Portable Stereo Pair for Anywhere Listening

Two Sony ULT FIELD 1 speakers form a wireless stereo pair designed for indoor and outdoor use. The compact units are shockproof and carry an IP67 rating against water, dust and rust. A built-in Sound Diffusion Processor widens the audio stage so music fills the space evenly. Each speaker delivers up to 12 hours of playback on a single charge.

Check Bluetooth Source and Placement

Verify that your phone, tablet or computer supports Bluetooth audio streaming to connect the pair wirelessly. Ensure the intended location can accommodate two separate units for true stereo separation. Confirm that a USB power source is available for recharging the internal batteries when needed. The speakers have no wired inputs, so a Bluetooth source is essential.

Suits Mobile Music Fans, Not Fixed Installations

This stereo pair suits listeners who want portable, durable sound at the park, beach or around the house. Buyers needing a permanent home-cinema front stage or multi-room wired integration should look at alternative systems. The battery-powered design is not intended for always-on desktop monitoring. Users who require voice-assistant microphones or app-based EQ controls will not find those features here.

Questions about this item

Does the stereo pair include both speakers and a charging cable, or do I need to buy a cable separately?

The stereo pair supplies two ULT FIELD 1 speakers; a USB-C charging cable is included in the box so no separate purchase is needed.

Should I choose the single speaker or the stereo pair for wider sound coverage?

The stereo pair links two units wirelessly for left and right channels, giving broader sound diffusion than a single speaker.

What does the 12 hour battery life mean for a typical listening session?

You can play music continuously for up to 12 hours on a full charge before the speakers need recharging.
