Sony ULT Field 1 - Black arrives as a rugged mono portable speaker designed for on-the-go listening with an IP67 rating for water and dust protection.

This tube-shaped speaker houses a single speaker configuration with a dedicated woofer and a tweeter, delivering a clear, balanced soundstage. The woofer supplies 20 W RMS while the tweeter contributes 10 W RMS for a total rated power of 30 W, making the Sony ULT Field 1 well suited for personal outdoor listening and small gatherings.

Connectivity is modern and wireless: Bluetooth 5.3 supports profiles such as A2DP, AVRCP, HFP, HSP and SPP with an effective range of up to 30 m. There is no Wi‑Fi, but a USB Type-C port provides USB connectivity and a USB 2.0 port for charging and playback compatibility.

The built-in 2900 mAh Li‑Ion battery offers up to 12 hours of playback on a single charge and recharges in about 5 hours via the included USB Type-C cable. Power consumption is efficient (typical 7.5 W, standby 0.3 W), and the device supports USB Type-C charging between 2.5 W and 15 W.

Designed for durability, the black chassis is rust- and shock-resistant and carries an IP67 protection rating, making it ideal for beach days, hikes, and poolside use. The omnidirectional built-in microphone and hands-free mode simplify calls and voice interactions while on the move.

At 206 x 76 x 77 mm and 650 g, the compact tube form factor is easy to carry and fits into backpacks without taking much space. The package includes a USB Type-C cable, a quick start guide, and a warranty card; no AC adapter is supplied.

Practical use cases include taking the Sony ULT Field 1 on camping trips, using it as a portable companion for bike rides or picnics, and adding a robust voice-enabled speaker to home desks or balconies. Its AAC and SBC codec support ensures broad compatibility with most phones and tablets.
