7. sound pressure level

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

8. highest frequency

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

9. lowest frequency mic

The lowest frequencies that the mic can pick up well. Better for recording bass. If a microphone is going to be used for speech, a voice microphone, it must have great gain for bass, since human voice is in the low frequencies.

10. impedance

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.

11. driver unit size

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

12. has stereo speakers

Devices with stereo speakers deliver sound that surrounds the user from left and right side, creating a richer sound and a better experience.
