2.lowest frequency

18Hz

Unknown. Help us by suggesting a value. (SoundMagic P23BT)

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

22000Hz

Unknown. Help us by suggesting a value. (SoundMagic P23BT)

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
5.impedance

18 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.
6.sound pressure level

108dB/mW

100dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
7.has a neodymium magnet
