    • The Field 7 is the best large BT speaker to date.
Style: ULT Field 7
I’m back with another speaker review, help, and Sony has really knocked it out of the park with this one. I’ve mainly used my Boombox 3 for comparison against the Sony Field 7, and while Theodore Roosevelt said, “Comparison is the thief of joy,” he wasn’t wrong—it’s tough to resist comparing speakers side by side. The only area where this Sony doesn’t excel is in the sub-45Hz range, though it still gives it a good try. While the Boombox 3 rumbles a bit more in that low-end, this Sony more than makes up for it in other areas. The ULT2 in this Sony decimates every portable system I’ve heard. The sound separation is fantastic, allowing every layer of your music to shine. Battery life is impressive, too. I left it unplugged for about a month, using it nightly for about an hour, and only after 30 days did the charge light come on. That’s serious endurance. The multipoint connection works seamlessly between my tablet and iPhone, making it one of the few systems that hasn’t caused me any frustration. The lighting is another standout feature—far brighter than I expected. Unlike the dim ring lights on the SRS 300, these lights provide enough glow to add some nice ambiance, though not quite enough to light up a room or throw a strobe party. And durability? It’s built like a tank. You could even turn it on its side and use it as a stool. Overall, this speaker delivers in almost every category, making it one of the best I’ve encountered. ... show more

    • Great speaker, Amazon, not so much.
Style: ULT Field 7
Speaker gets loud and has a lot of bass. A great feature set. I wish they would have given it a proper tweeter dedicated for the high frequencies. Overall don’t regret buying it. Two in paired stereo mode is awesome. As far as Amazon though? I bought this speaker after I decided the UE Hyperboom that was on sale seemed to have some longevity quality control issues. For this Sony speaker however, Amazon lowered the price $100 two days after I purchased and because they suck, wouldn’t just do a price match even after talking to someone on the phone. Nope, they want you to buy a new one and return the “old” one. Well I had already opened the speaker. I was so impressed and knowing that I wanted to get a second eventually, (something I had also wanted to do with my old portable speaker) I ordered two more. Then I immediately returned one of the new unopened ones back to Amazon at the higher price because they don’t care about wasting time or fuel. The funny part is after being told they wouldn’t price adjust, when I initiated the return process, they auto offered $89 off to keep it. (Already ordered the two new ones) Now that is basically 20% off their regular price. (Also of note, when they discounted the price $100, they used a higher price as the point they were discounting from in their sale to be able to say it was 30% off when really it was about 22% off the price I paid days prior. More shady business practices.) While a part of me would have been willing to maybe forgo the $18 difference ($10+ tax) between the offer and what I paid just to save some environmental impact, out of principal, I made the return for my extra $18.

    • Sony is always a solid choice...
Style: ULT Field 7
Excellent sound quality - even when you use the bass boost it does not overwhelm the mids and highs. It is easy to pair with two phones/DAPs/whatever at once. I love the minimalistic look of the speaker as well. It is not very heavy and is thus easy to move around. I am planning to buy another one and use them in tandem which I can imagine will be incredible from a sound experience standpoint. I dont think they get as loud as JBL speakers this size but I will take that L for the superior sound quality. I have used this outdoors (not in any extreme weather conditions but normal sunny to cloudy cold days) and havent had any issues thus far. ... show more

    • Great, excellent, wonderful.... Almost.
Style: ULT Field 7
Clear highs, excellent battery life, incredibly simple to use. it's a very powerful speaker with a lot of useful bass and clear, identifiable high end that shows off the music like you've never heard it before until...... You turn up the volume to "quite high". That's when I noticed a buzz and distortion with the bass and treble. But you don't have to go to "quite high" to enjoy the Sony ULT Field 7. It provides quite the listening experience. Especially if it's your first big bluetooth speaker. I just think that for the price, it should remain steady when pushed to its volume limits. ... show more

Style: ULT Field 7
My speaker came fast and brand new sounding great. Great balanced highs n lows, bass, tremble and all. I was surprised it came that fast from newark new jersey to newark california. I was thinking in a week. Good seller n customer service.

    • This thing is a MONSTER!
Style: ULT Field 7
Dude its bigger than you think! Imagine a standard portable speaker, but for giants. THATS what this is. The power is absolutely BONKERS! My neighbors even yelled at me. And it was barely any volume! At max volume, its barely distorts! The software is a bit scrambled all over, the Ui on the app is an outdated feeling. And a couple weeks later, I FOUND OUT ITS SUPPORTED FOR LDAC! which is crazy for the size of this thing! Portability isn't very ergonomic because of how heavy it is. There probably are accessories for it so it helps with it, but oh well. Its good for the use. Charging speed is a little longer than most things I've charged. But who cares! This is a proper product from sony! This is why I trust sony in the deep of my heart. The fact its 45 watts max power is insane!! I like the light shows it has. I love how it literally syncs to the song itself! The light show colors are very vibrant. This is probably the most positive review I've laid my hands on. Absolute beast of a speaker! You can even use it as a guitar amplifier speaker if you wanted! And it still sounds good! ... show more

    • I bought & compared them all, THIS IS IT!
Style: ULT Field 7
Sound geek: I bought & compared the larger Bose JBL Sony and Soundcore, this one was the best sounding BY FAR! I do like the Soundcore (yes more than bose or jbl) one for carrying around to the beach n other dirty outdoor stuff as its cheapest among them and easiest to clean but for EVERYTHING else, the Sony Field speakers are my absolute go-to pick as the batteries last forever and the sound is definitely the best. Only minor gripes are the annoying flashing of the ULT button and the BT volume notches are too jumpy; solution is to use the buttons on the unit its self. But seriously, these are great, Sony did it again. I’ve honestly been impressed by most things they make. Typically solid performance and pretty much bulletproof. Like the honda or toyota of electronics. ... show more

    • Amazing sound quality
Style: ULT Field 7
I watched several side by side sound tests on Youtube with several speakers I was interested in purchasing. I first purchased the Soundcore Motion Boom Plus. It sounded good for it's size and cost but I was looking for something more. So I then decided to upgrade and try the new Boom 2 Plus by the same company which was a little more expensive with more bass and more watts of power. It was good but only to a certain point. I liked the bass but the highs sounded muffled. I wanted to go into the app to adjust the EQ settings so I could bring out those highs but was never able to do it due to the problems with their app. The speaker was not listed on their product page for me to download it so I was never able to adjust the EQ settings and was bummed out by it. I watched some more side by side comparisons on Youtube of other speakers and was impressed with the Sony ULT Field 7. After watching and hearing a few side by side comparisons of it against other speakers, to include the Boom 2 Plus, I was ready to purchase it. After I received it I put it thru it's pace and was quite impressed with it's sound quality after hearing it live. It brought out the full spectrum of the music and sounded more dynamic and powerful through out it's range. There was a spacious atmosphere of sound quality coming out that didn't sound like it was coming from a speaker box, but instead from a more expensive high end audio source. I was quite pleased with it and would recommend it to anyone else. ... show more
