Sony ULT Field 3 Wireless Bluetooth Speaker - Grey

The Sony ULT Field 3 is a portable wireless Bluetooth speaker designed to deliver powerful, bass-enhanced audio in a rugged, travel-friendly package. Its compact form factor incorporates a 2-way active driver system with a dedicated woofer and tweeter, supported by optimised side passive radiators that work to produce deep, punchy low frequencies. A dedicated ULT button allows users to instantly boost bass response, while ULT Power Sound mode provides enhanced audio performance for more demanding listening situations. The speaker's construction prioritises durability, with IP66 and IP67 ratings making it waterproof, dustproof, and shock-resistant, suitable for use by the pool, at the beach, or on outdoor adventures. Practical features include a detachable shoulder strap for multiple carrying options, a built-in microphone with echo cancellation for hands-free calls, and the ability to pair with two Bluetooth devices simultaneously. The USB Type-C port facilitates convenient charging and also allows the speaker to function as a power bank for charging other devices. Sony's Sound Connect app provides battery level monitoring and additional controls, while the hardware-based Party Connect feature enables linking up to 100 compatible speakers for synchronised audio without requiring an app. The speaker body incorporates recycled plastic materials, and the packaging avoids plastic use entirely, reflecting environmental considerations in its design. This speaker is well-suited for active individuals, outdoor enthusiasts, and social gatherings where robust, portable sound is needed. Its combination of substantial battery life—up to 24 hours of playback—and quick-charge capability (offering 120 minutes of use from just 10 minutes of charging) makes it reliable for all-day excursions. The salt-water resistance adds to its beach and poolside versatility, while the shockproof build ensures it can withstand the knocks of travel. Whether used for personal listening during activities like cycling or skating, or as part of a multi-speaker setup for parties, the ULT Field 3 balances audio performance with practical, adventure-ready durability.
