With the values above, the result is F
In this case, τ

in
This value is sufficient with regard to the previous formula, thus we can state that the pop is
imperceptible.
Connecting the headphones
Generally headphones are connected using jack connectors. To prevent a pop in the
headphones when plugging in the jack, a pulldown resistor should be connected in parallel
with each headphone output. This allows the capacitors C
headphones are not plugged in.
Pulldown resistors with a value of 1 kΩ are high enough to be a negligible load, and low
enough to charge the capacitors C
Note:
The pop&click reduction circuitry works properly only when both channels have the same
value for the external components C
