Short answer: Sony ULT Field 1 is the rugged battery-life choice, while LG Xboom Grab offers similar weather resistance with straps and a slightly shorter runtime. Sony’s ULT mode-off endurance is outstanding, though its upper mids and treble are uneven; LG is not a bass leader and costs more than its performance warrants.
Buy the Sony ULT Field 1 if long real-world battery life and drop-ready IP67 protection are decisive.
Buy the LG Xboom Grab if its mounting straps fit your use better than Sony’s longer runtime.
If battery life is a priority, the LG Xboom Grab is rated for 20 hours versus 12 hours for the Sony ULT Field 1.
