Sony ULT Field 3 Black
Score: 79/100Rankings
The Bose SoundLink Flex combines IP67 durability with PositionIQ adaptive sound and up to 12 hours of playback, featuring a built-in mic and party-mode capabilities. Its modest bass and occasional short battery life are trade-offs. Suited for outdoor adventurers who value smart features and ruggedness.
Sony's ULT Field 3 is a rugged, IP67-rated portable speaker featuring powerful bass boost, 24 hour battery life, and integrated party lighting. Its substantial weight and reduced runtime under high-boost settings can be drawbacks. Perfect for outdoor parties and bass-focused listening.

Professional reviewers consider the SoundLink Flex a solid, well-balanced portable speaker with premium build quality and useful features like PositionIQ and SimpleSync, but they criticize its modest bass, lack of true stereo without a second unit, and battery life that falls short of the advertised claim.
Everyday users generally appreciate the speaker's ruggedness, portability, and clear sound for its size, while repeatedly mentioning shorter-than-advertised battery life and the need for a second speaker to achieve true stereo as the main drawbacks.
“No cons reported”
“deep, booming bass”
Professional reviewers commend the ULT FIELD series for its industry-leading bass boost, robust IP67 durability, and versatile Party Connect system, while noting that battery life is condition-dependent and the larger FIELD 7 model is notably heavy for a portable speaker.
Everyday users love the deep, booming bass, long battery life, and rugged waterproof design, often highlighting the fun party lights and easy portability; recurring complaints focus on reduced battery runtime at high performance settings, occasional Bluetooth glitches, and the weight of the biggest model.
