Expand the Sound
If a casual hang turns into a full-fledged party, you can expand the soundstage with additional speakers. Pickup a second ULT FIELD 5 and you can use Stereo Pair to link them both wirelessly for true stereo sound. To cover even more ground, link up to 100 compatible speakers via Party Connect and a press of the speaker's Connect button.
All Day Power
The built-in battery of the ULT FIELD 5 can provide up to 25 hours of playback on a full charge. If you're in a rush on a low battery, a quick 10-minute charge will give you up to 2 hours of play time.
Share with Multipoint
Multipoint lets you pair two Bluetooth devices at the same time. It's a great way to share music selection with a friend or access a larger library of tracks on a laptop.
Doubles as a Power Bank
The USB-C port used to charge the ULT FIELD 5 can also be used to output power to a mobile device, such as a smartphone or tablet, using the speaker like a large power bank.
Sound Connect App
Managing the speaker is easy with a mobile device and Sony's Sound Connect app. With it you can adjust the 10-band equalizer to dial in your musical preference, control playback, adjust lighting, check on the battery status, view recent listening history, and more.

[This review was collected as part of a promotion.] This speaker has great sound and volume. It stays charged for a long time and has a backpack strap for easy use on the go. We recently went to the beach and this was the perfect item to have! It also looks really cool and sleek - I have it displayed on my TV console. Love love love!

Highest quality speaker Sony has ever released

[This review was collected as part of a promotion.] Best speaker I’ve ever used ! Amazing for music and movies as well, it was super easy to setup! It came with an instruction manual to help you through the process and has over two features of audio between bass boosted and non bass boosted, definitely worth the money I’ve never had such an amazing speaker before. Sony never disappoints ! It’s also portable and features a strap for you to carry along with you offering a transport style feature so you can bring it on the go!
