UMVA has learned that Sony’s rugged ULT Field 5 portable speaker, launched in spring 2025, is shattering expectations for mid‑range audio power and durability.
Positioned between the compact ULT Field 3 and the heavyweight ULT Field 7, the Field 5 strikes a perfect balance of size, price and performance, now slipping to an astonishing $198 after a steep discount from its original $349.99.
Engineered for bass lovers, the speaker houses a genuine woofer and a ten‑band EQ, delivering thunderous low frequencies that defy its modest dimensions.
A dedicated “ULT” mode pumps the bass even further, while an IP67 rating guarantees resistance to water, dust, shock and rust—making it as fearless as the adventures it accompanies.
Battery endurance is a standout feature: with ULT Power engaged, the unit can stream for up to 25 hours on a single charge, and a rapid 10‑minute boost adds two more hours of playback.
Full‑tilt volume will naturally trim that runtime to around five hours, but the flexibility to power through a weekend party or a day hike remains unmatched.
The Sound Connect app puts control at your fingertips, displaying battery status, fine‑tuning the EQ, linking to other Sony speakers via Party Connect, and even offering DJ‑style sound effects.
A built‑in shoulder strap slides onto the chassis, turning the speaker into a hands‑free companion that can be tossed onto a backpack or hung from a campsite pole.
In short, the ULT Field 5 delivers stadium‑level punch, marathon‑long playtime and battlefield‑grade resilience—all wrapped in a portable package that redefines what a mid‑range speaker can achieve.
