Score: 71/100
Sony ULT Field 3 Black
Score: 79/100Rankings

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.

The Bose SoundLink Color II is a compact, splash-resistant speaker featuring NFC pairing, built-in mic, and low-latency Bluetooth. Its shallow bass, modest volume, and limited 8-hour battery life constrain its use in larger settings. Suited for casual listeners who value portability and quick pairing.

Professional reviewers commend the SoundLink Color II for its pocket-size portability, robust Bluetooth performance with low latency, and rugged IPX4 silicone build. However, they consistently note that the acoustic performance is average, with weak bass extension, rolled-off treble and limited SPL, making it less suitable for listeners who prioritize deep, powerful sound.
Everyday users love how easy it is to toss the speaker into a bag and take it to the pool or gym, praising its splash resistance, simple controls and reliable Bluetooth. The most common criticisms revolve around thin bass, muted mids/treble and occasional pairing glitches, especially when trying to use multiple devices.

“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.
