Short answer: the Bose S1 Pro for better sound quality, the Sony GTK-XB90 for the lower price. The Bose S1 Pro ranks #16 of 50 party speakers at $699. The Sony GTK-XB90 ranks #46 at $429, $270 cheaper.
What the Bose S1 Pro offers: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 mic/line + 1 line/Bluetooth). Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Watch for: With full range music, it becomes distorted above ⅔ volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass.
What the Sony GTK-XB90 offers: Deep punchy EXTRA BASS technology for party use. 3x 2.36” tweeters + 2x 7.09” woofers, built-in LED lights sync with beat. 16 hours battery claimed (9 hours real-world at moderate volume with lights). Built-in handle, portable one-box design. Fiestable plugin controls party settings and DJ effects. Three-device simultaneous Bluetooth pairing. Watch for: Bass is muddy and not deep, weird midrange peak, rolled off treble and overall strange tuning
Buy the Bose S1 Pro if sound quality is the priority over the price, or the Sony GTK-XB90 if the price is the priority over sound quality.
The Sony GTK-XB90 is not a sound-quality pick. It sits near the bottom of the 50 party speakers; there are better options higher up.
