Omnidirectional Durable Wired Earbuds With Volume Control
Portable Wired Headphone With Shallow In-Ear No Swelling For Phone
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.

Impedance
Pay attention to the difference between the meaning of resistance. In the world of direct current (DC), the effect of objects on the current is called resistance, but in the field of alternating current (AC), in addition to resistance hindering current, capacitance and inductance also hinder current Flow, this effect is called reactance, and what we call impedance is the sum of resistance and reactance in a vector. Headphone impedance is the
abbreviation for AC impedance of headphones. Headphones with different impedances are mainly used in different occasions. On desktop computers or power amplifiers, VCD, DVD, TV and other machines, high-impedance headphones are usually used, and some professional headphones have an impedance of 200 Above ohm, this is to match the headphone jack on professional machines. For a variety of portable players, such as CD, MD, and MP3, low-impedance headphones are generally used, and these low-impedance headphones are generally easier to drive. But there are some professional-grade headphones that have lower impedance and are easier to drive.
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.
