Customer Ratings & Reviews

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.

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.

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

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.

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.

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 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.

Great Solid build quality Includes carry strap Clean attractive design Straps attach very securely IP67 water rating Clear vocals Can be linked with other Sony speakers with party mode Can connect to a second Field 3 for stereo mode Surprisingly good as a speakerphone in calls Supports multipoint Bluetooth USB-C charging doesn’t require special cables Custom EQ option Battery care option extends battery lifespan Works well for resonating bass Works as a power bank to charge your phone Good battery life Not so great Occasional Bluetooth stability issues when using Prioritize Sound Quality Sound can be a bit boxy Attractive white design also shows dirt easier No stereo jack EQ doesn’t offer as much bass as Ult Mode Straps are hard to remove once attached Turning off ULT mode seems to turn off all bass The Sony ULT Field 3 has a simple, clean design. The finish of white textured cloth looks elegant, but over time it will likely collect dirt quicker than darker colors. In the box are the speaker, carry strap, and USB-C charging cable. The speaker feels solid and well built. It has a slight heft to it but is not excessively heavy. The included carry strap almost feels overbuilt and includes metal clips on the ends to attach to the straps on the speaker. The strap attaches via straps hidden behind rubber plugs on the speaker. The clips are easy to install and stay secure very well. However, removing the strap is more challenging due to barbs on the clips. While difficult, it does mean they are unlikely to ever come loose accidentally. There is a USB-C charging port and battery mode button behind a rubberized door on the back of the speaker. The battery button is for changing battery care mode and checking battery charge status. When care mode is enabled, it stops charging the battery at 90% to extend the lifespan of the battery at the cost of some runtime. There is no stereo jack, and playback is only via Bluetooth. The speaker supports party mode where it can be connected to other compatible Sony speakers. I do not have another to try this feature out. For setup you can connect as a standard Bluetooth speaker without the app. However, the core features of editing Bluetooth connection profiles and creating custom EQs will not be available. You also lose the DJ function. For Android phones you can pair via a quick tap on the speaker. If you have a second Field 3 you can connect them as a Stereo pair. You can also connect it to other compatible Sony speakers with Party Connect. First, with the ULT mode off it sounds as if the speaker has no bass at all. It can save battery life but would drastically reduce the quality of music. One place where it could be useful is if you are listening to podcasts or other speech as the bass doesn’t matter. In ULT mode the speaker is surprisingly good at producing resonating bass such as what is produced by a bass guitar. No surprise that it struggles to reproduce punchy bass with its small woofers. The overall sound is clean and precise even at high volume with no perceivable distortion. Vocals are crisp and clear, slightly bright, but not harsh. The sound is also slightly boxy but not over the top. The sound is very directional and you can tell exactly where the music comes from. From a distance, it sounds more like you are standing in front of a stage with the performer versus being in an auditorium. If you are thinking of using custom EQ to try to tweak out the boxy quality, you will find it comes at the cost of bass. While Custom EQ does offer 7 bands, it seems as though Sony has opted to limit the maximum bass to the preset ULT setting. It’s a bit of a shame as it would be nice to have the extra tunability. That said, most people would like the standard ULT profile as it makes the music feel lively and lets the vocal stand out without being offensive. Periodically while using the speaker, it would start to have issues with having a solid connection to my phone while playing music causing stutters. This is the Bluetooth profile that favors audio quality. While I could have changed Sony Connect to use the profile that prefers connection stability over audio quality the issue was not very common. It might seem strange for a Bluetooth speaker to offer speakerphone capability, but it comes in handy. If someone calls while you are listening to music, you don’t have to worry about stopping the music or disconnecting from the speaker. You can answer the call straight from the speaker and the music is paused automatically. Audio quality from the person speaking was clean and clear and people reported the echo cancelling mics sounded good. They said it sounded like a good quality speakerphone. It did pick up some background noise but not enough to interfere with the call and it made talking on speakerphone feel more natural than on the phone itself. Part of the reason is the voice of the person you are speaking to sounds far higher quality than the little speaker built into the cellphone. It seemed like a gimmick at first. It may not be required but it is surprisingly nice to have. Overall, the Sony ULT Field 3 is a solid small portable speaker and the departure from the flashy speakers from the past is appreciated. If you are looking for a small to midsize portable speaker the Field 3 is worth considering.

This Sony ULT Field 3 portable bluetooth speaker has amazing sound, long battery life, convenient features and is rugged enough to keep you entertained at the beach, by the pool when washing your car or anywhere else where it might get wet or dirty. Highlights: * Easy power button- tap on, tap off. * Amazing sound for its size. * Great battery life (up to 24 hours) and quick charging (10 minutes for 2 hours). * Completely dust-proof and splash/water-proof. * USB-C charging. * Convenient detachable shoulder strap. * Useful features in the app. * Can synchronize multiple speakers for larger, wider sound. Room for Improvement: * ULT button is backlit when on but its iridescent label looks on when off, too. * Have to open a sealed door to charge. * An additional shorter strap would be nice for hand-carrying or hanging. * Battery status should be announced when turning on of off - currently have to open the sealed door and press the button to hear the battery level. Setup: Like most speakers of this type, setup is basically two steps; charge it up and then pair it via your device’s bluetooth settings. Unlike many other BT devices, the power button is a simple tap on, tap off versus having to hold it to turn on or off, which is both different and more convenient. You can optionally install the free Sony Connect app to see live battery status, adjust various settings, use a DJ mode to apply sound effects on top of the music and update the speaker’s firmware when available. Usage: Once charged and paired, it works like any other similar device. The bass radiators are either side and the main speakers fire out of the front, so you can position it on its bottom (sound forward and wide), on its back (sound up) or on either side (sound forward but tall). In addition to the dedicated power button, there are distinct buttons for volume up, volume down, play/pause/answer/end, Bluetooth/Sync pairing, connecting to other compatible speakers, and turning the ULT sound tuning on/off. There is audio feedback when turning the speaker on or off, but there is no battery level display. To see how much power is left, you have to either connect it to the app or open the charge door on the back and press the Battery button to have it speak the battery level. I think a useful improvement might be to speak the power level every time you turn the speaker on or off. That way, you always know how much power is left without having to do other stuff. There is a small LED above the power button (to indicate when the speaker is on), above the Bluetooth button (to indicate when the speaker is connected or pairing), above the Connect button (to indicate when it is connected to other compatible speakers to sync the music), and the ULT button (for when the ULT sound tuning is on). Unlike all the other buttons, the ULT button is flat, shiny and has the ULT logo in an iridescent color that almost looks on even when off. There is an optional setting to have the speaker remain in standby so that when your phone (or other supported music device) starts playback, the speaker will “wake up” and start playing the music. Otherwise, you have to turn on the speaker first. This optional feature is convenient but it does reduce the overall battery life of the speaker. The included carrying strap has substantial metal buckles that fit into looks on the top. The loops are behind a cool tab that is normally flat and unobtrusive but can be rotated to allow a loop out that connects with the strap’s buckles. The strap is long enough to carry the speaker on your shoulder or hang it from something like a tree, but I’d also like a shorter strap (this one doesn’t get very short even when adjusted) to carry the speaker by hand more easily. By the way, the buckles do come off if you need to remove the strap for cleaning or anything else, but it is a tad tricky to get them off (by design, I’m sure). The optional app shows the current battery level, allows for firmware updates when available, and has various other settings. There is a setting to either prioritize sound quality or bluetooth stability. When prioritizing sound quality, the sound is really epic, but you really need to keep your source device close. I had mine about 10 feet away with some metal in between and the audio kept cutting out. Even when set to prioritize Bluetooth stability, the sound is truly amazing so you can’t go wrong either way. There’s even this interesting “DJ” feature in the app where you can use your phone’s touchscreen to add sound effects on top of the music that’s playing. Scratches, voices, various sounds, etc…. Not sure I’d use it often, but it was fun to play with for a bit. With the built-in microphone, you can accept speakerphone calls on this and they really sound amazing. Great for a group of people to get on the call! The entire speaker is IP67 rated. This means that with the battery flap closed, it is essentially impervious to sand, dust and dirt. Still with that door closed, you can submerge the speaker in water up to 3 feet deep for up to 30 minutes. Get it dirty or wet with saltwater? Just hose it off and let it dry. I tried some electronic music, classical, jazz, R&B and Americana music - all sounded nuanced and clear with emphasized bass that didn’t overwhelm. Overall: This speaker truly sounds amazing, has great build quality, useful features, and is rugged enough to use just about anywhere.
