Sony ULT FIELD 5 - Powerful Bluetooth Portable Speaker, 25hr Battery, 2 x ULT POWER SOUND modes, IP67, Waterproof, Dustproof, 360 Lights, Detachable Shoulder Strap, Compact

Introducing the ULT FIELD 5.

Drawing on decades of Sony audio expertise, the ULT FIELD 5 delivers impactful, room-filling sound from a portable design. A large, powerful woofer combines with two high-quality wide-range tweeters to produce impressive audio with a satisfying punch, while dual passive radiators on either side enhance bass, adding depth to every beat.

Tailor your sound using the 10-band equaliser and selection of presets in the Sony | Sound Connect app.

The ULT FIELD 5 has two ULT sound modes, available at the push of the ULT button: Deep Bass adds huge resonating depth to the music by boosting the lower frequencies, and Attack Bass increases the sound pressure, adding even more energy, volume, and power to the music. 

Striking the perfect balance between power and convenience, the speaker is large enough to deliver powerful, impactful audio yet compact enough to remain highly portable. A removable shoulder strap is included.

For versatility, the ULT FIELD 5 works both horizontally and vertically to fit any space.

With 25-hour battery life, keep the music playing all day and night. And when you’re running low, a quick 10-minute charge will prove 100 minutes of playback.

360° LED lighting automatically syncs to the beat and sets the scene. Use the Sony | Sound Connect app to change the colours, light patterns, or to switch them on and off.

The ULT FIELD 5 is waterproof, dustproof, and rustproof.

Sony’s new Sound Field Optimisation feature ensures clear sound, even in noisy environments.

For ultimate connectivity and control, the speaker can be controlled via buttons on top of the unit, or in-app on your smartphone.

For an even bigger sound experience, Party Connect lets you link up to 100 compatible Sony speakers via Bluetooth, and if you have another ULT FIELD 5, Stereo Pair will create one powerful stereo system.

ULT POWER SOUND

Hit the button. Feel the bass

The ULT FIELD 5 has two ULT sound modes, available at the push of a button, to unlock its true power: Deep Bass and Attack Bass.

Deep Bass adds huge resonating depth to the music by boosting the lower frequencies. Attack Bass increases the sound pressure, adding even more energy, volume, and power to the music.

You can switch between the ULT modes by pushing the ULT button on the top of the unit, or directly through the Sony | Sound Connect app.

Portability

Take the music with you

Large enough to deliver powerful, impactful audio yet compact enough to remain highly portable, the ULT FIELD 5 strikes the perfect balance between power and convenience.

Weighing 3.3kg and measuring approximately 32cm in length, this wireless speaker is ideal for use around the home, but thanks to its removable shoulder strap, it’s also easy to take with you.

Designed for versatility, the ULT FIELD 5 works both horizontally and vertically, providing the best sound experience even when space is tight.

Long Battery Life

Powerful sound, all day and night

The ULT FIELD 5's incredible battery life ensures the music never stops. With up to 25 hours of playback*, you can enjoy powerful sound from morning to night—whether you're out and about or unwinding at home.

This speaker goes beyond just playing music; it doubles as a powerbank, letting you charge devices via its USB port. So, if your smartphone battery runs low, simply plug it into the speaker and keep the music going.

Plus, if the speaker runs out of battery, the quick charge feature provides 100 minutes of playback from just 10-minutes charge, so you can spend more time enjoying the music and less time charging.

Party Lights

LED lighting to set the scene

This party speaker sets the mood with its 360° multi-coloured lighting. Surrounding the passive radiators on either side of the speaker, the LED lights automatically sync with the music to produce a hypnotic light display to complement any gathering.

If you want to take control of the lights yourself, you can use the Sony | Sound Connect app to manually change the colours, light patterns, or to switch them on and off.

Clear Sound, Even in Noisy Environments

Clear sound, even in noisy environments

With Sony’s new Sound Field Optimisation feature, this Bluetooth speaker automatically adjusts its audio to provide the best experience, however busy the party might be.

In a room full of people making a lot of noise, or out and about in a noisy environment, the clarity of a normal speaker can be lost. But using our Sound Field Optimisation technology, the ULT FIELD 5 detects the noise and adjusts its audio to remain clear and detailed, always providing its best sound quality in every scenario.

Connectivity & Control

Ultimate connectivity and control

The ULT FIELD 5 is easy to control using the intuitive buttons on top of the unit or the Sony | Sound Connect app. The app provides detailed controls, allowing you to adjust the lighting, enable the ULT POWER SOUND setting, fine-tune the equaliser, and more - all from your smartphone.

For an even bigger sound experience, the Party Connect feature lets you link up to 100 compatible Sony speakers via Bluetooth. Simply press and hold the Party Connect button on top of the speaker to start pairing. If you have another ULT FIELD 5, use the Stereo Pair button to create a powerful stereo system, with one speaker as the left channel and the other as the right.
