The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.sound pressure level
Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
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.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.
