Sony ULT FIELD 3 Wireless Speaker Forest Gray

Portable wireless speaker for outdoor listening

The Sony ULT FIELD 3 is a compact Bluetooth speaker built for music playback in open spaces. An IP67 rating means it survives full immersion in water and total dust ingress, while the stowable shoulder strap makes it simple to carry on hikes or to the beach. A 2-way active design with a dedicated woofer and tweeter handles the frequency range, and the ULT button adds a bass boost when you want more low-end weight. Battery life reaches 24 hours on a single charge.

Suits travellers and party hosts.

This speaker fits users who need rugged, grab-and-go sound for camping, poolside gatherings or tailgating, and the Party Connect feature lets you link several compatible units for wider coverage. Quick charging delivers 120 minutes of play from just 10 minutes on the charger, so short stops keep the music running. Buyers who require flat frequency response for studio reference work or who need a wired analogue input for legacy gear should look at a different product class.

IP67-rated 24-hour battery

The combination of IP67 protection and a 24-hour runtime means the speaker can stay outdoors through rain, sand or dust without daily recharging. When the battery does run low, a 10-minute top-up restores up to 120 minutes of playback, reducing downtime on multi-day trips. This durability-to-endurance ratio is the specification that decides whether the unit matches an all-day, all-weather use case.
