check best priceSummary / TL;DR
The Sony ULT Field 3 mobile speaker presents a mix of powerful sound and sleek design, aiming to stand out in a crowded market. It boasts a robust build, compact size, and features like ULT bass boost and 7-band EQ customization. Priced at $200, it may not suit all budgets, but it offers durability and IP67 waterproofing for those prioritizing these aspects.
Design-wise, the speaker is both stylish and functional, though slightly bulkier than some ultra-portable models. It offers impressive audio clarity with robust bass, though the treble may lack some sparkle. While it provides up to 24 hours of battery life, this dwindles at high volumes, and charging could be faster.
The speaker supports Bluetooth 5.3 and has a 3.5mm AUX input but lacks Wi-Fi and NFC, which might be a downside for some users. The intuitive controls are easy to use, though button spacing could be improved. Compared to competitors, it holds its ground with a blend of sound quality and durability, though faster charging and more responsive controls would enhance its appeal.

The market for mobile speakers is packed with options, but the Sony ULT Field 3 aims to stand out with its blend of powerful sound and sleek design. Whether you're planning a beach day or a backyard BBQ, this speaker is designed to bring the party wherever you go. But does it live up to the expectations? In this review, we'll take a closer look at what makes this speaker tick.
Mobile speakers are all about convenience and portability, and the Sony ULT Field 3 promises to deliver on both fronts. With its robust build, compact size, and detachable shoulder strap, it's crafted to be your go-to audio companion. However, it's not just about being portable. The speaker also pledges to offer an immersive audio experience with features like ULT bass boost and 7-band EQ customization, which is a bold claim in today's competitive market.
Before diving into the nitty-gritty details, it's essential to mention that while this speaker packs a punch in many areas, it might not be the perfect fit for everyone. Some users might find its $200 price point a bit steep compared to other options available. Nevertheless, for those who prioritize sound quality, durability, and IP67 waterproofing, this speaker could be worth the investment.
Design and Build Quality
The design and build quality of a mobile speaker can make or break your experience, and the Sony ULT Field 3 certainly makes a statement. At first glance, you'll notice its sleek and modern design, which is not only eye-catching but also functional. The speaker's body is crafted from durable materials that provide both a premium feel and a sturdy build. This ensures that it can withstand daily wear and tear, making it a reliable companion for your adventures.
The Sony ULT Field 3 is relatively compact, making it easy to carry around in your backpack or even a large pocket. If you're someone who loves taking your tunes on the go, you'll appreciate its portability. However, while it's lightweight, some users might find it a bit bulkier compared to other ultra-portable models on the market.
On the exterior, the speaker features a waterproof and dustproof design with an IP67 rating, which is perfect for outdoor use. Whether you're at a beach party or just chilling by the pool, you won't have to worry about splashes or dust ruining your fun. It can be submerged in water up to 1 meter for 30 minutes without damage.
The controls are well-integrated into the design, with tactile buttons that are easy to press, even in low-light conditions. The buttons are intuitively placed, so you won't find yourself fumbling around to adjust the volume or change tracks. Overall, the Sony ULT Field 3 impresses with its robust build and stylish design. It's a speaker that's built to last, but a slightly slimmer profile would make it even more appealing for those who prioritize ultimate portability.

Sound Performance
The sound performance of the Sony ULT Field 3 is a real treat for your ears This mobile speaker packs a punch with its impressive audio clarity and depth. Equipped with a woofer, two passive bass radiators, and a tweeter, it delivers robust bass that doesn't overpower the mids and highs. If you're a fan of bass-heavy music, you'll appreciate the rich low-end frequencies it produces without losing clarity in other ranges. The speaker does not have a 360-degree sound capability, but it offers a wide soundstage that is suitable for various environments. The sound remains crisp and detailed even at higher volumes, though at maximum volume, there might be a slight distortion. However, it's not a dealbreaker unless you're trying to throw a massive party.
On the downside, the speaker may not fully satisfy audiophiles looking for the most pristine audio quality. The treble can sometimes feel a bit restrained, lacking that extra sparkle. But for casual listeners and everyday use, the balance between different sound elements is generally well maintained. Overall, the ULT Field 3 offers a sound experience that is both enjoyable and immersive, making it a great companion for your music adventures. If you're looking for a speaker that delivers solid performance without breaking the bank, this one is worth considering. Just be mindful if you're an audiophile on the hunt for the ultimate sound precision.

Battery Life and Charging
When it comes to battery life, the Sony ULT Field 3 offers up to 24 hours of continuous playtime on a single charge. That's plenty for a day at the park or an outdoor party! But let's be honest, if you crank up the volume to its max, expect that number to dwindle to around 5 hours.
The charging process is pretty straightforward. The speaker uses a USB-C port, which is a nice touch since it's becoming the standard for most devices. You won't have to rummage through a pile of old cables to find one that fits. Charging from zero to full takes around three hours, which is decent but not exactly lightning fast. If you're someone who forgets to charge your gadgets, you might want to keep that in mind.
One feature that's worth mentioning is the power-saving mode. If you forget to turn it off, the speaker will automatically shut down after a period of inactivity, conserving battery life. It's a small but useful touch for those of us who are a bit forgetful.
While the battery life is generally satisfactory, if you're planning a multi-day camping trip without access to power, you might want to consider bringing along a portable charger as a backup. Overall, the Sony ULT Field 3 does a commendable job in the battery department, but there's always room for improvement, especially with faster charging options.
Connectivity Options
If you're all about staying connected, the Sony ULT Field 3 has got some cool options for you. First off, this speaker supports Bluetooth 5.3, which means faster pairing and a more stable connection compared to older versions. You can wander around your room without worrying about losing signal—up to around 30 feet, give or take. For those who like to keep it old school, there's a trusty 3.5mm AUX input. This is perfect if you're looking to connect devices that might not have Bluetooth. It's a nice touch for people who value versatility in their gadgets. Now, if you're into group listening sessions, the Party Connect feature lets you link up multiple compatible Sony speakers. It's a neat way to spread the sound and amplify your music experience.
Just imagine having a few of these bad boys synced up at your next get-together! However, there's a small hiccup. The speaker doesn't support Wi-Fi connectivity, which could be a bummer for those who enjoy streaming music directly from the internet without relying on their phone's data. Also, there's no NFC for quick pairing, which some folks might miss. On the charging front, the speaker uses a USB-C port, which is a big win. It's becoming the standard for devices, meaning you can use the same cable for multiple gadgets. Plus, it charges pretty quickly, so you won't be left hanging when you need to juice up.
Overall, the connectivity options on the Sony ULT Field 3 are pretty solid, especially with the Bluetooth 5.3 and USB-C. Just keep in mind the lack of Wi-Fi and NFC, which might be dealbreakers for some. But hey, if those aren't on your must-have list, this speaker's got you covered for most situations.

What's in the Box
So, you've got your hands on the Sony ULT Field 3, and you're probably curious about what goodies come packed in the box. Let's break it down for you.
First up, you'll of course find the mobile speaker itself. It's securely cushioned to prevent any damage during transit. Sony doesn’t skimp on the packaging, which is always a plus when you’re investing in tech that you want to last.
Alongside the speaker, you'll receive a USB-C charging cable. It's not the longest cable out there, but it does the job, and it's compatible with many other devices, which is super handy. Unfortunately, there’s no wall adapter included, so you’ll need to use one you already own or charge via a USB port on your computer.
There's also a quick start guide to help you get up and running in no time. It’s pretty straightforward, with diagrams that make the setup process a breeze, even for those who aren’t tech-savvy.
Finally, you’ll find some warranty information tucked away in there. It's always a good idea to glance over this to know what’s covered, just in case you encounter any issues down the line.
While the box includes the essentials, some users might miss having a carrying pouch or case to protect the speaker on the go. However, the speaker itself comes with a detachable shoulder strap, which aids in portability. But overall, the contents are practical and ensure you’re set for an enjoyable audio experience right out of the box.
User Interface and Controls
So, let's chat about the user interface and controls on this nifty gadget. At first glance, the controls on the Sony ULT Field 3 are pretty straightforward, which is a big win in my book. You've got your usual suspects: power, volume, and play/pause buttons right on top, making them easy to access whether you're lounging on the couch or having a backyard BBQ.
The buttons have a nice tactile feel—they're not too stiff, so you won't have to wrestle with them to get your tunes going. However, they could have been a tad more spaced out. If you've got bigger fingers, you might find yourself accidentally hitting the wrong button now and then.
There's also a handy Connect button, which makes linking to other speakers or pairing easier. No need to scroll through endless menus on your device—just press the button, and you're ready to rock. And speaking of Bluetooth, the speaker gives a nice auditory cue when it's connected, so you're not left guessing if it worked or not.
On the downside, while the speaker supports customization through the Sound Connect app, there is no dedicated app solely for the ULT Field 3. Some folks might miss having the ability to tweak EQ settings or update firmware directly from their phone. But if you're someone who prefers a more 'set it and forget it' approach, this won't be a deal-breaker.
Overall, the controls are intuitive, and while they might not offer every bell and whistle, they do the job without any fuss. Just be mindful of the button spacing, and you'll be good to go!

Competitor Comparison
Bose SoundLink Flex
The Bose SoundLink Flex is a popular choice for those who prioritize compactness and a sleek design. Bose tends to focus on delivering balanced sound with a slight emphasis on bass. However, if you’re a fan of fuller and more immersive sound, the Sony ULT Field 3 might have the edge with its broader soundstage and dynamic range.
JBL Charge 5
JBL is known for its rugged and durable speakers, and the Charge 5 is no exception. It comes with an IP67 rating, making it highly resistant to dust and water. The Sony ULT Field 3 also offers robust durability with a similar IP rating, but it might win you over with its more refined aesthetic appeal and slightly better sound clarity at higher volumes.
Ultimate Ears Boom 3
The UE Boom 3 is renowned for its 360-degree sound and vibrant design options. It’s great for parties with its loud and punchy audio. The Sony ULT Field 3, on the other hand, may appeal to those who prefer a more subdued design and a sound profile that emphasizes detail and precision over sheer loudness.
Anker Soundcore Motion+
For budget-conscious buyers, the Anker Soundcore Motion+ offers impressive sound quality at a lower price point. It features aptX support and a customizable EQ. While the Sony ULT Field 3 might come at a higher price, it often compensates with superior build quality and a more user-friendly interface.
In conclusion, the Sony ULT Field 3 holds its ground well against competitors by offering a blend of sound quality, durability, and a design that appeals to those who appreciate a touch of sophistication. That said, if budget constraints or specific features like 360-degree sound are your priority, exploring other options might be worthwhile.
Conclusion
In summary, the Sony ULT Field 3 offers a compelling package for those in search of a reliable mobile speaker. Its sleek design and robust build quality make it a durable choice for both indoor and outdoor use. The sound performance is impressive, delivering clear highs and deep bass, ensuring your music sounds great no matter the genre.
Battery life is another strong suit, providing up to 24 hours of playback, which is perfect for long trips or parties. The charging process is straightforward, though it could be faster for those who are always on the go. Connectivity options are versatile, with Bluetooth and auxiliary inputs that make pairing with various devices a breeze. However, the lack of NFC might be a downside for users who value quick and easy connections.
The user interface is intuitive, with controls that are easy to navigate, though the buttons could be more responsive. In the competitive landscape of mobile speakers, the Sony ULT Field 3 holds its own, offering a good balance of features and performance.
While it excels in many areas, it could benefit from a more rapid charging capability and slightly more responsive controls. Overall, it’s a solid choice that will satisfy most users looking for a dependable and high-performing mobile speaker.

Whether you're using it for a party or a quiet evening at home, the sound performance is consistently solid. The design and build quality are also noteworthy. It's built to last with durable materials, and its sleek, modern design makes it a stylish addition to any space. Although it is designed to be carried in one hand, it might be a tad bulky for those looking for an extremely compact option.
In terms of battery life, it offers up to 24 hours of playtime on a single charge, though this reduces to about 5 hours at maximum volume. The charging process is straightforward, although it could be faster. If you're planning on using it for extended periods without access to a power source, you might find yourself wishing for a quicker recharge.
