Headphones have excellent performance and strong anti-falling ability, but they are large in size and inconvenient to carry and are suitable for use in fixed places such as home or office. Earplug headphones are small, portable, sound quality is good, sound interaction is strong, but low frequency loss is large; earplug headphones are integrated with headphones and ears. The advantages of plug style, fashionable appearance, popular with young people.
impedance
Headphones with different impedance are used in different situations. High impedance headphones are usually used on desktop, power amplifier, VCD, DVD, TV and other machines; low impedance headphones are generally used for various portable walkman, such as CD, MD and MP3.
Frequency Response
Refers to the width of the frequency band that headphones can emit. The frequency range of high-fidelity headphones in IEC 581-10 standard is 50 Hz-12 500 Hz.
sensitivity
It refers to the input power of the sound source under the same loudness. For portable devices such as Walkman, the higher the sensitivity, the easier the headphones to drive.
Harmonic distortion
The smaller the distortion, the better the sound quality.
We need to remind you that technical parameters are only one aspect when choosing and purchasing. When purchasing, we should treat technical parameters more rationally.
