The calculator below converts headphone efficiency to sensitivity or vice versa for the specified headphones. Since headphone impedance

- Enter the headphone impedance Rphones in ohms.

- To convert sensitivity to efficiency, enter the sensitivity value (dBSPL / 1Vrms) and click Get Efficiency.

- To convert efficiency to sensitivity, enter the efficiency value (dBSPL / 1 mW) and click Get Sensitivity.
