Abstract
A device and method for adjusting an output to an audio port based on a determined sensitivity is provided. The device comprises a processor, an audio port, and an electrical measurement device configured to measure electrical properties of an external device plugged into the audio port over a range of frequencies. Using the electrical measurement device, one or more electrical properties of the external device plugged into the audio port are measured at a plurality of frequencies. A sensitivity of the external device is determined using the one or more electrical properties of the external device measured using the electrical measurement device. An output to the audio port is adjusted based on the sensitivity.
