If your JBL speaker produces distorted sound, see the JBL Charge 3 Sounds Distorted problem page for possible problems and solutions. I think the speakers are being overpowered. I took my charge 3 apart and just watched the speaker as it was being used and saw no blown parts and no loose seals, but when I touched the positive lead wire that connects the red wire to the underside of the cone part of the speaker the static instantly cleared up and came back soon after I remove my finger. Did this multiple times and got the exact same result every time. So either the power needs to ramp down, the wire needs to be coated, or the speakers need to be grounded.
