Sound quality

1.lowest frequency

20Hz

40Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
2.highest frequency

20000Hz

20000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.has passive noise reduction

This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.
5.sound pressure level

100dB/mW

90dB/mW

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

32 Ohms

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.

Power
