- Jul 05, 2018-

The main performance of the International Electrotechnical Commission IEC581-10 standard high-fidelity headphones is: frequency sound is not lower than 50Hz to 12500Hz; the allowable error of typical frequency response is ±3dB; the slope of the frequency response curve does not exceed 9dB without octave at 250Hz-800Hz The difference between the average sound pressure level of the inner left and right units in the same octave bandwidth is not more than 2dB, and the harmonic distortion is not more than 1% when the sound pressure level is 94dB in the range of 100Hz-5000Hz, and not more than 3% at 100dB; The frequency response is allowed to decrease between 2KHz and 5KHz to improve transparency and space.
