Short answer: the W-King T11. It ranks #35 of 73 boombox speakers by sound quality at $150; the Sony ULT Field 7 ranks #40 and costs $400, so there is not much of a tradeoff to weigh.
What the W-King T11 offers: 100W RMS output with 240W peak power, 112dB max volume, IPX6 waterproof, 10-hour battery life, power bank function, dual 5.25-inch woofers with tweeters and passive radiators, EQ with multiple modes, microphone and karaoke input, MicroSD and USB playback, TWS stereo pairing Watch for: Almost as deep of bass as the top ranked ones. A little hollow sounding. Wall wart charger.
What the Sony ULT Field 7 offers: Better sounding than the XG500 Watch for: Still not as deep bass as the top ranked speakers. 8khz peak
Buy the W-King T11. It ranks higher for sound quality than the Sony ULT Field 7 and costs less, so the other one has nothing left to offer.
There is a real battery-life gap here: the Sony ULT Field 7 is rated for 30 hours, the W-King T11 only 10 hours.
