Customer Ratings & Reviews

TLDR: Sony packs a lot of sound in a small package. Combining 2 tweeters, a mid-woofer, and 2 passive radiators, the ULT 5 has big sound. PROS ULT produces big, punchy sound Higher bitrate LDAC support for Android devices Easy to use Sony Connect App CONS Sony relabeled Mega-Bass to ULT USE The new ULT 5 speaker is an evolutionary step in Sony’s party speaker lineup. Sonically, it is almost identical to its predecessor, which I reviewed at an earlier date. Not that it is a bad thing. Sony changed the look and form factor while retaining what made the prior generation appealing. The Sony Connect App has evolved over time and is quite easy to use and understand. It is your central interface for the ULT and prior generations. Firmware, lighting, DJ effects, equalizer, Bluetooth connections, and streaming services are readily available on 1 easy to understand screen. Even on a phone, the Connect App is simple and well laid out. Much easier than most of the competition. I have complained in the past about Sony’s issue with what I refer to as digital hiss. Not being able to pinpoint the source (amp or Bluetooth) Sony speakers exhibited this trait while in standby or during quiet passages in or between songs. For a long time, I didn’t recommend their products because of this. I am happy to report that the issue has been resolved. The new ULT 5 doesn’t suffer from this issue like previous generations have been plagued with. Quiet passages and between tracks are now silent, just as they should be. Thank you for listening to my complaints Sony! The Connect feature makes the ULT 5 easy to link to other Sony party speakers. With a simple button press, the ULT 5 can be synced with other Sony speakers making for a seamless listening experience. Numerous speakers can all be linked together to have music reproduction in perfect sync. It is slick and works extremely well, taking all the headaches out of trying to Bluetooth to multiple speakers at once. The ULT 5 sports a generous sized battery, good for up to 25 hours of playback before charging. Even at moderate listening levels for several hours, the ULT 5 has barely come down in charge. 25 hours seems achievable. Additionally, the ULT 5 is also IP67 rated against dust and water infiltration. A must when you have a party speaker at the pool. You can take the ULT 5 with you wherever you go and not have to worry about running out of power or having water or other environmental elements ruin your fun. NEGATIVES I am thoroughly bummed that Sony has done away with Mega Bass. For decades, it has been a trademark of Sony products. MP3 players, speakers, even old Walkmans, CD players, etc. All had a Mega Bass function. It is synonymous with Sony. The ULT button on the ULT 5 does the EXACT same Mega Bass does, just now with a different name. It is a shame. The nostalgia is gone. FINAL THOUGHTS The Sony ULT Field 5 is a worthy upgrade to the Sony party speaker line. It has good sound, lasts up to 25 hours on a charge, and is IP67 rated against dust and water. Whether it be at the house, lake, pool, or backyard, the ULT 5 is a great option. Easily connectable to other Sony party speakers should you need more sound and volume, the ULT 5 is fun speaker that should easily stand up to the rigors of a party environment. RECOMMENDED

Out of the box - It took me about 5 minutes to set up the Sony app and to get the speaker linked to my phone. The box lid had a QR code to scan which made navigating to the app and set up very easy. When I turned it on, the speaker had 60% battery life. It charges via a USB-C cord that came with it. Sony says it allows for up to 25hrs of play time on a single charge. While I have not tested it for 25 straight hours, I did have it on for 4 hours while painting my house and with the lights on and sound mode on Ult 2, it only reduced 17% in battery life. I thought that was impressive! On the back of the speaker, there is a USB-C port that allows you to charge your phone if needed which was a huge plus for me! I love an all in one unit. This speaker has some weight to it. I was pretty surprised for its size but with the should strap, carrying it around was fairly easy. The lights have a few different modes which can be switched in the app or on the actual speaker there is a button that allows you to change how they appear. My favorite of the bunch were the wave effect and the beat effect. Having the party light feature just adds to the fun of the speaker but they also can be turned off to preserve battery life if needed. Sound quality - the music and words were very clear and the bass, in different modes (Ult 1 and Ult 2), definitely changed in tone. I preferred the sound of Ult 2 for sure but during a gathering where the speaker would be on for a longer amount of time, I would most definitely use Ult 1 to preserve battery life. In the app, you can also customize the sound with the equalizer feature but that’s way above my head, so having the Ult 1 and Ult 2 modes work best for me. When the music is playing, if you hit the Ult button it makes a noise which cuts out the music. This notification can be silenced in the app if it’s a bother but it lasts only a split second and your music is back to normal volume. This speaker has a IP67 rating making it waterproof and dustproof. I think overall that’s the ultimate feature to have for having a portable speaker by the pool or when outdoor in general. Nobody wants a speaker that you have to baby. This one allows you to be in any setting without worry of hurting it. The Party Connect function is great! I have the Sony XV900 party speaker as well. With just a push of a button, I was able to connect them both and had the bigger, XV900 party speaker on one side of my deck and the Ult Field 5 speaker was approximately 22ft away. There was no sound quality loss, the words of the music were still very clear. Sony claims you can connect up to 100 of these speakers with party connect together. I cannot even imagine doing this, but man, I bet it would be so awesome! Haha. This will definitely be a great combo for us for our summer cookouts this year! Over all, this speaker is a win for me. It has a great price point for the features offered and Sony makes good stuff. You can’t lose, just buy it!

The Sony ULT Field 5 portable bluetooth speaker has exceeded my expectations in build quality and sound quality. It's also very aesthetically well designed. I have owned many bluetooth speakers and I feel the size, sound, and quality of this speaker is the perfect balance. The lighting, although not something I was directly looking for in a speaker, is a nice addition. Key Specs: Dimensions: 12.6” x 5.67” x 4.92” Weight: 7.28 lbs Battery Life: Up to 25 hours ( has a 10 minute quick charge which provides approximately 100 minutes of playback) Water/Dust Resistance: IP67 Rated Connectivity: Bluetooth 5.3, AUX input, USB-C in/out Speakers: 1 Woofer, 2 tweeters, 2 passive radiators Sound Modes: ULT1 (deep bass), ULT2 (powerful bass), 10 band eq via Sony Sound Connect app. My first impressions when I unboxed the unit was “Wow, this is bigger than I imagined it would be.” This is not a negative, I just wasn't expecting it to be as big as it is. It has quite a bit of weight to it as well. One thing that really stood out was the included shoulder strap. The buckles on the strap that you connect to the speaker are heavy duty metal. Like, really heavy duty. It may not seem important but what it did was highlight the quality of the materials. The speaker is wrapped in a very nice heavy duty fabric as well. Setup and connectivity was simple. Power it on, press the bluetooth button to enter pairing mode and connect to the bluetooth device listed in your bluetooth device list. It was simple. You can also download the Sony Sound Connect App which offers some additional features and customization options including different lighting options and the 10 band equalizer The app is nice to have, easy to understand and navigate, and offers another method of adjusting settings on your speaker. The sound quality is amazing. Both the ULT1 and ULT2 modes are great and depending on the type of bass you want, you have options. If you don't prefer the ULT modes, you can always customize your sound with the 10 band equalizer within the app. This speaker gets LOUD. But it gets loud with no distortion which is fantastic. This speaker puts out fantastic balanced sound that is loud enough to fill an area with quality sound pretty much anywhere. I can say enough how beneficial the included strap is with the speaker. It's adjustable and gives you the ability to bring it anywhere, hang it pretty much anywhere, and is a perfect addition to keep the speaker ultra portable. I hang it in my 3 car garage when I’m in the garage working and it's such a perfect speaker for the space. I also like how you can either lay the speaker horizontally or vertically which opens up options if you're limited on space. Battery life seems very good. I haven't had any concerns, even at fairly high volume and with the lighting effects on. I think that you could likely squeeze more battery life out of the unit if you turned the lighting effects off, which you can do. All in all, I have no complaints about the battery life and for my usage, I can go quite a while without needing to charge the speaker. Overall I think this is a fantastic speaker and I am very impressed with the quality and sound projection. I almost forgot to mention that if you have two of these speakers, you can link them together in a stereo pair. I would highly recommend this speaker if you are looking for a speaker you can take pretty much anywhere and know it will be enough to not just fill your environment with sound, but fill it with quality sound.

It's difficult to stand out in the world of bluetooth speakers these days, there's many, they each have special features or are at a price point that makes them enticing even if they are barebones. Sony, however, has managed to make something a little interesting. Packaging: To start, packaging is relatively straightforward, that said, it's nice to see that the speaker itself is in a cloth bag inside, kind of a touch of class to the standard packing experience, no plastic wrap or anything. Minimal literature and a small box with the USB cord and shoulder strap. Setup: Turning it on and having it near your phone results in a popup asking to connect to it. Yes this isn't necessarily a new feature but it's one of those ones that makes something tend to stand out as being a little 'higher end' than your average bluetooth device. That said, I've struggled with those popups in the past on previous devices, so it remains to be seen if it repeatedly pops up for no reason on other nearby devices after it's already been paired to one. As far as physicality, there is a flap on the back that covers the ports for charging and external audio input, nice to have especially if your source isn't bluetooth capable. It's the little extras that stand out on this. Use: Pairing is simple as stated, and once you get it rolling, the experience is nice. I will say the bass is a little heavy handed, though that can be toned down a little if you turn off the ULT button. Colorization moves with the music, equalizer and colors can be managed in the sound connect app, so all in all you can really customize this to an experience you prefer. It has faithful reproduction of sound with a little tiny bit of tweaking, and gets very very loud. I honestly have yet to run the battery down, that's how long it lasts, so you wont feel like you have to rush it to the outlet after every use. The shoulder strap is interesting, it connects through little rubberized popouts in the top, likely to help maintain it's IP67 rating. The strap is nice because honestly it's reasonably heavy, and not only that, it's rounded everywhere, so there's no real great way to hold it if you dont intend to set it down. Overall: It's fun, gets super loud, the lighting is great, the equalizer settings are good. If you're in the market for a portable loud bluetooth speaker with some fun extras, it's definitely worth it.

For its size and specially paired with that cool strap, this new Sony ULT field 5 can turn up anywhere. Either you want to bring it for a work-out session or by the pool, for your outdoor cooking etc. This speaker it's easy to carry, it offers long lasting playing time (25hrs battery life) and can handle any room or situation. I was impressed that for its rather small size this speaker comes in pretty hefty with an amazing powerful bass that can be turned off/ Ult1 / Ult2 (i personally like the Ult1 setting). The setting that i like and use the most **Ult1** offers a deep low frequencies and i don't even have to mess with any other adjustments since it works in any situation and outputs a clean sound! I also like that you can lay it flat or make it stand and the colors are vibrant and add to the party atmosphere (i always keep them on they are very pleasant). With a fast charging feature and an ip67 rating this speaker it's worry free that you'll run out of power or to make you nervous bring it some places. Ot can really follow you in any situation and entertain for an extended period of time. The Connection it's Flawless every single time and the connect button let's you inter-connect multiple speakers, i still have to see that in action, but that it can be super cool for stereo applications or using it at home for multiple room play, it is a very good feature to have and will be useful in many situations. I recommend downloading their SoundConnect app for a max experience and just go have some fun with it, it's a very capable little yet powerful speaker!

This speaker is absolutely wonderful. It can be used in both small places and even large gyms and spaces. It has extraordinary sound and even multicolored lights. My only warning to others is that it is pretty heavy compared to other small speakers that I have had and I usually have other equipment. I’m carrying with it, it definitely is better than a giant Speaker so it carries the same function so that is wonderful but if you are carrying it on a daily basis to and from classes or events it just is a little heavy. I also tried many of the other lighter ones and they do not carry the same volume. Newer cover the same square footage for sound as this speaker. Oh also the battery life is pretty amazing. I haven’t seen it ever get close, but it has 25 or so hours of playtime depending on what you’re doing with it.

Today I offer my thoughts on the Sony ULT Field 5 Portable Speaker. I’ve used MANY portable speakers over the years – and the first thing you’ll notice on this one is the weight. It’s a beautifully compact and stylish design, but the magnets and battery (along with a quality build) definitely make this speaker solid and hefty! I have a Sony ULT 7 speaker as well, which is a bit larger and even heavier – but this compact ULT Field 5 really produces a sound comparable to its bigger cousin. The Field 5 has a dedicated Connect button making it easier to pair with other compatible Sony speakers and unfortunately the ULT 7 doesn’t have this button and I couldn’t get the two to pair together for Party Connect. In the past I’ve used Party Connect with other Sony speakers and it was also a bit flaky to connect up. This is the main reason for the loss of a rating star. Sound wise, this compact speaker really packs a punch. With two bass modes ULT1 for rich bass sounds and ULT2 for more aggressive, punchy bass, you’re able to switch to your personal preferences easily or just change it with the music! The Sony Sound Connect app is your gateway to more settings – like controlling the lights, updating the speaker’s software, access to a customizable equalizer and more. Definitely a must have for better control of the speaker. Built with an IP67 environmental rating, you don’t need to work about taking your speaker to the pool, beach, lake or camping. It’s even saltwater resistant – so just carefully rinse it off if the tide comes in to quick and surprises you. A decent battery life of 25 hours is touted, but that depends on your sound levels, light usage, etc. If you run out – just a 10 minute quick charge can give you another 100 minutes of play time. Overall – I like it. It’s smaller size and weight will make this my go to campfire speaker. Probably a little to big and heavy to take on a plane, but if I’m driving to a vacation – this is coming with!

[PROS] Gets Loud: A portable speaker this size needs to get loud, and the ULT FIELD 5 definitely does that. I've found myself using the massive speaker on the outside patio and in the homes of friends. It gets the job done in making sure everyone can hear everything. Considerate Design: The speaker is large as intended, but very portable because of the included strap. It includes the basic ports, but the USB C port can also charge other devices as well. Furthermore, there's a shield protecting the inputs and buttons which comes in handy for places like the beach or park. Finally, the IP67 adds to the durability for dust and rain (although I'm highly unlikely to keep the party going if it starts to pour). Easy of Use: Everything that I desire to accomplish with this speaker is pretty straightforward. I was able to tweak EQ settings, adjust lighting effects, and update firmware without any hiccups. The Sony Sound Connect app is lightweight and simple to use. [CONS] Flat Sound Profile (Out of the box): My biggest critique of this device is that I feel like EQ adjustments are necessary. This doesn't apply to all genres. However, the bass is dependent on the ULT modes, specifically ULT 2. Otherwise, the speaker is not as punchy. In my opinion, the ULT modes make everything sound better so I usually just default to using it instead of fiddling with settings. [CONCLUSION] The ULT FIELD 5 is a well rounded speaker for my needs. It's loud, entertaining, portable, and pleasant to use. It's become a party favorite in my household, and I look forward to much more future usage out of it.

I bought two of these Sony speakers and they exceeded my expectations. The sound is crystal clear with rich bass, and pairing them for stereo mode creates an amazing immersive experience. Bluetooth connects instantly, battery easily lasts a full day, and the water-resistant design makes them perfect for outdoor trips. The modern design with LED lighting adds a fun touch to any gathering. Absolutely worth it and I highly recommend them

Looking for a new Bluetooth speaker with good bass sound. I have owned UE Wonderboom 3 for a long while. Thought I was going to be purchasing a JBL until I heard this Sony speaker on display. It sounded way better than JBL. The Sony sound was clear and there are two bass boosts modes to choose from. I listen to both heavy metal and rap music. Glad I chose the Sony, great sound and awesome battery life. It is on the heavy side and there are not many choices for a travel case since it was just released recently.

Picked this up for a price I had to read multiple times to confirm. Great price (at least at the time of purchase). Loud, clear sound. Deep bass. Lights are a nice touch. The strap helps with portability, as this thing is a mini beast. Really happy with my purchase.

Alright, so first off—this thing is huge. I wasn’t expecting the Sony ULT FIELD 5 to be the size of a loaf of Texas sized bread. Not a bad thing, just caught me off guard having ordered sight unseen. It’s got a little weight to it too, but nothing crazy. Feels solid and tough, like it can take a few bumps without worry. Definitely built for the outdoors. I went with the white one since I plan to use it mostly by the pool. Looks sharp and clean, but if you’re taking it to the lake or beach, I’d probably lean toward the black version. The fabric seems like it’ll clean off okay, but I wouldn’t be shocked if it picked up some stains over time. Getting it set up was easy. Just powered it on, paired through Bluetooth, and I was good to go. But if you want to really mess with the settings, you’ll want the Sony Sound Connect app. There’s an update right away, and then all sorts of stuff opens up—most of which I’ll probably never use (DJ mode? Nah). What I did like was messing with the party light colors. The controls for that are kinda buried in weird spots in the app, but once you find 'em, it’s cool. I’m not big on all the flashy color changing stuff, but I found a mellow setting where you can just pick one color and it pulses with the music. Pretty slick. Now, the sound? It’s absolutely killer. I listen to a lot of stuff that isn’t real bass-heavy, and it still blew me away. I had Gary Louris crooning at full blast, and it was crystal clear. That ULT button mode gives the sound a nice punch to it without things getting muddy. Originally, I figured I’d use it outside or maybe in the garage, but I ended up bringing it inside and plugging it into my gym setup with a 3.5mm Airplay adapter. The AUX-in worked great, though there’s a slight delay when trying to sync it with other speakers over my home network. Would’ve been nice if Sony built in some kind of WiFi or AirPlay support. At this price, it’s definitely nice enough to use indoors, and I just wish the integration was a little better. One thing I really appreciate is being able to charge my iPhone right off the speaker with USB-C. Super handy, especially outside when you don’t wanna burn through your phone battery streaming music. Bottom line? This thing rocks. It sounds amazing, looks sharp, and feels like it can go just about anywhere. The lack of networking is the only real miss for me, but otherwise, I’m seriously impressed. Gonna be using this a ton this summer.

Excellent sound quality and worth the price if you can afford it it can be a bit heavy at times and I'm glad that they added the carrying strap with this model and the Bluetooth range is amazing I can walk across an entire factory warehouse building with my phone and it continues to play no matter where I am in the facility so if you're looking for a strong connection this definitely blew my expectations out of the water

Sony ULT Field 5 Bluetooth Speaker – Quick Review The Sony ULT Field 5 packs serious bass and bold sound, especially in ULT 2 mode, making it great for outdoor parties and casual listening. While it may not offer the most refined audio compared to higher-end speakers, it delivers a fun, bass-heavy experience that suits its purpose well—especially when on sale. With features like a 360° Party Light, Party Connect (link up to 100 speakers), IP67 waterproof rating, and up to 25-hour battery life, it’s built for portability and fun. The sound is punchy, though some may find the EQ limitations on ULT modes and its weight a downside. If you’re after pristine audio fidelity, there are better-sounding speakers out there. But for what the ULT Field 5 is meant to do—loud, rugged, portable fun—it’s a solid choice at the right price.

Sound quality is incredible. Surprisingly powerful for its sized. The sound fills the room effortlessly. Love the design and the lights add an extra special touch. It's small enough to carry with you anywhere you go. To the park or a friend's bbq. Love it.

Solid performer and a great buy when it’s on sale. Avoid paying full price as your experience might be construed a bit. For the 250 range this speaker hits hard and carries an excellent sound up to around 80% where the DSP limits the bass response a bit. Major positive is you don’t experience distortion and it gets really loud outdoors. Just know the speaker has its limits. Solid performer against the job extreme 4 and to my ears max volume sounds better. Ult option 2 boosts highs and lows so you might enjoy ULT option 1 more if you are craving deeper bass. Major downside is that even with a custom eq, you can’t adjust the speaker to sound any better than either of these modes so I find myself just using either Ult option. Battery life is great and I enjoy the lighting and fairly flat sound profile. Great speaker outdoors and will serve you well for indoor parties if you place near a wall to help out the low end. Two units provides an amazing stereo sound and I highly recommend if you wallet allows it.

I recently purchase this speaker in black. I’m an avid Bluetooth speaker nut and I have quite the collection for diffrent uses when traveling on the road as a touring musician. I have all the heavy hitters from JBl, Bose, and soundcore and I recently picked up the Sony ULT 7 on a limited time special deal for a price I couldn’t pass up. I enjoyed the ULT 7 so much so I had to grab the other speakers in the lineup including the Soly ULT 1 as well as the ULT 3. I was missing the ULT as my local beat buy was out of stock until this last week. I saw the recent price drop of over 80 dollars so I had to add this new Sony tech to the collection. Put it this way, I enjoyed the ULT 5 so much that I bought a second one to run in stereo. This new Sony lineup is a huge upgrade if you are coming from the Sony xb 43 or the xg300 like I did! My view of the Sony line is that they have all of the bases covered from large parties down to the occasional hotel room/lounge speaker. Each speaker delivers for its use case and the Sony ULT 5 is no acception. Each speaker has its weird quirks at lower volume, the ULT 7 and the ULt 1 tend to be a bit bass heavy at up to 40%, the ULT 3 and 5 go in the opposite direction and they sound more muddled in the mids and highs at lower volumes and the bass doesn’t really hit you until you pass that 40% mark. The ULT 3 losses a majority of its hard hitting bass at around 65% [much like the ULT 7 and the ULT 1) but the auLT 5 kicks into full overdrive throughout the full range up until 90%. Beware as this speaker can get really loud and it really sounds it’s best at over 50% so I would highly suggest the ULT3 if you listen at more casual volumes. The ULT 5 will Likely too loud when you have the ULT mode 2 engaged for medium to small rooms/apartments. Punchy low end without sounding muddy and the vocals and high end come through fantastic as you start pushes the volume up button. My take on the sound signature is the ULt 5 is clearer defined low end and less fatiguing on the ears in comparison to my former road workhorse, the JBl extreme 3. Side note, the ULT 5 will not rival its larger competition like the ULT 7 or the JBl boombox (still an old favorite of mine), but it’s an absolute beast in a medium to large room and performs quite well outdoors for medium gatherings at the park or on the beach. Looks are typically irrelevant, however I enjoy the non “football” look in comparison to my larger JBL speakers. Lighting looks great on my white model but the darker color on my black version really seems to not illuminate as well. So if lighting is a selling point, pick the white version. The strap feels premium and it’s a welcomed feature as this speaker is a bit too large to grip in one hand when carrying multiple items. Cloth on the speaker seems to repel marks and scuffs well so far (I’ve bumped into a few things and door frames when trying to carry to much) Reason for the 4 stars? Sony’s apps are not nearly as polished and the Fiesta app (for dj and party light controls) refuses to work on my IPhone. Constantly booting up into a black screen even after restarting and uninstalling the app and reinstalling. Feels like you are missing out on some extra features as you are not able to access everything this speaker can do on the Sony connect app. Sony connect app works okay but sometimes won’t connect to your speaker if you don’t close and reopen the app. Custom EQ is also kinda worthless as you can’t get quite the sound clarity and pressure when using any custom eq’s no matter how you tweak the settings (custom EQ disables all ULT modes which significantly improve the speakers output in the full range. All in all, I can highly recommend every speaker in the Sony lineup and even more so when they go on sale. MSRP is a bit high so I would personally wait on a sale of some sorts for any of their current lineup.

Amazing speaker. Ive owned plenty of JBL speakers since the first flip came out. But Sony really nailed this one. I get better battery life and better sound quality compared to the Xtreme 3. The light show is something I never thought would make a speaker look more appealing. Very satisfied.

Love this speaker it’s perfect size, loud, and nice lights. Battery is durable

The Sony Field 5 speaker delivers exceptional audio performance, characterized by remarkable sound clarity and powerful, impactful bass. Its versatile multiple sound settings are a significant asset, allowing users to optimize the audio output for various environments. Beyond its impressive sound, the Field 5 boasts excellent battery life, further enhanced by its ability to charge other devices while simultaneously playing audio. The accompanying mobile application significantly enhances the user experience, providing convenient remote control for power functions, an equalizer for personalized sound adjustments, and seamless connectivity with other compatible devices. For future iterations, I would suggest two key enhancements. Firstly, the ability to connect with speakers from other brands for a multi-speaker setup would greatly expand its versatility. Secondly, the availability of a dedicated protective cover would be a valuable addition, offering enhanced durability and peace of mind for users.
