Headphones parameters

Monster Beats Justbeats Solo Purple

Parameter is judged a headset important data.

(1) Impedance: In addition to Monster Beats Solo the field in the AC resistance will impede the current outside the capacitor and inductor will also impede the flow of current, this role is called reactance, and the music scene and said impedance is the resistance reactor and on the vector. Namely: impedance = resistance + inductance capacitance resistance + resistance.

(2) Sensitivity: point to the headphone input 1 mW of power that can be issued when the headphones sound pressure level (dB sound pressure of the unit is, the greater the pressure the greater the volume), it is generally the higher the sensitivity, impedance more small, the more the more easy to drive headphones and sound.

(3) Frequency Response: the frequency corresponding to the sensitivity value is the frequency response, the range of human hearing can reach about 20Hz-20000Hz.
