What the Sony SRS-XB20 offers: IPX5 rated pill shape slides easily into a bag. 12 hour battery life. Watch for: Sounds thin at higher volumes. Bass falls away quickly.
What the W-King D8 Mini offers: 30W output with switchable indoor/outdoor EQ modes. IPX6 rated with a 5000mAh battery. Watch for: Recessed midrange, harsh treble. Bass doesn’t go as deep as others.
