Product details
The Sony SRS-ULT30 (Forest Grey)—also called the ULT FIELD 3 in some regions—is a mid-size portable Bluetooth speaker in Sony’s ULT Power Sound series, designed for strong bass, outdoor durability, and longer battery life than smaller portable speakers.
It sits between the compact ULT FIELD 1 and larger party-style ULT speakers, giving you a more powerful, fuller sound with better stereo separation and louder output.
