Sony SRS-ULT10W.CE7 ULT FIELD 1 - Wireless Bluetooth Portable Speaker with ULT POWER SOUND, 12hr Battery - White

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.  

Play Loud, Pack Light

Drawing on decades of Sony audio expertise, the ULT FIELD 1 has been designed to deliver a huge sound, from a small, portable body. Behind the grille, a powerful woofer combines with a high-quality tweeter to create impactful, detailed audio, and on either side of the speaker are two passive radiators to further enhance the bass.  You can play loud but pack light with the ULT FIELD 1.

Hit The Button. Feel The Bass

When you push the ULT Button, the ULT FIELD 1 steps up to the next level. The bass is boosted even further, while the sound pressure is increased to produce addictive, energetic ULT POWER SOUND whether you're at home, or on the move.

You can toggle the ULT mode by pushing the ULT button on the top of the unit, or directly through the Sony | Music Centre app.  

Anywhere, Any Weather

No need to worry about the ULT FIELD 1 if the weather turns and it gets wet. It’s IP67 rated, which means, waterproof. And as it’s dustproof and salt water resistant as well, you can enjoy music on the beach without worrying about the sea water or sand damaging the speaker. 

Protected from the Unexpected

The ULT FIELD 1 is shockproof, making it one of the most durable speakers available. Having undergone extensive shock testing to ensure it can withstand the inevitable knocks, bumps, and scrapes that come with everyday use, this portable speaker is perfect for anyone who just wants to enjoy their music and not worry if the speaker takes a hit.

Grab and Go

The ULT FIELD 1 may deliver big sound, but it’s small, light, and easy to carry with you. 

Weighing less than 0.7kg and only measuring around 20cm long, the ULT FIELD 1 will fit in almost any bag. It also has an adjustable carry strap, so it’s easy to carry or hang up. Conveniently, it’s designed to work both horizontally and vertically, so even when there’s not much space for the speaker, you still get the best sound experience.  

All-day Battery

This Bluetooth speaker has a fantastic battery life. It can keep the playlist going for up to 12 hours before needing to recharge, so you can enjoy music all day or night long. 

Crystal-clear Calls

As well as listening to music, you can use the ULT FIELD 1 as a speaker phone to make hands-free calls. It even includes Echo Cancelling technology, which means two people can talk at the same time without cutting each other off.  

Quick, Easy Pairing

It’s easy to pair to the ULT FIELD 1 with Bluetooth, but if using an Android phone, it’s quicker and simpler than ever before.

Fast Pair allows you to connect with an Android device by tapping on the pop-up screen that automatically appears on your Android device when you put the Bluetooth speaker into pair mode. Perfect if friends want to quickly connect to share their music.

If you, or someone you know, has a second ULT FIELD 1 speaker, using the Stereo Pair feature, you can pair them both together to work as one single sound system, meaning one speaker works as the left channel, and the other as the right.
