Earphones Specification Explained?

It is always best to listen to the song played carefully to make up your mind about buying a new pair of earphones but understanding the earphones specifications is also important.

IMPEDANCE

Impedance is electrical resistance that all earphones will have on the audio device. It is measured in ohms. Every portable earphone has impedance. It works as an opposition to the current flow. It is measured in Ohms. Higher the impedance less current will flow and the less sound level is produced. It is preferred to have less impedance. High impedance earphone works great with the devices carrying high amplifiers which is not possible for the portable devices it doesn’t have an inbuilt amplifier thus you should buy one with low impedance if you are looking to connect with any portable devices.

FREQUENCY RESPONSE

Frequency response is the range of frequency that an earphone can produce normally it is between 20 HZ – 20000 Hz. If you want more bass you have to choose earphone with wider frequency range.

SENSITIVITY

Sensitivity is the amount of sound decibels an earphone can produce for one milliwatt of the electrical signal. Higher the sensitivity higher the sound you could hear. Sensitivity of an earphone range from 80dB to 110dB.You should try buying an earphone with high sensitivity to minimize the power usage, which helps in longer battery life.
