Sony SRSULT50W.CE7 Wireless Bluetooth Portable Speaker

Sony SRS-ULT50 / ULT Field 5 Wireless Bluetooth Portable Speaker – Party-Ready Bass, Lights & Rugged Durability

The Sony ULT Field 5 (model SRS-ULT50/ULT50) blends high-power sound, striking lighting effects and tough, outdoor-friendly construction so you get a speaker that performs wherever you take it. Designed for those who want more than just background music, it delivers boosted bass, clear audio, and long battery life, making it perfect for parties, outdoor adventures or simply filling your room with immersive sound.

At its heart sits a 2-way speaker system: a large X-Balanced woofer flanked by dual tweeters, matching them with side passive radiators to deepen bass without muddying highs. You can switch between two ULT Bass modes to favour either deeper low frequencies or more punchy, energetic sound depending on what style of music you like.

Battery performance is strong, offering up to 25 hours of play on a full charge. If you're running low, a quick charge gives you substantial playtime in just 10 minutes. It uses Bluetooth 5.3 for fast, reliable wireless connections and multipoint pairing so you can switch easily between two paired devices.

The ULT Field 5 doesn’t just deliver sound—it adds atmosphere with built-in 360° Party Lights on both ends that pulse with the music. It includes a removable shoulder strap so it’s easy to carry between rooms or outdoors. Constructed to withstand the elements, it's rated IP67 for water, dust and rust resistance, making it suitable for poolside, garden or beach use.

It can also double as a power bank via its USB-C port so you can charge a phone in a pinch, and it’s designed for both upright and horizontal use so you can fit it to your space. A 10-band EQ in Sony’s Sound Connect app lets you tailor the sound, while features like Party Connect allow stringing multiple speakers together for synchronized audio.

Weighing about 3.3 kg and with dimensions of roughly 320 × 144 × 125 mm, it’s substantial enough for big sound yet portable enough to take with you.
