ULT Field 7 Wireless Bluetooth Party Speaker, IP67 Waterproof, Powerful Bass, 30h Battery, Karaoke, Comfortable Handle, and Colorful Lights (SRSULT70), Black

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.

I love my Sony ULT Field 7 Wireless Bluetooth. On its ULT2 setting, it pumps out the sound!! You want bass? This speaker system has it with more power to spare. When I first got it and tried it, my grandkids could hear it *clearly* over 150 yards away. As loud as I had it turned up (about 2/3 volume) there was no distortion. It’s unbelievable. The only downside I can see with this system is its size (a little over 20” long) and its weight (14 lbs.). It has good hand support on the ends for easy carry.

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.

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.

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.

This speaker is amazing and holds up to the Sony name. I’ve been buying Sony speakers for over a decade and never disappointed. Bass is powerful and audio is crisp and clear. Handles on both sides is nice due to how large the speaker is. Lighting is great as always but not as good as the Sony SRS-XB43’s lighting. Still the lighting it has does the trick. Battery light seems to be perfect. Only real complaint I got is that the audio sounds the tiniest bit distorted at volume levels above 60%. Either then that , I love it.

👍

Muy bien producto y excelente calidad de audio.

It's a decent speaker but over hyped.... the reason i bought this speaker because of it says that it has a low frequency of 20Hz which i found is not true.... sounds great up to 40% then if you increase volume the sound shift mostly on mid and higher frequency and it's loud but no bass at all even with EQ settings you can enhance bass but still not effective on higher volume... i definitely liked this sound better than jbl boombox .... i am reviewing it again after listening of my six months experience that it's a wonderful speaker and i realized the most fun part is begin with when you put your speaker on ultfied1 mode then you do eq settings with your phone eq not with sony eq app because to use sony app eq you need to change mode in to custom which is not good but trust me once you have set the phone eq on ultfield1 mode this is gonna be whole different level of experience... try it and that's the only reason i am giving it from 3star to 5 star after using my phone eq settings

I heard this model a few months ago at a SONY showroom in MALAYSIA. The first thing I noticed was the extraordinary sound that emanated from it. Crystal clear wide spectrum vocals with superb clarity & bass. I managed to pick this up at Amazon prime day sale for a great price much lower than what I saw in Malaysia & what was initially advertised in AMAZON. Initial reaction is I'm very happy & look forward to an extended use. The speaker is built like a tank meant to withstand nature. Extremely easy to use after some initial charging. The only speaker in competition to this would be the Marshall Tufton which is slightly more expensive than the SONY.
