Short answer: the Bose SoundLink Max on measured sound quality, the W-King D9 on price. The Bose SoundLink Max ranks #17 of 77 large speakers at $399. The W-King D9 ranks #65 at $71.24, $327.76 cheaper.
What the Bose SoundLink Max offers: IP67 rated - dustproof and waterproof to 1m. Up to 20 hour battery; real-world testing found 43+ hours. Deep, rich bass with neutral tuning, app EQ. USB-C doubles as device charger. Sturdy carry handle. Watch for: Big peak in the upper bass, dipped midrange and lots of peaks and dips above the midrange. Bass not as deep as a Boom 2. Gets distorted above 80%. Self drains the battery about 20% a week.
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 Max 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 20 hours for the Bose SoundLink Max.
