FAQs

The Sony ULT Field 5 is built for people who want serious, room-filling sound in a speaker they can take anywhere. At the heart of it is Sony’s ULT POWER SOUND technology, a dedicated bass-boosting system activated by a single button press that delivers deeper, more powerful low-end without distorting the rest of the audio. Add to that IP67 waterproof and dustproof protection, 25 hours of battery life, synced LED party lights and a detachable shoulder strap and you get a speaker that’s equally at home at a garden party, a beach day or a large indoor gathering.

The ULT button on the Sony ULT Field 5 engages Sony’s bass enhancement processing and there are 2 levels to choose between. ULT1 adds a fuller, warmer low-end that suits most music genres, ideal for everyday listening or background music at a gathering. ULT2 cranks the bass up further for a more impactful, party-ready sound that can fill a large room or outdoor space. Reviewers consistently describe it as punchy, clear and powerful, making it noticeable even at distance.

Enjoy up to 25 hours of playtime on a single charge with the LED lights turned off, enough to keep a party going all day and well into the night. With the Party Lights on, expect around 10 hours of playback, which is still more than enough for a full evening’s entertainment. When the battery does run low, quick charging means just 10 minutes of plugging in via USB-C delivers around 100 minutes of playtime. There’s also a Stamina mode that disables the lights and ULT effects to extend battery life further when needed.

The ULT Field 5 carries an IP67 rating, meaning it’s fully dustproof and can be submerged in up to 1 metre of water for up to 30 minutes without damage. On top of that, the speaker is rust-resistant, making it a solid choice for poolside use, beach days or outdoor events where it might encounter rain. It’s built to handle the unexpected, so you can focus on the music without worrying about the weather or the odd accidental splash.

Yes, the USB-C port on the ULT Field 5 works both ways. As well as charging the speaker itself, it can be used to charge other tech like your smartphone or tablet when you’re out and about. This makes it a practical companion for longer days away from the mains, keeping both the music and your other devices powered up when you need them most.

The ULT Field 5 features 360° LED lighting that pulses and syncs with the rhythm of your music, adding a visual element to your listening experience that’s especially effective in the evening or indoors. The lights can be adjusted in intensity or switched off completely using the dedicated Light button on the back of the speaker. There’s also a Battery Care option on the same panel that caps charging at 90% to help preserve long-term battery health, a thoughtful touch for those who charge regularly.

Yes, the Party Connect feature lets you wirelessly pair multiple compatible Sony speakers together to create a bigger, more powerful sound across a wider space. This is ideal for larger gatherings, garden parties or events where a single speaker might not fill the room. You can also pair 2 ULT Field 5 speakers in stereo mode for a left and right channel experience. Compatible speakers include others in the ULT FIELD range.

Yes, in addition to Bluetooth, the ULT Field 5 includes a 3.5mm AUX input so you can connect a wired audio source directly. This is particularly useful if you want to plug in a device that doesn’t have Bluetooth or simply prefer a wired connection for reliability. The Bluetooth connection supports hi-res audio codecs, meaning you can stream high-quality audio wirelessly without losing detail for compatible sources.

On-device controls let you adjust volume, switch between playback modes, toggle the ULT bass effect and manage the Party Lights directly from the speaker. For more detailed audio customisation, the Sony Sound Connect app gives you access to a 10-band equaliser, dual-device Bluetooth pairing and DJ-style sound effects. The speaker can be positioned either horizontally or vertically depending on your setup, a small but practical touch for flexible placement at home or on the go.

The ULT Field 5 weighs 3.3kg and measures approximately 32 x 14.4 x 12.5cm, making it one of the larger portable speakers in its class, but a detachable shoulder strap makes carrying it comfortable over longer distances. It’s best thought of as a speaker you take to an event or a gathering rather than one you pop in a bag for a walk, but for its power output and feature set, it’s impressively self-contained. The combination of IP67 durability, long battery life and shoulder strap means it handles wherever the day takes you.
