Sony ULT FIELD 1 Speaker – Black

Meet your next go-to speaker for every adventure. The Sony ULT FIELD 1 Wireless Portable Speaker delivers room-filling sound in a compact, rugged body — engineered to keep up with your lifestyle no matter where it takes you.

At the heart of its audio performance are side passive radiators paired with a 3.3 x 1.7" woofer and 0.6" tweeter, producing rich, detailed sound right out of the box. Want more thump? Hit the dedicated ULT button for an instant bass boost that transforms the listening experience. Fine-tune everything further through the Sony Music Center app, where you can adjust audio settings, browse playlists, and manage speaker preferences from your phone.

Built for the Real World

Rain, sand, drops — none of it slows the ULT FIELD 1 down. Its construction is waterproof, dustproof, shock-resistant, and rustproof, and it's partially built from recycled plastic. A detachable multi-way carry strap makes transport effortless, while the flexible form factor lets you orient it horizontally or stand it upright. Battery life stretches up to 12 hours, so your playlist outlasts the day.

Stay Connected, Stay Hands-Free

Stream music wirelessly via Bluetooth, take hands-free calls through the built-in mic with echo cancellation, and pair two ULT FIELD 1 speakers together for true stereo sound. Android users can connect instantly using Bluetooth Fast Pair with a single tap.
