    • Excellent Speaker!!!
Style: ULT Field 1 Color: Black
Review Image by Kit
I looked at a lot of Bluetooth speakers at a local big box store to "test drive" them before purchasing. This model was neither the cheapest nor the most expensive, but it certainly checked all the boxes for me. I use it to "open up" my Martin guitars - the vibration of music simulates playing the guitar, which advances the maturity of the wood. The tone is deep and vibrant, battery seems pretty good, it pairs seamlessly with one of my old phones, it's portability makes it a great size, and it is ridiculously easy to use. They make devices that do this that cost upwards of around $300; this speaker is just as effective, more versatile, and way less expensive! ... show more

    • EXCELLENT Speaker 🔊 👏
Style: ULT Field 1 Color: Off White
Review Image by Debbie
Review Image by Debbie
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...) 😄 ... show more

    • Move aside Bose
Style: ULT Field 1 Color: Orange
I had a Bose SoundLink Micro Bluetooth Speaker in my shower to enjoy music while showering. It was good, nice size and average sound. I gave this Sony ULT Fiel 1 a try and man does this thing puts Bose on the bench. Amazing sound, both on bass and treble, its volumen strength is scary, I cannot use this at half a volume on Spotify because is way to much loud. Nice design too, its battery life is great, worth its price every penny. Fully compatible with my iPhone 16 Pro. ... show more

    • Awesome When You Buy And Pair TWO Ult Field 1's
Style: ULT Field 1 Color: Black
Review Image by Jim
Awesome. Love them! Would purchase the TWO combined again. Great stereo sound with TWO Bluetooth'ed together. Battery life seems very good even with the enhanced sound button on. They connect effortlessly too. And are durable. Mine have fallen to a carpeted floor 3 TIMES because I placed them in precarious spots and their inherent bass caused them to move just a tiny bit enough to fall. Place them on a table top, etc. and no problems. This was my definite user error, instead of any kind of fault. I was looking for sound equal to, or better, than a 1982 Walkman I bought but never forgot. I definitely wasn't disappointed! These are by far, better sounding than 3 other name branded Bluetooth speakers I have purchased. And those, weren't cheap ones either! They possess a balanced sound profile with enough bass too. Clean sound across the entire spectrum! "Thrilling" really. Just don't expect them to sound like there's a dedicated subwoofer attached. But again, I find the bass response very pleasing. Super easy to grab as a pair and carry around too. Genuine "Grab and Go" anywhere! They'll accept either a "Normal / Standard" speed charger or a standard "Fast charger" too. They adapt. Just not something like "Super Fast" chargers. You need to not provide too much "voltage". With varying "amps", they only draw exactly what they need. I would rate these very highly. And would DEFINITELY purchase these TWO again. They will easily fill a large living room, and a good portion of an entire home. Volume is very good and clean even turned all the way up. No complaints here. ----------------------------- * ADDITIONAL INFO I PROVIDED IN "AN ANSWER" TO A QUESTION, POSED ELSEWHERE. BUT, WELL WORTH READING I BELIEVE: I have TWO Ult Field 1's and run them in TRUE STEREO. They automatically connect, even just turning 1 of the 2 on, or BOTH at the same time, from within the appropriate app! If you notice, the Ult Field 1's are THE ONLY Ult Field in the full lineup of speakers which ACTUALLY DO STEREO. The other models ALL connect in "Party Mode" MONO. Now, here's where I think your issues arose. The Ult Field 1's MUST, FIRST-EVER be "stereo paired" in the Sony *Music Center* app, NOT the newer "Sound Connect" app. However, once Bluetooth stereo paired in the Sony "Music Center" app THE FIRST TIME, they'll THEN work fine in Sony's "Sound Connect" too. I found, I simply prefer using the "Sony Music Center" app BETTER, regardless! It seems to provide additional features for the Ult Field 1 over what's available in "Sound Connect". And AGAIN all this, really only applies to the STEREO SEPARATION which ONLY the "Ult Field 1 model" can provide. "Party mode" may be LOUDER MONO, but never actually SEPARATES into 2 different channels for TRUE STEREO. I only know all this, partly because I read the instructions carefully, but also because I loved the Ult Field 1's STEREO PAIRED together so much, that I came back and was seriously looking into the larger versions offered. That was, until I found NONE of the larger speakers provide true stereo SEPARATION when paired and placed several feet apart. This is really because the larger models already separate into STEREO WITHIN *ONLY* THEIR OWN CASE, and NEVER actually do provide TRUE STEREO SEPARATION because it's already locked-in to their, each separate case. I'm keeping my Ult Field 1's because they're the only true way within the entire lineup, of achieving TRUE SEPARATION (of up to several / many distinct, feet apart)! It's one thing I believe "most buyers" aren't actually noticing about the entire lineup. I'm SURE the larger units provide better INDIVIDUAL sound, however when "paired" together they never truly form a separate-able stereo pair. They instead just make additional "volume" and "space-filling" sound in their "Party Mode" of up to many, multiple pairings. I wonder if you initially PAIRED in "Sound Connect" and haven't actually achieved TRUE STEREO SEPARATION yet! If not, DELETE all instances of the speakers existing within whatever apps, then re-Bluetooth pair within Sony *MUSIC CENTER* FIRST. Then, set your speakers several feet apart on separate sides of your head, and truly ENJOY! I'm keeping my little Ult Field 1 pair. Because they provide something special to make up for their otherwise tiny size: TRUE STEREO SEPARATION! (I sincerely hope I didn't mix up the TWO app names within this composition. If you wish to review your "original" instructions, but otherwise threw them away, they can be re-downloaded from Sony's website, of course.) ... show more
