Frequency is one of the most important parameters when choosing headphones. Generally, the higher frequency range of headphones, the better sound quality. The lower limit of the frequency range deals with bass reproduction. Frequency is measured in Hertz (Hz).

Sensitivity is measured in decibels per milliwatt, or dB/mW, and describes the sound pressure level. Generally, the higher the sensitivity, the better the headphones are for sound reproduction. A higher value also indicates higher volume.
An electrical parameter expressing resistance circuits in headphones in ohms. Headphones with lower impedance have a higher volume (important for portable media players), but greater distortion. Larger impedance equals lower volumes and lower distortion.
