Short answer: the JBL Xtreme 2 on measured sound quality, the W-King D9 on price. The JBL Xtreme 2 ranks #44 of 77 large speakers at $149.99. The W-King D9 ranks #65 at $71.24, $78.75 cheaper.
What the JBL Xtreme 2 offers: Four drivers with refined bass balance, closer to studio monitors than typical portables. IPX7 water-resistant. Amazing real-world battery: ~20 hours at 75dB (vs 15hr claim). USB-A port charges other devices. Optional carry strap. Watch for: External AC power brick for charging. Boosted bass. Treble harsh at high volumes.
What the W-King D9 offers: 60W RMS output, 106dB max volume, exceptional 40-hour battery life, power bank function, IPX6 waterproof, MicroSD and AUX support, dual drivers with passive radiators, Bluetooth 5.3, USB-C charging, EQ button, shockproof design Watch for: Very rolled off treble.
Buy the JBL Xtreme 2 when sound quality outweighs the price for you, and the W-King D9 when the price outweighs sound quality instead.
The W-King D9 is not a sound-quality pick. It sits near the bottom of the 77 large speakers; there are better options higher up.
Battery life favors the W-King D9: rated for 40 hours against 15 hours for the JBL Xtreme 2.
