Short answer: the Sony ULT Field 1. It ranks #76 of 136 medium speakers by sound quality at $98; the Sony SRS-XB30 ranks #104 and costs $199, which makes this an easy call rather than a real tradeoff.
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
What the Sony SRS-XB30 offers: IPX5 rated. Doubles as a power bank for charging your phone. Long claimed battery life (up to 24 hours at moderate volume). Watch for: Muffled sound, worse than a XB20
Buy the Sony ULT Field 1. It ranks higher for sound quality than the Sony SRS-XB30 and costs less, so the other one has nothing left to offer.
Skip the Sony SRS-XB30 if sound quality matters to you. It ranks near the bottom of the 136 medium speakers.
If battery life is a priority, the Sony SRS-XB30 is rated for 24 hours versus 12 hours for the Sony ULT Field 1.
