Short answer: the W-King D8 Mini, though neither ranks well in its class. It ranks #136 of 179 medium speakers by sound quality, rated 2.6/5, at $49.99. The DOSS Soundbox Pro ranks #171, rated 2.1/5, at $29.99, $20 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 179 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The W-King D8 Mini is the better-sounding pick. An inexpensive water resistant stereo speaker with indoor and outdoor sound modes and a long rated battery. It charges over USB-C rather than Micro USB. The catch: Recessed midrange, harsh treble.
The DOSS Soundbox Pro is the lighter option. An inexpensive water resistant stereo speaker with an extra bass button, LED lights, a long rated battery and an aux input. At 1.2 lbs (558 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). The catch: Barely any bass.
Buy the W-King D8 Mini. It is rated higher for sound quality, and the $20 saving on the DOSS Soundbox Pro is not enough to make up the difference.
