Short answer: the W-King T9 Pro. It ranks #35 of 50 party speakers by sound quality at $171.49; the Sony GTK-XB72 ranks #47 and costs $349, which makes this an easy call rather than a real tradeoff.
What the W-King T9 Pro offers: 250W peak power, 120dB sound output with dual 6.5” woofers + dual 2.5” tweeters. Removable rechargeable battery allows continuous play via battery swapping. 12 custom bass settings for EQ adjustments by music genre. Music-synchronized LED lights (ambient to high-energy strobes). True Wireless Stereo for stereo pairing. Bluetooth 5.3, great customer service. Watch for: Sounds warm, somewhat gritty, not as detailed as higher ranked speakers
What the Sony GTK-XB72 offers: Exceptional sound quality, powerful bass, vibrant multi-colored LED lights. ClearAudio+ and Extra Bass technology for dynamic sound. LIVE SOUND button with angled speakers and DSP for 3D sound experience. FM radio, USB, RCA inputs with Music Center app control for lighting effects and EQ. Easy to use with convenient Bluetooth and FM radio. Watch for: No deep bass at all, weird midrange peak, rolled off treble and overall strange tuning
Buy the W-King T9 Pro. It ranks higher for sound quality than the Sony GTK-XB72 and costs less, so there is no real case for the other one.
Skip the Sony GTK-XB72 if sound quality matters to you. It ranks near the bottom of the 50 party speakers.
There is a real battery-life gap here: the Sony GTK-XB72 is rated for 23 hours, the W-King T9 Pro only 12 hours.
