ULT Field 3 Wireless Portable Bluetooth Speaker, IP67 Waterproof, Dustproof, Rustproof, and Shockproof with Enhanced Bass, 24 Hour Battery and Shoulder Strap (SRSULT30B), Black

The Sony ULT Field 1 is perfect for the price you are paying for, it's a good speaker in terms of Sound, bass and size, it's a good sized speaker, the carrying strap built in the speaker is perfect for carrying, Bluetooth connectivity is good, the battery is good enough for most people, and the stereo pair feature in this speaker makes it sound even better! I did do a comparison with the JBL Flip 7, and the Sony ULT Field 1 is better in sound quality and it's cheaper. So if you want a good speaker for a good price, get the Sony ULT Field 1.

This is an amazing speaker. Although it is very portable, it does verge on being too big to carry around with you everywhere. I'm no audiophile, but this speaker sounds great to me. It carries a proper punch and the highs are nice and crisp. There is a noticeable difference in sound with the ULT mode off or on. You're going to want to keep it on if you want that rumbling bass sound, but there's enough boom with it off. I haven't dropped it and don't plan on doing so, but the rubber molding on each end feels sturdy and able to absorb a decent fall. The waterproof feature is nice in case you ever leave this speaker out in the rain by mistake or want to keep it near a pool. Battery life is great. I have not timed it, but the battery last for serval days with multiple hours of use per day. I'm confident the battery claims from Sony are accurate. The ULT Field 3 is the sweet spot if you want a speaker that can be your primary Bluetooth speaker as well as a portable option. Get it. Your neighbors might hate you, but your ears will love you.

We were on the market for a bluetooth portable speaker for our 18 year old daughter as a birthday present. We normally gravitate to the JBL brand - which ARE, and still remain to be, great speakers. But, being the baby of the family and living with hand-me-down [you name it]s all her life, I knew she'd appreciate a speaker in a style that was totally her own -- not another one of mom and dad's (or big brother's) speakers. Fun and easy as that sounds, this meant stepping out of my comfort zone. (You know how it is: you like what you like!) So I REALLY did my homework by researching many different brands/styles/specs (Bose, Beats, etc.) of speakers in the (about $100-150) price range. The number one thing our daughter was asking for was portability - hesitantly saying nothing bigger than her brother's JBL Charge 4, but I could tell smaller would be better. Bigger speakers may give better sound, but she wanted a "water bottle speaker" as they're called because they fit nicely in cup holders. So I began my search by comparing models to JBL's Flip 6 - the one I was originally going to purchase. I came across this Sony ULT Field 1, which is a new model that Sony released just a few months ago. I was impressed by it's veratility. Built the same way as the Flip 6 (outward facing woofer and tweeter, side bass) it has many of the same features as the Flip 6 like an app with an equalizer so you can fine tune your music and 12 hours of battery life. But the Field 1 came with a few extra features that raised my eyebrow... A ULT bassboost button giving you an extra, little option: go with a deeper bass if you're dancin' the night away - or turn it off if you're, say, talking with friends around a campfire and save on battery life. (By the way, it sounds GREAT even with it off!) It also comes with a phyical pause button and voice feature - where you can answer the phone through the speaker, (like in your car). Although it IS bigger than the Flip 6 it is smaller than the JBL Charge 5 - the newer version of her brother's speaker. As far as sound quality, several reviewers (YouTube) stated that the Field 1's sound quality falls BETWEEN JBL's Flip 6 and Charge 5 models. (I used my headphones to listen while they demonstrated the different speakers' sounds and, yes... uh-huh... I agree.) Again, ALL 3 speakers have very, VERY good sound quality - you really can't go wrong with any of them. We were looking at Sony's ULT Field 1 simply because we wanted to give our daughter something unique to our household - that fit her description of "bottle speaker" but measured up to my (ha!) standards of sound quality. I also want to point out (on a petty note) that we DO LIKE the carrying cord - a feature I thought at first glance might be awkward. It can be removed if desired but lemme tell ya, it's QUITE handy! :D So I added it to my cart, did that lil' 'hold-your-breath' pause thing we all do ...then tapped the 'ORDER' button. It arrived today (very next day) and, wanting to surprise her [a month] early, went ahead and handed her the package. (Sigh...gone are the days of my elegant gift wrapping sessions.) The surprise alone tickled her - but when she opened it, her eyes grew WIDE! She genuinely LOVED it!! (May I be clear here: I couldve given her a cleaned up, secondhand, garage sale speaker and she, in her sweet-nature, would have "LOVED" that. Ha! Ha! It was a sweet treat to do this for her.) 😄🥲 I asked if the size was too big and she said it was very much OK! Now, my picky ears are truly impressed by it's CLEAR sound - even turned ALL the way up, there's no "fuzziness" here! I had chosen the white color and it's very nice. It's not a sporty, bright white - just kind of a classy, muted off-white. One thing I DO like over the JBL brand is that the buttons have little, lights by each one so they'll be more easily seen in the evenings. (Cool!😎) Connectivity was easy - or so I assume. She had it out if the box and connected to her iPhone faster than I could say "Wait; there's an app...". She was already downloading the app and was playing music as I sat at down at the table to look it all over. So I'm feeling pretty confident to say it's easy to set up. As far as fitting in the cup holder, it does fit...kind of. It sits about 2½ inches down - snuggly enough to keep it securely upright while driving, but not all the way seated down inside it. Our car's cupholders (Ford Escape) have these little spring loaded, retractable, grabber things that prevent it from being seated all the way down inside. Bump it with your elbow and it'll go flying. That said, it still may fit in YOUR cupholders. It definitely will fit the (Ford) truck's cupholders. Lol! She loved the speaker so much though, it wasn't a deal breaker! After all that - go figure! (RME) But, hey!...that just tells you how good this speaker is!!) Overall, it is very much a sweet little speaker for its size and price point! (Way to go, Sony!) As they say in other Amazon reviews: "If you're on the fence give it a try - you will be pleasantly surprised." (🤔Hmmm...Let's see... MY birthday is in March...) 😄

Super speaker. Purchased Sony ULT Field 1, JBL Flip 6, Bose SoundLink Flex and SoundLink Revolve +II for comparison (give away Bluetooth speaker at end of annual international trips, so I go through a few of them). Have also had several UE Boom 1-3 (unbeatable speakers, but no longer available), and a few cheaper Bluetooth speakers. My criteria include: battery life, weatherproof, sound quality (realism rather than bass-heavy, although good base is required for projection, especially outside or when on boats or with much noise), size, portability, volume without distortion, affordability (~$100). All are comparable in most aspects. Full volume level is very similar, none distort, bass is a little more distinct in JBL. Soundstage is absent with all, but mid- to high-volume compensates for this, and projection is good with all. Running two UE Booms was a good way around this, but I want to carry only one speaker (traveling, in the garden, fishing, etc) and not deal with proprietary apps required to run two in stereo. The JBL beats all for portability (size, shape, hanger), with the Sony right behind (just a bit larger). SoundLink Flex doesn’t project quite as well, but is still a great speaker (when on sale and cheaper than the other two). The Revolve +II sound quality, projection, soundstage and volume beats them all, but is too large and expensive to carry on trips, so was just used as a comparison to what a Bluetooth speaker could do (nothing even touches the sound quality of the Sonos Move, that I borrowed from a friend - out of curiosity only - doesn’t fit my criteria of portability or affordability). In short - you’ll be happy with any of these three, but I’ll stick with the JBL and Sony until no longer available.

Excellent!! I am an audiophile! Having said that, I pay attention to all things sound quality related. If you are like me, MP3 files etc don’t cut it. This model was made for the demanding listener. Not all Bluetooth codecs are the same My FiiO M11+ portable player has Ldac and a 3.5 Line output. Both of these feature are able to be utilized on the Sony ult field 5. I play dsd and ripped cd files from my FiiO to the Sony. The sound of the Sony is often described as bass heavy. Nonsense. This speaker on the ult2 setting is rich full and natural. The speaker walks the fine line between just enough bass to sound natural,(bigger drivers) and reasonable Portability. The amplifier has decent power output to get to enthusiastic loudness, but still sounds very natural at modest levels as well, and a substantial sized lithium battery to have long all day listening sessions. Like other reviews have pointed out, the colour changing lights are a surprise. They are not too flashy, or over done. They add to the experience. The carry strap is very well made with the ends being metal and not plastic. The sound quality is very well tuned and musical. It is not boomy overblown bass. If you play lesser quality low bitrate files on a lesser Quality Bluetooth codecs, then perhaps you will have a different sound. But careful examination of this models features and build quality and its weight,(7lbs) will tell you the type of audio quality to expect at high bitrate playback over Ldac Bluetooth or direct line input, which is necessary for excellent sound quality. This is a portable Bluetooth speaker for the discerning listener. Well done Sony!

Llegó rapido, buen sonido y es una marca que garantiza calidad, sin duda la recomiendo y mas con un descuento.

Excelente muy bueno producto excelente muy buen producto

Don't get Confused just buy it, you won't regret. Sound quality is top notch, great clarity for a bluetooth speaker. It supports HIRes bluetooth codec like LDAC not many speakers have these although you need to be a android user. For better experience and comparison i suggest to visit store to experience the by yourself. For portability, it is heavy like 3.3kg but solder strap is given and with solder strap the portability is not an issue. Battery life of this speaker is also good and you can use external power source like ac adaptor also with type c and get extra boost on bass and volume. Party light is also very cool. Overall is a great speaker total value for money in this price, (better sound than JBL xtreme 4). Build quality of this very top notch, have ip67 rating. In the functionality, the Sony's party connect is there if you have Sony's other speakers which have this feature. Can connect two same speakers as in stereo although the speaker it self is stereo. In the back io panel there is also a aux in port for audio and the speaker can be a powerbank to charge your phone. All these things which make this speaker great in functionality.

Es más grande de lo que pensé. La conecté a mi tv y se escucha bastante bien. La volvería a pedir.
