Design

1.has an over-the-ear form
Koss Pro4S
Comfortable full-size form with earcups that fully enclose your ears. This model is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors. It offers potential for maximum bass and loudness levels.
2.has a detachable cable
Koss Pro4S
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
3.weight

181g

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.
4.can be folded
Koss Pro4S
Foldable devices are easier to transport and take up less storage space.
5.travel bag is included
Koss Pro4S
The device comes with its own special case or pouch, which is useful for safe transportation.
6.cable length

1.4m

A long cable ensures more freedom of movement.

Sound quality

1.lowest frequency

10Hz

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

25000Hz

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
Koss Pro4S
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

99dB/mW

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

35 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.
