JBL Flip 4 Black Bluetooth Speaker GG Model Original Owner Tested 5-Dot LED. This isn't just another used speaker. Rubberized Housing: The soft-touch rubber trim is firm and clean. While there are a few very minor surface "rub marks" on the outer rings (visible only under direct light), there is zero peeling or "stickiness"—a common issue with older JBL units.
