Sony ULT FIELD 3 Speaker – Forest Gray

Built for the adventurous listener, the Sony ULT FIELD 3 Portable Bluetooth Speaker in Forest Gray (SRS-ULT30/H) is engineered to deliver punchy, immersive audio anywhere life takes you. A 2-way active driver system — pairing a dedicated woofer and tweeter — works in concert with a side-mounted passive radiator to produce well-balanced sound with deep, satisfying bass, all without adding bulk.

Hit Hard, Play Long

One press of the signature ULT button unleashes an instant bass boost, cranking up sound pressure for that front-row concert sensation. When the music matters more than the clock, a 24-hour battery keeps the party alive from afternoon into the early hours — and a 10-minute Quick Charge tops up enough power for 2 full hours of playback. The USB-C port doubles as a power bank output, so your smartphone stays charged too.

Tough Enough for Any Environment

Rated IP67 waterproof, dustproof, and shockproof, this speaker shrugs off beach sand, rain, splashes, and everyday knocks without missing a beat. Connect two devices at once via Multipoint Bluetooth, link up to 100 compatible Sony speakers with Party Connect, or pair two ULT FIELD 3 units for true stereo sound. A built-in mic with echo cancellation handles hands-free calls, while the Sony | Sound Connect app unlocks a 7-band EQ and Sound Field Optimizer for tailored listening. The detachable shoulder strap makes every journey effortless.
