Review: The Field 7 is the best large BT speaker to date. - 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.
Review: I bought & compared them all, THIS IS IT! - 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.

### ⭐⭐⭐⭐⭐ Sony is always a solid choice...
*by D***D on December 1, 2025*

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.
