Short answer: the Sony ULT Field 1 for better sound quality, the W-King D8 Mini for the lower price, though neither ranks well in its class. The Sony SRS-XB20 ranks higher than the W-King D8 Mini (#120 vs #135 of 175 medium speakers) but is discontinued. Its replacement, the Sony ULT Field 1, is rated 3.1/5 at $138; the W-King D8 Mini is rated 2.6/5 at $49.99, $88.01 cheaper. Both are rated below 3.0/5 among the 175 medium speakers; for better sound, the EarFun Uboom L ranks #2 at $49.79.
The Sony SRS-XB20 is the lighter pick. At 1.3 lbs (590 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). The catch: Sounds thin at higher volumes.
The W-King D8 Mini is the longer-running pick. 30W output with switchable indoor/outdoor EQ modes. It is rated for 24 hours of battery against 12 for the Sony SRS-XB20. It has an adjustable EQ, which the Sony SRS-XB20 lacks. It charges over USB-C rather than Micro USB. The tradeoff: Recessed midrange, harsh treble.
Buy the W-King D8 Mini if price matters most. For better sound quality, the Sony ULT Field 1, the replacement for the discontinued Sony SRS-XB20, is rated higher but costs $138.
