Sony ULT Field 1 Waterproof Portable Bluetooth Speaker – Enhanced Bass, 12h Battery, IP67 (Off White)

Compact power, big presence

The Sony ULT Field 1 is a portable Bluetooth speaker that blends a compact silhouette with a surprisingly expansive soundstage. When you want more bite in the low end, the dedicated ULT bass boost brings deeper, more energetic bass without overwhelming the rest of the mix.

Immersive sound, tailored for any setting

Thanks to a sound diffusion processor and DSP technology, the ULT Field 1 delivers a wide, even listening field. It can fill a room, a balcony, or a campsite with clear detail and warmth, turning everyday listening into a fuller experience without needing a larger speaker.

Rugged by design, ready for any adventure

Built to withstand active lifestyles, this speaker carries an IP67 rating for dustproof, waterproof, rustproof, and shockproof performance. Its detachable multi-way strap adds carrying versatility, and you can choose from four colors—Black, Off White, Forest Gray, and Orange—to match your style.

Long-lasting battery, carefree listening

Up to 12 hours of playback means you can enjoy longer sessions—from beach days to hiking breaks or at-home workouts—without constant recharging. Real-world use may vary with volume and content, but the endurance is clear for extended days out.

Built-in features for everyday use

The integrated microphone includes echo cancelling for clearer calls, while Bluetooth pairing keeps setup simple and reliable across compatible devices.
