1.has stereo speakers
Ultrasone PRO 900
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
Ultrasone PRO 900
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
Ultrasone PRO 900
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.


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

Foldable devices are easier to transport and take up less storage space.
6.travel bag is included
Ultrasone PRO 900
The device comes with its own special case or pouch, which is useful for safe transportation.

Sound quality

1.lowest frequency


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


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
Ultrasone PRO 900
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.

40 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.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.
