Our Verdict
Bose SoundLink Flex
Sony ULT FIELD 1
The Bose SoundLink Flex and the Sony ULT FIELD 1 are comparable speakers with different strengths. They have very similar sound profiles, with the Sony offering a bit more warmth out of the box. You can also tweak the Sony's sound using the graphic EQ in its companion app. On the other hand, the Bose doesn't compress your audio as much when you blast your tunes. Both speakers will work with your device's Google Assistant or Siri voice assistant, but the Bose does a much better job picking up your voice from afar or in a noisy room. The Bose also lasts a little longer, but battery life varies with usage.
