Short answer: the Bose SoundLink Revolve (Series II). It ranks #51 of 150 medium speakers by sound quality, rated 3.6/5, at $194. The Sony ULT Field 1 ranks #86, rated 3.1/5, at $138, $56 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Bose SoundLink Revolve (Series II): RTINGS measured a fairly neutral sound with a balanced midrange, so vocals and lead instruments come through clearly, and excellent directivity from the 360° design for an open, even sound around the room. Watch for: RTINGS found it lacks low bass, so there’s little deep thump or rumble.
The case for the Sony ULT Field 1: IP67 rated, survives drops and 1m submersion. Watch for: Upper midrange peak, rolled off treble.
Buy the Bose SoundLink Revolve (Series II). It is rated higher for sound quality, and the $56 you would save on the Sony ULT Field 1 does not close the gap.

The Two Speakers In Full
Bose SoundLink Revolve (Series II): $194.00 Amazon eBay
Older model: the Bose Soundlink Revolve (ranked lower, rated 3.5/5).
Pros: RTINGS measured a fairly neutral sound with a balanced midrange, so vocals and lead instruments come through clearly, and excellent directivity from the 360° design for an open, even sound around the room. In a side by side test against the Revolve+ II and B&O Beosound A1 2nd gen, several listeners preferred its clearer, less bass heavy tuning to the Revolve+ II. Up to 13 hours of battery, IP55 dust and water resistance, a built-in microphone for calls and voice assistants, and multi-connect for two devices at once.
Cons: RTINGS found it lacks low bass, so there’s little deep thump or rumble. It doesn’t get loud either: DXOMARK measured only about 73 to 74 dBA at maximum volume, against 85 to 89 dBA for speakers like the Sony SRS-XB43 in the same test, and bass compresses and pumps as you turn it up. There is no EQ in the Bose Connect app, a single unit plays mono, and it still charges over micro USB.
