Short answer: the Sonos Roam 2 favors neutral everyday listening and the Sonos ecosystem, while the Sony ULT Field 1 is the tougher, far longer-running outdoor speaker. Sonos is ranked 85 of 157; Sony is 90 of 157.
The Roam 2 keeps a balanced sound and makes pairing easier with its dedicated button, but it is effectively unchanged sonically from the original Roam. It is mono, has limited bass reach, and can distort when its bass is pushed.
Sony gives the ULT Field 1 IP67 protection, drop resistance, stereo pairing, and more than 28 hours of real-world battery life with ULT mode off. Its upper-midrange peak and rolled-off treble keep it from being the most natural-sounding option.
Sonos Roam 2 vs Sony ULT Field 1 separates Sonos integration and neutral tuning from Sony’s tougher, longer-running outdoor design. Sonos ranks 85 of 157, compared with Sony at 90 of 157.
The Roam 2 retains the original’s neutral balance and simplifies pairing with a dedicated button, although bass extension remains limited. Sony’s IP67, drop-resistant Field 1 has recorded more than 28 hours of battery with ULT off and supports stereo pairing, but its upper-mid peak and subdued treble make it less even sounding.
Buy the Sonos Roam 2 if a small neutral speaker for an existing Sonos system is the priority.
Buy the Sony ULT Field 1 if durability, battery life, and stereo pairing matter more.
