Sony SRSULT30B.CE7 ULT Wireless Bluetooth Speaker

Sony ULT-Field 3 (SRS-ULT30B) Wireless Bluetooth Speaker – Rugged Power in a Hand-Held Design

The Sony ULT-Field 3 is built for people who want bold, room-filling sound in a speaker that’s tough enough to go anywhere. With a 2-way speaker layout that combines a dedicated woofer and tweeter, it delivers more detailed mids and crisp highs while passive radiators on either side boost low frequencies. When you press the ULT button you get a bass-boost mode that makes the low end deeper and more impactful without completely overwhelming the rest of the mix.

Boasting up to 24 hours of battery life, the ULT-Field 3 lets you go nearly a full day of music on a single charge. A quick 10-minute top-up gives about 120 minutes of playback, so when you’re in a hurry this speaker keeps up. It’s rated IP67 for waterproofing, dust protection, and shock resistance, meaning it can handle spills, rain, dust storms, or beach sand. The detachable shoulder strap and relatively light weight make it easy to carry either by hand or sling it across your body.

Dimensions come in at approximately 10.08 inches (width) × 5.24 inches (height) × 3.11 inches (depth), with a weight around 1.2 kg (≈2.7 lb), making it compact yet roomy enough to produce powerful sound. Controls include physical buttons for power, play/pause, Bluetooth, volume, and the ULT mode, along with a Connect button to link to up to 100 compatible Sony speakers via Party Connect, or pair two units for stereo sound. The USB-C port handles charging, and even allows the speaker to act as a power bank for other devices.

Noise-aware features include sound field optimisation which adjusts output depending on ambient noise, echo-cancelling microphone for clearer calls, and a 7-band equaliser via the Sony Sound Connect app so you can tune the sound to your preference. All told, the ULT-Field 3 balances portability, durability and sound punch in a way that makes it a very strong option for outdoor use, parties, or simply enjoying music anywhere in and around your home.
