Customer Ratings & Reviews

It is one of the best compact speakers with solid sound quality. It has an IP67 rating, which means it is water-resistant. It is not IP68 like JBL speakers of a similar size and price, which are fully waterproof. Other than that, the sound quality is phenomenal, and the battery life is also very good. One feature I really like is the protective cover on the charging port. This makes it great for outdoor use, such as at the beach, because it helps protect the port from water and dust. Compared to alternatives like JBL, Bose, or Beats, this feature is not always available. In my opinion, the sound quality is overall better than its competitors, and I recommend this product.

What I like best is the sound that this speaker produces. Clear, loud, crisp, and the bass sound is unmatched. My daughter asked for a speaker to play her graduation song and this delivered. Thumbs up for that. The extra bonus is the carrying strap. What a smart idea! It came in extra handy when your hands are full. Thanks Sony!!

I recently got the Sony ULT Field 1 and loved it so much that I ended up picking up the bigger ULT Field 3 as well. At higher volumes, the ULT Field 3 definitely delivers a much deeper bass compared to the Field 1, and the vocals come through clearer too. I think ult field 3 is a sweet spot in size not too small not too large to put it in a back pack. Overall, I’m really impressed with this speaker. Even though I also have the JBL Authentics 500, I find myself constantly reaching for the ULT Field 3—it just makes music so enjoyable to listen to. I really appreciate the ULT button. Some people say it’s pointless because they never feel the need to turn it off, but personally, when I’m watching videos, I like to switch it off to reduce the bass and keep the focus more on vocals. If there’s one thing I wish it had, it would be a USB audio connection. I know JBL’s Charge 6 includes this feature, so I was hoping Sony would too. But other than that, in terms of sound quality and design, I think the Sony ULT Field 3 is easily the best portable speaker for summer 2025.

Pleasantly surprised at the sound quality of such a compact subwoofer/speaker. Very stylish easy to operate and was a good investment.

It's a great speaker, much better than others in the same segment. I was comparing this one to JBL, and Sony definitely wins; for the price and quality, it's worth it. The only thing I wish was possible is to adjust the equalizer within the Sony app. I also wish you could connect it to other speakers for a home theater setup or with Alexa. That’s the only part that disappointed me a bit—I expected it to be smarter. Other than that, the sound is great and the battery life is excellent.

With the bass boost on I get 9 hours of play time. If I use it without the bass boost I get almost triple that time. Great quality sound even with the boost off. DEFINATELY well worth the money.

Great,long time working,bass ,volume power, It looks beautiful

Talk about a speaker that blows you away. When looking for a speaker in store, this one literally blew us away by being the perfect size and louder than the others. It is a no brainer to me.

Great sound for the price. I also like the auto shut off to spare the battery when you haven't played anything on it for awhile.

Someone stole the last Bose I owned that I purchased last from Best Buy. So this was a great replacement until I finish paying off the Bose on my account. I had to settle with a smaller more compact one but it was worth it. I will eventually get another Bose once again in the future.

Bought this as a speaker I can listen to while wrenching on my cars in my garage. The audio quality is impressive, but the bass is not as solid as other reviewers have made it out to be. Still though, I would definitely buy this again as it sounds good and looks good.

The Best wireless speaker ever. 100% recommend. The sound it’s absolutely amazing

the sound profile considering the size of this speaker is awesome. this usually sits outside on my patio so we don't use it full blast even at lower volumes its still very clear.

Amazing quality for a sound system , it really does look great and it get the job done honestly Thank you and great work

Simply AWESOME! I optimized it in my home as well as my vehicle. The quality and sound is Great!!!

I have a love hate relationship with this thing! The sound is great! It just happens to cut out unexpectedly sometimes. Not sure if it’s my device causing that or what. Aside from that the speaker has a great sound. Even while outside, it could get your perimeter moving.

Sony ULT Field 3: Built for Bass I grew up in the 80's and 90's when everyone had a jam box. The Sony ULT Field 3 is what I always wish I had when we were swimming, camping, or just hanging out. It's the perfect music box, or rectangle, for outdoors and after putting it through some real-life testing—indoors, outside, and even during a backyard party, I’ve got a pretty clear picture of what this speaker can do. This speaker is part of Sony’s newer “ULT” line, which is focused on deep bass, high volume, and performance. If you’re into outdoor activities, like hanging out at the pool, sand volleyball, beach trips, or just having music with you wherever you go, this is a must have. *Design & Build Quality* The build is one of the speaker’s best features. It feels solid and durable right out of the box. It has a tough rectangular design with soft-touch plastic on the sides and a solid fabric mesh across the front and back. The speaker feels like it’s made to be thrown in a backpack or taken on a trip and it can handle some bumps. It's lightweight for carrying too. It’s IP67-rated, so it’s waterproof, dustproof, and resistant to drops. The first place I took this speaker was a backyard get together with kids and water splashing everywhere. I even rinsed it under the faucet to clean off some dirt, and it didn't miss a beat. Definitely a good choice if you’re out in the elements. There are rubber feet on one side for horizontal placement, but you can also stand it vertically. That’s useful depending on how much space you’ve got. The controls are on the top: power, bluetooth, volume up/down, play/pause, and a special ULT button that boosts the bass. The buttons are easy to feel, so you don’t have to guess in the dark or when you’re outside. There’s also a detachable strap that lets you sling it over your shoulder. I love the idea, but actually getting the strap unhooked from the built-in clips was kind of a pain. In a way, that's good because you don't have to worry about it becoming detached. Once it's on, though, it makes carrying the speaker much easier and it kind of reminds me of carrying the music around back in the day. *Setup and Features* The ULT Field 3 is easy to setup too. I turned it on, opened my phone’s Bluetooth, and it showed up right away. What’s nice is that it supports 2 devices simultaneously, which means I could stay connected to both my phone and laptop at the same time. No need to keep disconnecting and reconnecting. Charging is done through USB-C, and you can use it as a portable power bank. I actually charged my phone from it during a long day outside, it’s not a fast charge, but it’s enough to get your phone going again. If you download the Sony app called Sound Connect, you get access to some extra features, including: A 7-band equalizer to tweak the sound Switching sound modes (default, ULT mode, and custom EQ) One cool new feature is the DJ control. You've got 8 features that you can add to the music for a little bit of fun or a few laughs. There's Robot, Drums, Scratch, Audience, Voice Phaser, Reggaehorn, and Rhythm. You can also turn on an isolator or dial in the Custom EQ. *Sound Performance* Here’s where things get fun. This speaker is all about the bass. Even without turning on the ULT mode, the low-end is already strong. But when you hit that ULT button, it really shows it's bass gets punchier, deeper, and more noticeable, especially on songs with lots of beats or low tones. Pro-Tip: Turn the bass boost off for longer battery life. I tested a variety of music from 80's to Hip-Hop, Rock, and even movie soundtracks. I really noticed the power when I was in my backyard. We didn't even have the speaker on at its highest volume. Vocals and mid-range sounds come through fairly clearly, though I did notice that if you crank the volume and keep the ULT mode on, the bass can start to overpower. The highs can also sound a little sharp at really high volume—especially if you’re indoors or standing close to the speaker. Outdoors, the sound spreads better and stays more balanced. One thing to note: this isn’t a 360-degree speaker. The sound comes out in one direction, so it’s best to point it toward wherever the people are. It gets loud enough for small parties or group hangs, but placement makes a big difference. *Battery Life* Battery life is one of the speaker’s strong points. Sony claims up to 24 hours, and that's fairly accurate at medium volume without the ULT mode on. With ULT mode and higher volume levels, I was getting closer to 5 or 6 hours, which is still decent considering how powerful the bass is. There’s also a quick charge feature. I tested this a few times: 10 minutes of charging gave me around 2 hours of playtime, which helps if you're hanging all day at the pool, or if you forget to charge it and the battery is low. The app give you the battery percentage, but you can also turn on an option, in the app, that tells you the battery percentage when you turn the device on. *Pros* IP67 is great for all outdoor settings Powerful Bass and great sound really surprises you from such a compact speaker Long battery life with fast charging You can charge your phone Carrying Strap Multipoint connection App gives you a few added extras *Needs Improvement/Ideas* Bass can drown out vocals at high volume Treble sounds a little harsh at high volume Sound only goes in one direction Strap is a little difficult to take off *Final Thoughts* The Sony ULT Field 3 is a great speaker if you’re the type of person who wants music that’s loud, full of bass, and you like the outdoors. It’s not the most balanced speaker if you’re an audiophile, but for casual listening, parties, and outdoor fun, it’s a great addition. It’s well built, it's Sony, and the sound is powerful. If you want something that can survive the outdoors, and liven up the party, it's a must-have. Believe me, this is not your typical bluetooth speaker, I highly recommend it.

The Sony ULT FIELD 3 speaker is a recent addition to the ULT family of portable Bluetooth speakers. Sony has designed the ULT 3 for people on the go, and have made it easy and convenient to take along and share your music with others. The ULT 3 contains one tweeter, one woofer, and two passive radiators (one at each end) that provide a rich, full sound for music, yet you can turn the bass down for podcasts and phone calls so they aren’t “boomy” sounding when listening to speech. While it is not a stereo unit, it can be combined with other Sony ULT speakers to provide a true stereo experience using the Party Connect function. The “ULT” feature is an added bass boost that can be turned on or off using a dedicated button on the control panel that lights up when activated (the color changes depending on viewing angle). However, the ULT 3 does not have the “party lights” feature of the other, larger units in the series. The ULT 3 is designed to be waterproof, dustproof, shockproof, and rustproof to IP67 standards. That makes it suitable for outdoor use, including the beach. The exterior of the speaker is covered with a textured, woven, fabric-like covering that while being able to withstand water and dirt, also feels pleasing to the touch and offers a surface that is readily grippable. The width, or thickness, of the speaker is such that most people should be able to easily pick it up with one hand to carry it. There are two mounts on the top surface of the unit that allow the included shoulder strap to be easily attached and detached. This strap is slightly over one inch wide and allows for the speaker to comfortably hang from your shoulder. The ULT 3 has a bit of heft to it, giving it the feel of a quality item but is not overly weighty where it would be tiring to carry. The controls are on the top surface of the speaker and the markings are raised and colored to make them easy to see and use. The buttons have a nice amount of haptic feedback when pressed. While the ULT 3 is designed to sit with the long edge down, it can also be set on either end without causing issue to the sound quality. The passive radiators on the ends are also vented around their perimeter to allow for air movement when the speaker is set on end. Sony claims up to 24 hours of battery life with the volume set at “22”. According to the online “Help Guide” from Sony’s website, the maximum volume setting is “50”, so a setting of 22 is slightly less than 50 percent of maximum volume. The online Help Guide is 98 pages long and is well worth reading through as there is so much more information contained in it than what is presented in the rather rudimentary “Reference Guide” that is in the box. The pages are not full of text and diagrams, so it isn't as long as 98 pages implies. Besides the speaker unit, the ULT FIELD 3 comes with a paper Reference Guide, a paper Limited Warranty pamphlet, the aforementioned shoulder strap, and a 20 inch long charging cord. The included USB-C to USB-C charging cord is very thick and stiff, and does not offer much length limiting your charging locations to where you can safely place the ULT 3 while plugged in. There is no charging adapter included as is the case with just about every rechargeable device nowadays. It is recommended to use a charging adapter that outputs either 5 volts or 9 volts at 3.0 amps. That is the equivalent of 15 to 27 watts, or similar to the same amount that most modern smartphones want for charging. Sony claims a run time of 120 minutes after 10 minutes of charging, but makes no mention (that I could find) of the required adapter output to achieve this. The charging port is under a gasketed cover on the back side of the speaker along with a button to press to check the amount of battery power remaining. The USB-C port for charging also works in reverse, allowing you to charge your smartphone from the ULT 3’s battery. Be advised the output is only 7.5 watts which is way below what a modern smartphone will accept for charging current, so it will take awhile to charge your phone from the speaker. The Sony ULT FIELD 3 Bluetooth speaker is a stylish and well made product that is at home providing entertainment indoors or in other less than pristine environments and is capable of sloughing off grime and water splashes. Sound quality is subjective, but with the deep bass the ULT 3 is capable of, combined with the crisp highs, just about everyone will be more than pleased with its performance.

The speaker’s design immediately caught my eye. The grayish-white rubber and fabric finish, coupled with the chrome branding, exudes a stylish and elegant aura. Despite its slightly larger size compared to a mid-size portable speaker, it’s surprisingly lightweight, making it easy to hold in one hand. However, it’s not suitable for clipping to a backpack while on the go, but the included shoulder strap compensates for this. The IP67 rating ensures its water resistance, and I tested it with a light shower, which it handled effortlessly. Moreover, the USB-C charging port is cleverly covered by a rubber flap, providing protection against accidental damage. After pairing the speaker and updating the software through the app (which takes a bit of time), I was pleasantly surprised by the refined audio quality. Contrary to my expectations, I didn’t find an overbearing bass, but rather punch and deep impact. The midrange is surprisingly forward and clear, while the treble soars without any harshness. Even when the ULT bass boost is enabled, the sound remains consistent. You can always adjust the sound signature with the app’s EQ. The speaker can produce impressive volume and is easily heard in a large space. I paired it with my projector, and while it’s not a stereo speaker, it managed to create a cinematic experience. The forwardness of the midrange was particularly noteworthy, as dialogue came out exceptionally clear, sometimes even surpassing the quality of an Atmos system. The battery life is impressive. Sony claims 24 hours, and I believe this estimate is accurate. I managed to drain only 40% of the battery in a workday (10 hours), and a mere 10 minutes of charging added approximately 2 hours of playtime. Additionally, it functions as a battery bank, effectively charging my phone and tablet. However, setting up the party function can be a bit confusing. I had to update my SRS-XG300 speaker’s software through Sony’s other app and perform a series of button presses. Nevertheless, once the setup was complete, I was able to place one speaker in the kitchen and another in the living room (approximately 50 feet apart) while my phone was in an office. There are a few minor issues to consider. While the speaker looks visually appealing, I’m concerned that the white finish may get dirty and the fabric fray easily, especially during outdoor activities like camping. Additionally, it lacks USB-C audio connectivity, which is a downside for some users. Lastly, I own a ULT 1 speaker, and it’s not compatible with the Party Function, which is a shame. Despite these minor concerns, I’m quite satisfied with this portable speaker. It has a great design, excellent sound quality, and offers versatility and portability at a reasonable price.

After a long time, I bought SONY again, and I really liked its new sound technology more than the other brands.
