Short answer: the Soundboks Mix for durability and linking, the W-King T9 Pro for raw output on a budget. The Mix is IP65 rated with 65W USB-C fast charging and TeamUp linking to five other SKAA speakers, but it manages only 72W from a single 10-inch woofer and can sound bright in the treble. The W-King puts 250W peak across dual 6.5-inch woofers, though it sounds warm and somewhat gritty.
Buy the Soundboks Mix when sound quality outweighs the price for you, and the W-King T9 Pro when the price outweighs sound quality instead.
Battery life favors the Soundboks Mix: rated for 40 hours against 12 hours for the W-King T9 Pro.
If water resistance matters to you, the Soundboks Mix at IP65 (water jets) holds up far better than the W-King T9 Pro at no water resistance.
