Wired Earphone With High Sound Quality And Effective Anti-Jamming

Frequency Response

The frequency response range refers to the width of the frequency band that the earphone can send. The frequency response range of the high-fidelity earphone in the International Electrotechnical Commission IEC581-10 standard cannot be less than 50Hz to 12500Hz. The frequency response width of the excellent earphone can reach 5Hz-45000Hz, and the human ear The hearing range is only 20Hz-20000Hz. It is worth noting that the standards for defining the width of the frequency response are different, for example, if it is lower than 1/2 of the average output amplitude or lower than 1/4 as the standard, this is obviously different. The general manufacturer measures the frequency response

width with the output amplitude reduced by 1/2 as the standard, which means that the -3dB is the standard, but due to the different test standards used, some products are measured with -10dB as the standard. This is actually a standard measurement equal to 1/16 lower than the normal value. Therefore, the frequency response width is greatly expanded. Users should pay attention to the frequency response width of different brands of headphones may have different test standards when purchasing.

Sensitivity

The sound pressure level that the earphone can emit when the power of 1 milliwatt is input to the earphone (the unit of sound pressure is decibels, the greater the sound pressure, the greater the volume), so generally the higher the sensitivity and the lower the impedance, the easier the earphone will produce. The easier it is to drive. The sensitivity of the earphone refers to the amount of power that the sound source needs to input under the same loudness, that is to say, when the user sounds the same sound, the higher the sensitivity of the earphone, the lower the input power of the sound source. For portable devices such as walkmans, the higher the sensitivity, the easier it is to drive the headset.

The appearance and lightness of the earphone are like earplugs, and the pronunciation unit extends into the ear canal, which is closer to the eardrum than the earplugs. Has excellent sound insulation (up to 32 decibels). Originally for stage performers, it was later developed for general audio enthusiasts without the need to match the shape of the ear canal. Some mid-to-high-priced in-ear earplugs also come with a variety of earpieces of different sizes and materials, so they can better fit the ear canals of different shapes and make the user more comfortable to wear.
