2.weight

Unknown. Help us by suggesting a value.

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
6.sound pressure level

Unknown. Help us by suggesting a value.

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

Unknown. Help us by suggesting a value.

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.
