. It’s small enough to be genuinely portable, has proper durability, and sounds very solid indeed.” – Max Freeman-Mills, Staff Writer, T3.com

Buying Guide Considerations

When considering the Sony ULT Field 1, align it with your specific needs:

  • Primary Use: If you need a durable, portable companion for outdoor activities, beach trips, or casual home listening where powerful bass is a priority, the ULT Field 1 is a strong candidate.
  • Budget: Priced around $130 (often found for less), it falls into a competitive mid-range segment. Compare current deals with rivals like the JBL Flip 6 or UE Wonderboom 3/4.
  • Desired Features: Value IP67 waterproofing, shockproofing, and a dedicated bass boost button? The ULT Field 1 excels here. If extended battery life at max volume or precise stereo imaging are paramount, you might consider alternatives.

Optimizing Your ULT Field 1 Experience

To get the most out of your Sony ULT Field 1 Bluetooth speaker, consider these tips:

  • Connecting with Ease: Utilize Bluetooth 5.3 for a stable connection. For Android users, Fast Pair offers a near-instant setup. If you own two ULT Field 1 units, enable Stereo Pair for a broader, more immersive soundstage.
  • Maximizing Sound Quality: Experiment with the ULT Power Sound mode. While it provides a significant bass boost, try listening with it off in quieter indoor environments to appreciate the speaker’s “lighter, freer” sound profile. Use the Sony Music Centre app to fine-tune the 3-band EQ, though be mindful of its slightly “fiddly” nature.
  • Care and Maintenance: The IP67 rating ensures resilience against water and dust. After exposure to water, ensure the USB-C charging port flap is securely closed and allow the speaker to dry fully before charging. Clean the exterior with a soft, damp cloth. Always store it in a cool, dry place when not in use to prolong its lifespan.

Conclusion

The Sony ULT Field 1 positions itself as a robust and portable Bluetooth speaker that delivers on its promise of powerful bass, especially with the ULT Power Sound mode activated. Its exceptional durability, evidenced by its IP67 rating and shockproof design, makes it an ideal companion for any adventure. While it shines with its impressive low-end and detail retrieval, it faces stiff competition, particularly from the JBL Flip 6, which often offers a more cohesive and balanced sound profile across the frequency range.
