Introducing the ULT FIELD 1 - the smallest, most portable speaker in the ULT POWER SOUND range.

It may be small, but the ULT FIELD 1 produces huge, impactful sound using a combination of a powerful woofer, a high-quality tweeter, and two passive radiators to enhance the bass.

But to experience the true power of the ULT FIELD 1, simply press the ULT button and you'll hear the ULT POWER SOUND difference. The bass is boosted, adding more depth and resonance to the lower frequencies, while the sound pressure is increased to inject more energy and volume into the music than might seem possible from a speaker so small. It’s a stunning audio performance from a such as compact device.

With an IP67 rating, the ULT FIELD 1 is waterproof, dustproof, rustproof, and even shockproof, making it a highly robust speaker that can be used in a wide range of locations without fear of it getting easily damaged. It's so compact it could fit in almost any bag, but also, thanks to the adjustable strap, it’s easy to carry with you. And, as the ULT FIELD 1 can be placed either horizontally or vertically, you’ll always get the best sound performance, regardless of where you put it.

With a 12-hour battery life, you can keep the music playing all night long.

The ULT FIELD 1 can be used as a speaker phone for hands-free calls, you can pair it with a matching speaker to work as a single audio system (with one speaker acting as the left channel and the other as the right), and it even has Fast Pair technology, so you and your friends can quickly pair to the speaker to share your music.
