## Summary description

Sony ULT FIELD 1 is a mono portable Bluetooth speaker designed for outdoor and travel use. It delivers ULT POWER SOUND with total 30 W RMS output (20 W woofer + 10 W tweeter) and a 1.6 cm tweeter. Rated IP67 for waterproof and dustproof protection and shock resistance, it offers up to 12 hours battery life, omnidirectional microphone for clear calls, and wireless connectivity with Bluetooth (SPP, A2DP, HFP, HSP, AVRCP) and a 30 m range. Supports AAC and SBC audio formats.

## Long description

The ULT FIELD 1 is the smallest, most portable speaker in the ULT POWER SOUND range. Despite its compact size, it delivers powerful sound from a combination of a dedicated woofer, a high-quality tweeter and two passive radiators that enhance bass response. The speaker is rated IP67 for water and dust protection, offers shock resistance, and includes an adjustable strap for easy carrying; it can be used horizontally or vertically to suit placement and listening preferences.
Advantages
Compact and lightweight design makes the ULT FIELD 1 easy to carry and fit into a bag while offering a high-output audio performance. The dedicated ULT button boosts bass and increases sound pressure for deeper low frequencies and greater perceived volume. IP67 protection and shock resistance ensure reliable use outdoors and in demanding environments. Fast Pair support and Bluetooth compatibility make connecting Android and iOS devices quick, and the speaker can be paired with a second ULT FIELD 1 for stereo playback. Built-in microphone and echo-cancelling technology enable clear hands-free calls.

How to use

Use the built-in microphone for hands-free calls; the speaker will apply echo cancellation automatically.
Recommendations
For best results, keep the speaker firmware updated and avoid exposing charging ports to prolonged water immersion. If using two ULT FIELD 1 units for stereo playback, place them at a modest distance to achieve balanced left and right channels and fuller sound stage.
