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.

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

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.

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

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.

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

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.

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.

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.

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

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.

The Sony Ult Field 3 is an impressive portable speaker that packs a good amount of bass in a medium sized package. I picked up the Ult Field 3 because I have the original Ult speaker from Sony and really enjoy it. The only real downside I had from the first one was it could have been louder (especially at work sometimes). So seeing a bigger Ult speaker enticed me. Quick rundown. Pros Great sound quality Good Bass for a portable speaker Waterproof Comes with a should strap (though I never used it). Great Battery Life Decently Loud Cons Bass peaks at about mid volume The build quality on this speaker I've come to really like. It has rubberized buttons and a cloth like knitted material all around it. The USB-C port has a rubber seal to keep it protected from the elements. The weakest part of this design I believe is the ends where the subwoofers are exposed. These could become damaged, but they do their best to protect them by having them sunk into the case. It comes with the typical buttons you would find on a BT speaker, but also a connect button that lets you daisy chain them together. I haven't got around to using that function yet though. The sound quality on this thing is pretty great after it did a firmware update. At first I was a little underwhelmed, but after installing the Sony software on my phone it pushed a firmware update to it and the sound became much better. The bass on this pretty good up to medium volume. After that though it becomes pretty flat while the mid/highs outpace it. Its not bad, but its noticeable that it doesn't scale as well as the rest of the range. Still very happy with the sound quality and how loud this thing is. Battery life on this is great. It lasts a full workday (so 8-12 hours), and I simply charge it when I get home. I'll have somewhere between 20-40% battery life at the end of the day. The software is pretty good. It has been updated since my first Ult speaker. Now it has full EQ control, some battery saver features as well as other miscellaneous things. Overall very happy with this speaker and look forward to what they produce next.

Sony ULT FIELD 3 is a powerful portable wireless speaker. While it leans on the larger side at 10 inches long, it's surprisingly lightweight and easy to hold in one hand. The adjustable shoulder strap enhances its portability, making it convenient for on-the-go use. Designed for durability, it boasts an IP67 rating for water and dust resistance, giving me peace of mind when using it outdoor. Straight out of the box, the sound quality impresses with punchy bass and crisp highs. The ULT (Ultimate) sound mode adds extra depth to the bass, though it can sometimes overpower mids on bass-heavy tracks. Bluetooth connectivity is seamless - once paired, the speaker instantly reconnects when powered on. The built-in microphone allows for hands-free calls, adding to its versatility. The top control strip includes dedicated buttons for play/pause, volume adjustments, and the ULT mode, which lights up and changes color when activated. The recessed strap connectors are cleverly designed; they sit flush with the speaker when not in use, maintaining a sleek aesthetic. With the Sony Sound Connect app, users can personalize their listening experience using a 7-band customizable equalizer and also enjoy DJ control effects like robot sounds, vinyl scratching, and reggae horn effects. Battery life is remarkable, promising up to 24 hours of playtime, an estimate that feels entirely realistic after using it for a few days. Charging is convenient via USB-C, and the speaker doubles as a power bank for other devices. Overall, I am happy with this speaker.

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.

This Sony ULT Field 3 Portable Speaker is more than just an ordinary portable speaker. This speaker is indeed an awesome little portable party wherever you take it. I am extremely impressed with this little portable party. In the box: You get the Sony ULT Field 3 Portable Speaker (black, grey, or white), shoulder strap, cable, documents Setup: Setup was extremely easy. I downloaded the Sound Connect application and connected to Bluetooth. I take full responsibility Features: The ULT button is cool. It turns on the Bass boost. On a standard sound meter, the dB went up by about 10 with the ULT button on. That varied with the song of course, but that is an average. Party Connect allows you to connect a maximum of 100 compatible speakers together for synchronized sound. I connected 4 speakers together and it’s truly amazing! Stereo Pair allows you to connect a second Sony ULT Field 3 for true stereo sound. This sounds amazing. I did this and love listening this way. The shoulder strap is a big plus. It allows one to carry the speaker around regardless of how you travel, be it on foot, bike, skateboard, scooter, etc., it just makes it easier to carry. IP67 rating broken down – the 6 means dust protection and the 7 means protection against water immersion up to 1 meter or 3.37 feet for up to 30 minutes without damage. This Sony ULT Field 3 is dust proof, sand proof, rust proof, and shock proof. So, if you accidentally knock it up against something as you are walking, you will not have to worry. Battery Life and Quick Charge are amazing. Sony ramped up its game on this one. The battery life is up to 24 hours on a full charge. You can also get 120 minutes or 2 hours on a 10-minute quick charge. 7-band equalizer is completely customizable in the Sony Sound Connect application. Phone calls are great on this too. You can clearly hear the other party and they can hear you clearly too. I had no issues at all with call clarity. Sound Connect Application has a DJ mode that is pretty awesome. I played around with it and was able to add some really cool DJ effects to my playlist. Adding robot sounds, scratching, and intros. It’s something you have to try even if you don’t DJ. Summary: I will get a lot of use out of this Sony ULT Field 3 speaker. The sound is great and I love the application and all you can do with it.

Like my favorite food, I can never have enough Bluetooth speakers. More than a dozen are strategically placed throughout the house, from a pint size one to a giant 1200-watt party speaker and every size in between. Here comes the Sony ULT Field 3 to the family, and I can’t help but love it for its nearly perfect size and impressive sound quality. At 10 inches wide, a little over 4 inches tall, 3 inches deep and weighing about 2 and half pounds, the Sony ULT Field 3 comes close to the ideal portable speaker. First, it feels well built with smooth rounded lines that exude Sony quality, and so is the texture of the enclosure. It looks rugged and modern and, thanks to its small size, it can be placed almost anywhere. Connecting it was an easy process through Sony’s Sound Connect app. It’s a simple and easy to use app, with the ability to connect multiple speakers at a time. Several modes and features are available through the app to customize the speaker. I tried several of them but one of the most useful ones, the Bluetooth Standby mode did not work for me. This gives you the ability to turn on the speaker directly from the app after turning it off. It turns off from the app but won’t turn on. I own another bigger ULT Field speaker and that feature works flawlessly. I’m positive a future update can correct this issue. Now for the sound. Sony ULT Field speakers are known for their powerful bass, and this small guy doesn’t disappoint. For its size, the bass delivery is impressive. From Hip Hop, Country, Jazz, Latin and Afro Beats music the bass never lets you down. The mids and highs are good enough to keep up with those dynamic lows. It can also play loud enough to fill up a sizable room. The battery life is a welcome benefit of the ULT Field 3. Sony claims up to 24-hour battery life. I believe it’s possible, however you have to switch to Stamina mode that removes most of the lows and trims the highs a bit. The sound quality suffers. On the ULT sound mode and at a generous volume, I easily played continuously over 4 hours without a hitch with plenty of charge left. You can customize the sound with a manual equalizer but I quickly ran back to the ULT mode which made everything else sound a bit underwhelming. A feature that adds to the ULT Field 3’s portability is its dust and waterproof ratings. With an IP67 rating, it will resist dust and water effortlessly. You can take it practically anywhere and the addition of a stylish shoulder strap is a great enhancement. A day at the beach, this speaker played all day in the sun, sitting in the sand, and handled the occasional splashes of water with ease. I’m truly impressed with Sony’s ULT Field 3. I wasn’t expecting such a good performance. With the thoughtful addition of the shoulder strap, it’s small enough to carry around and powerful enough to deliver hours of entertainment with quality sound. It comes close to being the perfect portable Bluetooth speaker.

I received the white Sony Ult Power Sound Speaker. Set up was a breeze. I turned on the Speaker and it immediately began a search. And it displayed the color of the speaker with the words Ult Field 3 and showed it attempting to connect. I followed the prompts and was good to go. I began testing the speaker with watching videos and movies online. The sound was pretty good. I could hear the bass. On certain songs, the bass was slightly muffled. However, the majority of the songs, I played could hear the base very well. I watch many videos and the sound clarity came in good. I tested it indoors as well as outdoors. When indoors I went to the living room, kitchen, den, dining area, bedrooms, and no matter the space, the speaker provided could sound. I love the fact the speaker has a strap that can be carried on your shoulder. The majority of the speakers I own, they come with strap, but don't have the connivence of the shoulder strap. Thank you for having the strap! The speaker lasted me over 24 hours. Your able to connect it to other sony's. I will test this if I every own more than one. I was happy to test this product. This will definitely be following me to the park, on outings', the beach, desert areas, mountains, etc. Thanks! Pros: The Strap! Great Sound Portable Water resistant Dustproof Cons: None at the Moment
