Audio-Technica ATH-M20x
Sennheiser HD 558
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has an over-the-ear form
Audio-Technica ATH-M20x
Sennheiser HD 558
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.
3.has a detachable cable
Audio-Technica ATH-M20x
Sennheiser HD 558
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.weight

190g

260g

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.
5.cable length

3m

3m

A long cable ensures more freedom of movement.
6.has a straight plug
Audio-Technica ATH-M20x
Sennheiser HD 558
A straight plug is better when the jack is on the top or bottom of your player.

Sound quality

15Hz

15Hz

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

20000Hz

28000Hz

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
Audio-Technica ATH-M20x
Sennheiser HD 558
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

96dB/mW

112dB/mW

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

47 Ohms

50 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.has a neodymium magnet
Audio-Technica ATH-M20x

Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

Audio-Technica ATH-M20x
Sennheiser HD 558
