Short answer: the Flip 6, and the ranking gap justifies the premium. It ranks #13 of 179 medium speakers at $79.95; the D320 ranks #49 at $52.92, $27.03 less.
The D320’s feature list covers IP67 waterproofing, a 24-hour battery, and a customizable EQ app with six preset modes. Our notes describe the tuning as warm, lacking some detail, with rolled-off treble.
The Flip 6 is described as a huge sound quality leap over the Flip 5, very neutral and nearly pocket-sized, with only a slight upper mids emphasis as its real complaint.
Buy the Flip 6 for the meaningfully better sound. Buy the D320 if IP67 water resistance and the $27.03 saved matter more to you.
Battery life favors the W-King D320: rated for 24 hours against 12 hours for the JBL Flip 6.
