Impedance (Impedance):
Daily said impedance is the resistance and reactance on vectors and. The smaller the impedance， headphones better. Typically 16Ω.

SPL pointing headphone input power of 1 milliwatt headset can be issued (decibels of sound pressure， the greater the volume the greater the sound pressure)， so generally the higher the sensitivity， the smaller the impedance， the more likely headphones loud， more easy to drive. General headset greater than 80db.
Frequency Response (Frequency Response):
Frequency corresponding to the sensitivity of the frequency response is， the image is drawn into the frequency response curve of the human auditory sense can be achieved in the range of about 20Hz-20000Hz， the headset is now mature technology have reached such a request.
