Click-and-Pop Suppressors

Click-and-pop suppressors provide click-and-pop elimination for DEVICES such as CODECs with integrated headphone amplifiers that lack a clickless/popless startup/power-up or shutdown/power-down. Adding a click-and-pop suppressor is a cost-effective solution to click-and-pop problems caused by non-DirectDrive headphone amplifiers.
