Short answer: the Harman Kardon Onyx Studio 8 for better sound quality, the W-King X10 for the lower price. The Harman Kardon Onyx Studio 8 ranks #10 of 73 boombox speakers at $159.99. The W-King X10 ranks #62 at $80, $79.99 cheaper.
What the Harman Kardon Onyx Studio 8 offers: Warm sound with boosted bass. Watch for: Not as loud as others. No water rating.
What the W-King X10 offers: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ with indoor/outdoor modes, dual woofers with tweeters and passive radiators, Bluetooth 5.0 with 100ft range, MicroSD and USB playback, AUX input, TWS stereo pairing Watch for: Heavily rolled off treble, less bass than the top ranked.
Buy the Harman Kardon Onyx Studio 8 when sound quality outweighs the price for you, and the W-King X10 when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the W-King X10. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
There is a real battery-life gap here: the W-King X10 is rated for 42 hours, the Harman Kardon Onyx Studio 8 only 8 hours.
If water resistance matters to you, the W-King X10 at IPX6 (powerful water jets) holds up far better than the Harman Kardon Onyx Studio 8 at no water resistance.
