Short answer: the Bose SoundLink Plus for better sound quality, the W-King D9 for the lower price. The Bose SoundLink Plus ranks #22 of 77 large speakers at $199.99. The W-King D9 ranks #65 at $71.24, $128.75 cheaper.
What the Bose SoundLink Plus offers: IP67 rated, IP67 water/dustproof. Close to 20 hour battery life. Vibrant sound with booming bass, clean mids. Bluetooth 5.4 with good range. Premium tactile grille, smooth silicone. Quality build at $269. Watch for: Boosted thuddy bass, but not as deep as the SoundLink Flex and you should probably just buy one of those instead if you want a Bose.
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 Bose SoundLink Plus if sound quality matters more than the price. Buy the W-King D9 if the price matters more than sound quality.
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 20 hours for the Bose SoundLink Plus.
