Short answer: the Bose Soundlink Mini for better sound quality, the Sony ULT Field 1 for the lower price. The Bose Soundlink Mini ranks #56 of 136 medium speakers at $125. The Sony ULT Field 1 ranks #76 at $98, $27 cheaper.
What the Bose Soundlink Mini offers: Compact aluminum build feels sturdy and dense. Comes with a charging cradle. Watch for: Boosted upper bass like most Bose speakers. Upper treble rolled off. Bass doesn’t go as deep as others. Failures of the mainboard are common.
What the Sony ULT Field 1 offers: IP67 rated, survives drops and 1m submersion. Real-world battery around 28+ hours with ULT (bass boost) mode off. Stereo-pairs with a second ULT Field 1. Watch for: Upper midrange peak, rolled off treble
Buy the Bose Soundlink Mini if sound quality is the priority over the price, or the Sony ULT Field 1 if the price is the priority over sound quality.
There is a real gap in water resistance: the Sony ULT Field 1 at IP67 (brief submersion) against the Bose Soundlink Mini, which has no water resistance.
