Review: Sony is always a solid choice... - 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.
Review: One of the best Bluetooth speakers on the market. - 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.

### ⭐⭐⭐⭐⭐ One of the best Bluetooth speakers on the market.
*by E***E on January 12, 2026*

### ⭐⭐⭐⭐⭐ I bought & compared them all, THIS IS IT!
*by S***U on January 23, 2026*

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.
