    • ULT 7 vs Boombox 3 vs PartyBox 120
Style: ULT Field 7
We have the ULT Field 7, the JBL Boombox 3, and the JBL PartyBox 120. all of them are good. the boombox has more bass, the partybox has a better light show if you're into that, but I have to say the ULT 7 sounds better at loud volume than the others. the sound is cleaner compared to the other speakers. i also like the the ULT 7 can be used vertically or horizontally. so for me, the ULT 7 is the best of the three speakers. ... show more

    • Looks good and works very well
Style: ULT Field 7
This was a gift to my husband. He loves to listen to music while relaxing outside on the deck that he built in our back yard. The Bluetooth connection from an I-Phone works well. The sound quality is very good and the volume this speaker can crank out is incredible! That being said, we do not blast our neighbors with the volume, just saying, it can produce the volume when desired or needed. It is portable. We charge it and move it to area we'd like it to be. It is easy to grab the speaker by the hand holds on either side and carry it. An audio message alerts us when charging is needed. ... show more

Style: ULT Field 7
As i mentioned in my title this sony speaker has great size and amazing sound. Super easy to pair with any phone. Just as easy as pairing your phone and car radio. Sony crushed it in making a straight forward and user friendly portable speaker that doesnt require propiatary apps, email and or account.. pair and enjoy with whatever music app you use. Use their app IF you want to . THANK YOU SONY FOR CARING ABOUT YOUR CUSTOMERS EXPERIENCE. ... show more

    • Perhaps a little toooo deep
Style: ULT Field 7
I've previously used 4 sony Bluetooth speakers since a first try with a little SRS-XB32. I saw this become available at a good price after reading some good reviews and had the spare money to replace a big and nice sounding SRS-XG500 that I moved to another room. This is louder and defaults with much heavier bass than what it replaced. Sometimes I'll just be grooving with great music at a loud but not deafening level and the bass content is just too strong, almost shaking the room. Fine if it was a party perhaps but I think I had to tune it a little and take out some bass. However, it does sound great. The biggest criticisms are that Bluetooth is nice and tidy but it drops out a little for a beat occasionally. That's annoying and a wired speaker wouldn't do it. It doesn't sound like a mono source but there is little stereo width due to it all being in the one box, getting good stereo definition would require buying two and grouping them as a stereo pair, or you could keep your head a few inches from one (might as well buy headphones at the same price/quality). Plus, the Sony "Music Center" app for making configuration changes can be a pretty flaky, crashes all the time on one of my recent Samsung tablet models but not on the other. While I can create speaker groups it will only create a "party" group from two same speaker models. I have a pair of SRS-XG300 speakers and grouped as a "stereo" pair they fill a room with great stereo sound but I can't group one ULT Field 7 even with my SRS-XG500 as a "stereo" pair even though they have similar volume and sound. The built in lights are a nice party trick but not much use for anything else, they'll waste enough battery power that I don't normally bother. Non-flashing, calm daylight color can make a nice dark room background that's dimmer than a lamp and better power saving than room lights while reading a book from tablet but aren't bright enough to permit reading a paper book in a dark room. ... show more

    • 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

    • 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
