Customer Ratings & Reviews

It’s obvious that you have a large selection of portable Bluetooth speakers out on the market. However, the Sony ULT FIELD 3 Portal Speaker stands out for various reasons. The first one being size. The size of the Ult Field 3 is approximately the size of 3 meat cans of Spam which makes it big enough to be the life of the party but small enough to be portable. Sony somehow packed a lot of sound and clarity into a package that will most likely travel everywhere I go from now on. The on-speaker modes of ULT1 and off seem useless. I don’t know why you would ever use the non-ULT1 mode of the speaker because the bass of the ULT1 is so smooth and perfect and not overpowering of the rest of the sound. Without the ULT mode turned on, the speaker seemed bland. However, with ULT1 turned on, it’s just amazing. With the slightly larger size, the battery is much bigger, allowing it to be powered for days. I have averaged 4 hours of Spotify streaming from my phone for a week and I barely hit the 50% mark of the battery remaining. I have no doubt that this speaker will last a week if you use it normally. Another thing that I originally thought was corny was the speaker shoulder strap. My first initial thought was it was ridiculous. However, after using it for the first few minutes, it has been around my shoulder all the time. I thought the wife would think I was being a dork, however even she thinks it looks cool being worn like a messenger bag around the house. She likened it to carrying a modern boombox around the house. Having worn it around the house, I sure have swung the speaker into walls, doors, and furniture and the speaker does not show one sign of wear. Although I would probably try to avoid swinging the bass ports at knives, the outer case is tough. I have additionally had the pleasure of spilling coffee on the speaker, and I rinsed under the sink the speaker and it is fine. I only did this because Sony claims IP67 waterproof and after accidental testing, it appears to be so. This furthers the claim that this speaker can go anywhere and everywhere you want it to go. Another feature that seems totally unnecessary, but I find using a lot is DJ mode in the app. While you are playing music, the DJ feature in the app lets you layer on top of the music sound effects such as clapping, drums, horns, and phrases. If you are at a party, you are essentially a walking DJ. One thing I do wish the speaker had been Wi-Fi-capable and casting features. It would be nice to play music without being connected to the phone so that messages and other sound sources on your phone would not be broadcast over your music. However, this would be a hit or miss to some people. By not having that Wi-Fi feature, this speaker seems future proof if smart features go out of style. Nevertheless, this is one of those speakers that has such good sound, incredible battery life, and great portability that it will end up being the most used speaker in the house and travel due to its versatility and ruggedness.

With Sony’s new ULT Field 1, it’s as easy as one, two, three from set up to listening to your favorite music! You can enjoy music playback. It is nice to find some tech that is so simple to use. There is a QR Code to scan on the packaging for a link to install the Sony App. Once the App is installed and is opened, select your specific Sony Speaker. I used Bluetooth to pair with the Sony ULT Field 1 from my cell phone with Spotify. I wasted no time in listening to my favorite songs and playlists. Great sound from a small “personal” Bluetooth speaker! • The battery life is 13 hours (kind of short for being such a small device these days). The ULT Field 1 gets its charge from a USB Type C port hidden in the back of the speaker. Unfortunately, the charging cable is what I would call, extremely short. This is a “minor” issue in my opinion because you have to be close to an outlet or USB Type A port. So, this takes up a lot of space on a desk. Even though this is inconvenient, it’s not bad as it seems because a lot of Bluetooth speakers have the same “problem.” I don’t like it, but it is not a make-or-break moment in choosing the Sony speaker. • I would say the Sony ULT Field 1 is on the lighter side of things while in your hand. This contributes to a rating of “IP67” which is protocol for being “waterproof, shock proof and dust proof.” It is also very sturdy despite its lightweight feel. When you like taking it on the go, there is a hand/wrist band that makes the ULT Field 1 easy to carry. • The Sony ULT Field 1 has really amazing all around surround sound for its size. Sony, using a “sound diffusion processor” basically allows you to hear music from all around while reflecting the sound off objects in the immediate area. This makes the speaker sound “larger” than its actual size. The ULT Field 1, has two passive radiators at either end of the speaker that move with the compression of air inside the speaker. It adds substantial bass to the overall music being played. The overall quality of the sound for this speaker is excellent for its small size. With the ULT button on, the music and sounds definitely take a step up in the area of substantial bass. When the ULT button is off, I think it is great for podcasts or anything that requires vocals or speech. You will definitely notice these differences right away, on or off, with the ULT button. I believe this is intentional and accentuates the sound for low frequencies (music) separately from high frequencies (vocal or speech). • Another added “touch” was the soft touch buttons that control the Sony ULT Field 1. You can access volume up/down, play/pause (phone call too), Bluetooth and power (which also shows how much battery life you have left). Add Pandora, Spotify or YouTube Music (I did not see Tidal) for your music streaming, or music you have downloaded on your smart phone, tablet or laptop/desktop. • While working on this review and listening to the Sony ULT Field 1, I received a phone call. So I pushed down the button play/pause which also answers phone calls. The microphones definitely did their job as I sounded clear, and bright to the caller. The caller in the same way sounded good to my ears. Sony did a nice job on this particular feature on the ULT Field 1. Bring your music with you all summer long! The ultra-portable ULT Field 1 Bluetooth personal speaker is a great companion for trips too. The sound is great for its size and the ULT button provides all the bass you’ll need to enjoy music.

I’ve owned several compact Bluetooth speakers probably about a dozen so far Which I used for Different purposes including bringing it to the beach, at home remotely or just remotely at work. I have to say this Sony Bluetooth speaker is hands-down the best Bluetooth small speaker for its size and weigh that I have owned so far. Set up took five minutes. The inclusion of an app with tone controls and customizing EQ is an added ability that My other Bluetooth speakers don’t have. I think the Bass EQ setting gives a very nice and surprising low end for such a small speaker. The reflex ports I think are doing some thing more than other Bluetooth speakers that I owned. I also found it nice and enjoyable to play with the EQ settings for a custom option. The app also informs you of battery levels. Also helps connect you to your music through Spotify And Amazon music, which I own and use and also connect very well to Apple Music via airplay. Yes, you can go directly into the Music app and connect directly to the Bluetooth, but I do like the added feature of connecting to the app. Additionally playing music in the sound quality I feel it is great. The volume levels can be adjusted so finally that it is appeared to my other Bluetooth speakers that I can get that perfect level, which is not too loud and not too quiet that other speakers can’t obtain. when all I think this is a great compact mobile Bluetooth speaker, IP 68 rating is excellent and you could take this anywhere including outdoors, beach, pool, etc. I definitely recommend.

The Sony ULT wireless speaker has been a great personal speaker with a long battery life. I use a personal speaker nearly every day to listen to podcasts, audiobooks, and music. I’ve used it for 5 days anywhere between 20 min to 2 hrs per day and have only needed to charge it once. The Sony Music Center app says it’s currently at 80% battery. A very practical feature that I enjoy about this Sony speaker is that it’s portable and waterproof so I can place it on the edge of my shower and not really worry about it getting splashed with a little bit of water. I can also hang it on a towel hook with the included strap. I like that it can sit flat or on its side, it’s basically the size of a water cup so it fits neatly on my desk. I feel that the sound is good, but more for podcasts and audiobooks than music. Even when the ULT bass boosting button was not turned on, the bass was a bit too much for me on the default mode. I went into the sound settings on the Music Center App to tinker with the levels and was able to get the speaker to sound a little more to my liking. While listening to some music, I picked up a phone call and enjoyed a clear call. This wireless speaker has echo-canceling technology and a built-in microphone. This was very convenient because I didn’t have to disconnect the speaker and when I was done with the call, I seamlessly went back to listening to music. The volume button seems like it has more levels of adjustment than my phone, so I feel like I can change the volume little by little, which I think is a great feature. Listening to podcasts and audiobooks means that the “next” button skips forward 15 seconds and I love that I can access that feature by double pressing the play/pause button. I think this is a great speaker for people who prefer an artificially bass boosted listening experience. This will continue to be my daily speaker for the foreseeable future because it has a ton of features that I do like and the battery life has proven to be long-lasting.

This is a portable speaker that can also take the place of a TV soundbar or a stationary home speaker. You can position it with the controls on top, or stand it on its end as space allows. A shoulder strap is included with the speaker, which connects and disconnects quickly through innovative hide-away top access. The stated battery life is 24 hours, and it charges with a standard USB-C charger and can also function as a battery source to charge other devices. Please note that the charging block is not included. The accompanying IOS or Android app allows you to customise the device functionality and sound. There is a battery care option that will limit charging to 90% capacity, an auto standby option with will turn the speaker off in 15 minutes if not used, and an auto Bluetooth connect that will automatically turn the speaker on and connect when a paired device is in range as well as a mode to extend battery life. The sound options include the ability to either prioritize the sound quality or a stable connection, which is useful if you have a source device that drops the Bluetooth connection frequently. Also included is the ability to detect surrounding sounds and adjust the speaker for the best quality output, as well as a customer equalizer and a ULT Power Sound mode that significantly boosts the bass output. This can be enabled by a dedicated button on the top of the speaker or through the app. The speaker will also connect to other Sony speakers to create a party mode, and the app has a DJ control that allows you to layer effects over the music via a touch pad. Sounds emulated are robot, drums, scratch, audience, voice phaser, reggaehorn, and a preset rhythm that can all be changed by sliding your finger on the device screen. There’s a listening history available that can be configured similarly to a playlist for specific times or activities. Plus, the speaker is rated IP67 to resist damage from water, dust, rust, or shock.

I have several Sony portable/party speakers and one thing they all have in common is stellar bass output. The ULT FIELD 3 continues that tradition in a highly portable size that will surprise you with the amount of quality sound you get out of a compact device. There are a lot of things to like about Sony speakers. They've been in the business a long time and offer high quality sound devices that, from my hands on experiences, blow the competition away. This size speaker is designed to fit a specific niche. Given the size of the FIELD 3, it will reside easily on a desk, shelf or countertop. To add more versatility, it can be placed in either a horizontal or vertical position. Given that the speakers are on either end, I suspected the vertical choice would really hurt the sound quality but, amazingly the sound is pretty much the same either way. That said, this speaker has BIG sound. Big enough to fill a good size room with sound. It can go incredibly loud. The ULT button cranks up the bass and presence of whatever is being played. It's possible Sony just included this as a button so that you can hear the difference between using the ULT and not, because I can't imagine anyone using the ULT once and not leaving it on all the time. The ULT does give the music a ton of punch and dynamic range. The controls on the FIELD 3 are nice and basic without any button that leaves you wondering “what the heck does that button mean?”. A power button (obvious), a Bluetooth button (also obvious), a Connect button for connecting this speaker to other ULT series speakers in party mode, a single transport button for play/pause/phone, and of course the volume + and – buttons. Oh and the ULT button, which you'll only press one time to turn it on. These buttons all have a great feel to them and are located on the top (where you'd expect them to be). Also on the top are the two strap attachment points. If you want to use the strap, you just need to pull each of these guys up, rotate them, and put them back in to expose the strap attachment points. The strap itself is heavy duty and adjustable. The hooks that slide in to the tie points are beefy and metal, without looking looking huge and drawing attention to themselves. It helps the hooks are painted the same color as the strap. Pairing was about as easy as it could possibly be. I turned on the FIELD 3, it connected automatically to my S24 Ultra. This is possibly due to the fact that I already have the Sony Sound Connect app because that's also used for all the other Sony speakers I have. As far as the overall appearance of this speaker, I like the size of it. It's very portable. I would say this is its' main strength. If I'm at home and outside, I go with one of my larger Sony Bluetooth speakers because they have better sound quality. But Sony has made a good portable here. The fabric on the main body is comfortable when carrying, and textured for a good grip. It also has an IP67 rating for water and dust which is perfect for pool areas, beach environments, camping situations and in general good for overall changing weather conditions. The color, I'm not thrilled with. Looking online, this speaker is shown in a very nice looking “Forest Gray” color, which looks like a cool sage green. Disappointingly, this is not how mine looks (even though the box mine came in says it is indeed Forest Gray). The color does seem to change in different lighting conditions, at times it seems like a richer gray color, but nothing I would call green. The online photos seem to greatly enhance the green color a lot more than I see in the real life edition. This particular unit does not come with any LED lighting which I'm totally fine with. On a portable speaker this size, it's completely not needed. If you're looking for the best sound quality in a wireless speaker, Sony has other, larger speakers that are better suited with this in mind. If you're looking for a highly portable Bluetooth speaker that offers way more bass than a speaker this size has any right to have, this is a really good choice. It took me between 15 and 20 minutes to charge from 60 to 100% using a 100W charger. Battery life seems respectable and none of my use cases drained the battery. Sony claims 24 hours of battery life which is probably reasonable, and it should easily last for a weekend camping trip no problem. You can also use the USB-C connection to charge a device like a phone. Even after visiting Sony's web page, I still can't explain what the “ULT” refers to in the name of this speaker series. Is it short for “ultimate”? Is it some acronym? I don't know! But it's in the name, and on a large button, so clearly it means something to Sony. For the sub $200 price, I feel that for that cost you're getting a really good speaker with great sound quality and top notch engineering that should allow this speaker to hold up for years of use.

I have had a chance to use this speaker for a bit now and i have to say it's a very nice sounding speaker especially at that price point. DESIGN The design is very simple and clean, the handle/strap is convenient and stays out of the way. It is small and easy to carry around. The finish is a nice rubberized matte finish and has a slip proof feel to it. It is waterproof and dustproof, i haven't had any issues with slight splashing from a nearby pool. It can be stood vertical or on it's side. SOUND The sound is very full and rich, like most sony speakers it is a bit BASS heavy and even more so with the ULT button to boost the bass. It fills a room and packs quite a punch with the added bass boost. It has 12hr battery life and easy charging with any USB-C cable. It is also easily controllable via the sony music center app. The bluetooth v5.3 has a very stable connection and and a pretty good control distance...I have been about 20 ft away and have not suffered any signal loss. Overall a very versatile speaker that is easy for on the go tunes and durable. A+

The Sony Ult Field 1 is a great portable speaker. It almost checks all the blocks that I want in a portable speaker, while excelling in a few areas. Aesthetics are outstanding, its a great looking speaker. It doesn't look like your typical BT speaker with a drum shape, the typical speaker mesh, etc. Its got more of a semi rectangular shape with a nice cloth mesh wrapping it. On either end of the speaker is a semi cone for channeling the base the little subwoofers pump out, and it has an almost useful rope on it for carrying around (albeit its more obnoxious than useful). If I could change something with its design (something I will be doing on mine) would be the rope. I will be removing that on mine and adding a carabiner to clip it on to my gear as opposed to dealing with trying to knot it on or dealing with buckles. Looks aside, the general build of it is also pretty good. The ends act as sufficient protection to the subwoofer cones, while also acting to help funnel the base out of the little device. The sound is almost omnidirectional out of it with the only exception spinning it on the ends with the actual subwoofers. If you do that you lose some directional sound. It doesn't sound bad, but you can tell its not centered anymore. Rotating it on the body though the sound doesn't seem to distort. I haven't disassembled it to see the configuration of the speakers but they do a good job of making it appear omnidirectional. This said, because of the subwoofers if you are not centered on the speaker you can tell when you're off center. This thing pumps out a shocking amount of bass for what it is, and because of that the sound can feel directional from that perspective. I haven't done a thorough battery test on this as I've only had it a few days, but so far its doing very well. I've charged it once fully after receiving it and listened to it for a full day at work and have 40% remaining. I didn't have it max volume the entire time, but for most of it I did just for testing sake. Because my unit came with an almost full charge (70%) I didn't get to test full charge time either. It didn't take long to get to 100% from there, but I wouldn't want to give an impression based off that short 30% charge. What I do find annoying, and its not exclusive to this, the amount of devices, especially those that cost more than $50 is the lack of a charger. This comes with a very short, cheap feeling charging cable. I understand that most people already have a charger, but it would be nice to get a semi decent charging block with a cable longer than 3ft so I didn't have to reuse the same charger that came with my one device that was nice enough to include it. Finally the sound on this thing is incredible. I'm no expert on portable speakers by any stretch. My experience is limited to a few JBL speakers that others have used at work and my own JBL Clip portable speaker. That said, the sound is on an entirely different level. The Sony ULT has great range which is greatly accented by its two subwoofers. It adds depth that I always found sorely lacking in other speakers. The subwoofers really come to life if you use the ULT preset (enabled by a button click on the speaker). This mode really increases the bass. Its kind of annoying as there is a transition sound turning it on and off, as well as a pause so you should probably just leave it on. Though in Sony app you can toggle it without the pause or tone. If you love bass in your tunes, this speaker is for you. The speaker comes with some other notable features such as being ruggedized. Its supposed to be used in the field environment, on beaches, etc. I haven't had a chance to test the durability of it, but given my line of work I wouldn't really say its 'field' but more 'sport'. I feel the mesh cloth and the open ends for the subwoofer would make it more prone to damage than more hardened speakers. I think this belongs more on the basketball court or in the shower more than out camping or fishing. But I haven't tested it yet so I can't really dock it on that, just an impression. There is also an app you can download that will let you change the sound profile with an equalizer. Its pretty barebones with only the Ult preset (which sounds the best in my opinion) and it can launch your music apps. Not really worth installing, but if you like to dial in your bass/mid/high then it might work for you.

I wanted a small speaker to be able to take with me anywhere. This Sony ULT field speaker definitely fit that criteria. I like that it has the ULT button on the speaker; as a bass and music lover I keep this button on! It honestly delivers ultimate bass; sound quality feels as though I have a home theater sound system in a smaller size with this speaker. The volume can be either high or low and it still can be heard/felt in such a powerful way unlike other speakers I've had. I like to have music in my kitchen, bathroom, anywhere in my home. I can enjoy my music whenever I shower! Yes, I love to have music in my bathroom as I shower and my Sony ULT field is indeed water proof; of course I don't have it inside my shower with me I have it inside my bathroom and listen as I shower. With all the moisture build up in my bathroom from taking a shower; I don't have to worry about my speaker getting damage. This speaker has passed the test and I love to be able to feel as though I am in a concert while I shower! I cannot wait to take this when me on the to when summer comes; to the beach, pool and not have to worry since it's waterproof. I've noticed that some speaker can get collect dust when they put in an area. However, my Sony ULT field is on a whole another level. I have not seen any dust accumulate no matter where I place it for however long unlike other speakers that I have had/have. That to me is a great thing! The multi strap makes it super convenient to carry anywhere. The strap is very sturdy and hold my Sony ULT field speaker very well. I don't have to constantly charge my speaker as the battery life last 12 hours. I have tested this and this is indeed true! I love that I can listen to my speaker for long hours and not have to worry about the battery quickly draining. Now, when it comes to shockproof I have tested this without trying. I mean my that is that I had my Sony ULT field a little too close to the edge and had it sideways and it ended up falling and it took me by surprised. However, the speaker keep playing music as of nothing and there wasn't any bumps and scrapes. I gasped when I saw/heard it knocked down; however, then realized how powerful my speaker is when I saw that nothing happened to it! This Sony ULT field is the real deal! I love that as I'm listening to music if a call comes in for me I don't have to switch to my bluetooth headphones. I can continue to speak through my speaker and the sound is super clear on my end and on the callers end. I downloaded the music center app when I connected my Sony ULT field speaker to my phone as well as my computer. It's a great app, it's easy to navigate. It helps to optimize my audio settings and to retrieve playlist from phone and computer. My Sony ULT field speaker has it all! As a music lover that likes to have my music everywhere I love this speaker it's multi faceted. I am super happy to have this and I would recommended it anyone that's is looking for a speaker with the criteria that this Sony ULT field carries.

The Sony ULT Field 3 is a powerhouse in a portable package. The sound is crisp, loud, and surprisingly deep for its size, with punchy bass that doesn’t distort even at high volumes. It’s perfect for outdoor hangouts, beach trips, or just vibing at home. The battery life is impressive, easily lasting all day, and the rugged, waterproof build means you don’t have to worry about a little rain or splash. Bluetooth connection is quick and stable, and the extra bass/ULT button gives your music that extra kick when you need it. Overall, the ULT Field 3 delivers rich, dynamic sound and durability in a sleek design—definitely worth it if you want a reliable and great-sounding portable speaker.

Overall a very good speaker. Pros Connects easily and maintains connection around my house Plenty loud for the house but probably not enough for a house party Battery lasts 8 + hours Build quality is great Cons Music quality or accuracy only ok with lots of muddy bass. Cost seemed slightly high for sound quality.

I purchased this speaker to augment my iPhone in social situations. I've found it very easy to pair with my phone and the sound it puts out is really outstanding - good bass and good treble. Volume is quite strong, too. The battery lasts a long time and recharging is very simple. I got an excellent price on this item; with some BB points and the customer discount, I got it for less than $70. Very pleased with my purchase.

Sony’s bluetooth speakers are always hit or miss for me. They often sound good, but are more expesnive than other brands while not sounding any better. Not the csse with the new Ult series. This is Sony’s new Ult rugged portable speaker. It’s rated for dust, water, and drop resistance. The built-in rope for clipping to things is a nice touch. The speaker gets loud and pumps out the bass when the Ult button is pressed. Battery life is ample and recharges via USB C. There’s not much more I can say about this great speaker.

Really fantastic battery life! I love the sound waves. It even sounds great on the ocean. The vibrant orange color makes the speaker easy to keep track of. The best feature really is the rope attached, which acts as a handle. I use a carabiner to hang the speaker up while charging and while listening, which works great on the go. Sony nailed this one! Price was right!

This is my favorite Bluetooth speaker I've ever purchased by far. It is SO versatile. I use it all day, everyday. The bass is uncommonly great for a speaker this small. Small enough to take on day hikes. Totally durable and waterproof. I kayak with it. I strap it to bikes and even a Vespa scooter. I can use it as a speaker for my computer. My favorite use is at night. I use it as the Bluetooth speaker for my bedroom TV. I hate using earbuds or headphones. I can put this on my nightstand right next to my ear, listen to an action movie with explosions and not disturb anybody in the house. If I am watching the news or a podcast on YouTube, I can take it with me to any room in my 1200 sq ft apartment to continue listening while cooking or cleaning & the range is fine. It's a great choice for apartments and dorms. It's loud enough and has enough bass to jam out in a small space, but you aren't gonna get a call from the landlord. With the waterproof feature, you can take it into the shower with you, which is the only place I sound good singing along. I love it so much, I'm thinking about getting a 2nd one, since it can be paired with a 2nd speaker for more stereo sound. It has INCREDIBLE battery life. One full charge should last you all day. I've looked at Bose, JBL and some of the other options. This is definitely the most bang for your buck. Great quality. Great all-around sound. I've had it six months and haven't noticed any battery degradation. You really can't go wrong.

This is a very solid speaker. It definitely has the "Sony sound". What I mean is after listening to lots of different audio products over the years, you start to hear their sound profiles. Sony has a very pop music centered sound. Punchy but not deep bass, sufficient mids, and good highs. Just really a "gets the job done" sound, but at a cheaper price than the big B's that do the same thing. Overall, it's a nice touch that the bass boost Ult button can disable the bass for listening to softer instrumentals and more detailed music. It never feels crisp, but always seems to feel "enough". It will sound good in a midsized room, but is boomy in a small room or bedroom. This absolutely hits the ball out of the park for a good beach or patio BBQ speaker. It can easily fill a decently sized patio space with music and if you party connect a few together, you can fill any size space you can think of. The IP67 rating will keep the components safe from water sprinkles, sand, dust, and smoke. It can get fairly loud before distorting. Overall, I'd say if you are into pop music, country, or rock, this will hit all your needs beautifully. When the rock anthems start to play, hit that Ult button and let the air guitar commence. If your music tastes frequently jump to the softer side of music... instrumental jazz, smooth jazz, classical, soft rock... this speaker might be too unfocused and boomy for you. It's somewhat adjustable via the phone app, but I couldn't get it to dial in tight enough for my liking for the softer music listening.

The Sony ULT Field 3 blew me away with how much sound it delivers for such a compact and portable speaker. The bass is rich and deep without overwhelming the mids or highs, making it perfect for everything from rap and EDM to acoustic sessions. It easily fills a room or backyard space with clear, powerful sound. Battery life is another huge win—it lasts all day without needing a charge, which makes it perfect for outdoor activities, travel, or just keeping around the house. The build feels durable and rugged, yet it’s sleek and stylish enough to fit anywhere. I also love how quickly it pairs with my devices and how stable the Bluetooth connection is. Overall, this speaker checks every box: portability, durability, amazing sound quality, and long-lasting battery. If you want premium audio on the go, the ULT Field 3 is a fantastic choice.

Initial Impressions: I pulled this out of the box with with high expectations being a Sony product and was not disappointed. The overall construction feels really solid - I.e. it will take a beating in my daypack or on a bike out to a camping site. I charged it up - That took about three hours so given the rated charging time ( 5hours ) I would guess it arrived at about 60 percent. The bungee style cord and fabric like covering both feel durable and are not likely to hold water. The rubberized surfaces are great and provide a nice grip. Connectivity: I connected this to iPhone, A New flagship model Android Tablet, an old android tablet and Windows PC. Pairing was simple and the device connected without issue to everything I tried it on. All newer devices were able to reconnect without issue. I always test this as I have had a few devices in the past that were just difficult, required re-pairing or had to otherwise be "rebooted". I had no such issues with this speaker. It worked as expected. Audio: Lows are especially good for a speaker of this size with the ULT feature enabled. Overall volume and clarity is excellent for a monoaural speaker that's the size of an energy drink. Clarity of voice for audiobooks and speech is very high with or without ULT enabled. This is an area that many small speakers fall short in - this one does not. Battery Life: I ran this in my garage with ULT turned off for most of the day, over a standard weekend. I left it on intentionally just to see how long it would last. It exceeded the rated 12 hours with ULT enabled by 5 hours and still had power left. This is about double the battery life of my prior Bluetooth portable speaker ! It's rated at 12 hours 50 percent volume with ULT disabled. The sound level at 40-60 percent with ULT should yield around 8-9 hours of playback which is more than enough for me. Buttons: The control buttons are recessed behind a rubberized panel and include exactly what is needed: Power/Pairing Mode/Play-Pause-Call End/Vol -/Vol +/Ult Boost What I love - Great for a conference / group call ! Rust, Dust and water resistance, overall tough design ! Room for improvement - The included travel charging cord is incredibly short. I would prefer one 2-3 times the length.

The new Sony ULT Field 1 Bluetooth speaker is Sony Corporation's new entry into the crowded arena of small portable Bluetooth speakers. Is it worthy of your consideration? Sound: This speaker packs quite a punch for it's size. The ULT sound button increases the bass response of the Field 1 quite a bit, but not at the cost of decreased treble. I think it has a very pleasing sound quality, especially at lower to mid volume levels. The bass response is slightly reduced at higher volumes, which is pretty typical of all small speakers. Build Quality: The design and construction seems to be well done and this speaker should be able to stand up to the stress of daily use quite well. The two side mounted passive radiators are protected by solid feeling endcaps, which I believe are rubber coated. I like that the included sturdy strap is removable if desired. I don't plan to get this speaker wet, but it's nice to know that it is protected from accidental spills and drops. Sony app: This speaker doesn't require an app for connecting to a phone or tablet, but the Sony Music Center app is helpful for firmware updates and for it's equalizer function. By the way, connecting was simple, with no issues for me. The Bluetooth seems fine. I have not experienced any sound dropouts or lost connection issues around my apartment. Call quality: No dropouts, but slightly muffled. I would call it fine overall. No problems in conversation. Things I don't like: Mono speakers are not my preference, but I still like this speaker since it can be positioned upright and horizontally with no difference in the sound. I do plan to purchase another of the ULT Field 1 to make a stereo pair in the near future. Conclusion: Would I recommend this speaker? The answer is a definite yes. If you are looking for a portable Bluetooth speaker that pack a bass punch above it's weight class, then I believe you won't be disappointed with the Sony ULT Field 1.

Gets loud, good design, great battery life, and type c charging. Bass performance is good, overall I would say it sounds good/acceptable. You can kind of tell the distortion rate is high and sound separation is mid. I got it on sale for $150. For full price may be disappointed, but at $150 go for it.
