Product details

Powerful woofer in a portable design for impressive, room-filling sound. In combination with a high-quality tweeter and two passive radiators, it produces rich, detailed sound with a convincing punch. Adjust the sound to your liking with the 7-band equaliser in the Sony | Sound Connect app.

When you press the ULT button, the ULT Field 3 reveals its true strengths. Boosted bass and increased sound pressure provide a captivating, energised ULT Power Sound experience.

Weighing just 1.1 kg, measuring approx. 25 cm in length and easy to carry in one hand, you can take the music with you wherever you go. The detachable shoulder strap makes it easy to carry, and for true versatility, the speaker can be positioned both horizontally and vertically to fit into any room.

With 24 hours of battery life, you can enjoy powerful sound from morning to night. The quick-charge function provides an additional 2 hours of playback time in just 10 minutes.

You don't have to worry about the weather or the environment - the ULT Field 3 is waterproof and dustproof to IP67. It is also rust and shock resistant.

Sony's sound field optimisation enables clear sound even in noisy environments.

You can also make crystal-clear, hands-free phone calls with the ULT Field 3. The echo minimisation technology allows two people to talk at the same time without interrupting each other.

For optimal connectivity and control, the speaker can be controlled via the buttons on the top of the device or via the Sony | Sound Connect app on your smartphone.

For an even better sound experience, Party Connect allows you to connect up to 100 compatible Sony speakers via Bluetooth. If you have another ULT Field 3, you can use Stereo Pair to create a powerful stereo system.

  • PositiveSimple, high-quality design
  • PositiveEyelets for carrying strap well hidden
  • NegativeSound could be more balanced

Even more than the Ult Field 1 and 7, the Ult Field 3 gives the impression that Sony is not just trying to appeal to the younger target group with the fresh Ult label, but is attempting an all-round approach. The design is timeless and surprisingly restrained, but still offers the flexibility and robustness that you would expect from a Bluetooth speaker of this price and size...

  • PositiveSimple operation
  • PositivePowerbank function
  • Positivecomprehensive app
  • NegativeSound somewhat unbalanced
  • Negativequite heavy and large

The Sony ULT Field 3 offers a good overall package. The battery is long-lasting and the power bank function provides power for smartphones and other devices. The speaker looks great, but it also weighs quite a lot. In addition, the sound is never quite perfect: without the optional ULT boost, it lacks substance; with the bass boost, it is a little too powerful and boomy.
