Design

1.has stereo speakers
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
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
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
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
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.weight

290g

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.can be folded
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
Foldable devices are easier to transport and take up less storage space.
6.has a tangle free cable
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
The cable is designed to minimize tangling.

Sound quality

1.lowest frequency

5Hz

9Hz

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

35000Hz

41500Hz

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

96dB/mW

108dB/mW

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

32 Ohms

150 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.
5.has a neodymium magnet
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

Connectivity

1.Can be used wirelessly
Beyerdynamic DT 990 Edition
Sennheiser HD 660 S
Wireless devices allow users more freedom of movement.
2.has a 3.5mm male connector
Beyerdynamic DT 990 Edition
