22000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.sound pressure level

114dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
4.impedance

32 Ohms

Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.
5.driver unit size

40mm

The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
