A method and computer program product for dynamically balancing the active noise cancellation value at a first and second earphone interface of a headphone device. The method enables determination of a first active noise cancellation value of an anti-noise output signal at a first interface. The method determines a second active noise cancellation value of the anti-noise output signal at a second interface. A comparison is made between the first active noise cancellation value and the second active noise cancellation value. In response to the first active noise cancellation value and the second active noise cancellation value being outside of a predetermined margin of each other, at least one adjustable parameter associated with the anti-noise output signal is dynamically adjusted to balance active noise cancellation values at the first and second headphone nterface.
