Koss QZ900
Sennheiser CX 300-II Precision
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
Koss QZ900
Sennheiser CX 300-II Precision
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
Koss QZ900
Sennheiser CX 300-II Precision
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.can be folded
Koss QZ900
Sennheiser CX 300-II Precision
Foldable devices are easier to transport and take up less storage space.
5.travel bag is included
Koss QZ900
Sennheiser CX 300-II Precision
The device comes with its own special case or pouch, which is useful for safe transportation.
6.has an in-ear form
Koss QZ900
Sennheiser CX 300-II Precision
The in-ear device is ultracompact and lightweight, with little or no interference with earrings, spectacles, hats, or hairstyles. It is inserted in the ear canal itself and blocks out a lot of environmental noise. It has stronger bass tones and is unlikely to fall out of the ear.

Sound quality

1.lowest frequency

20Hz

19Hz

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

21000Hz

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 QZ900
Sennheiser CX 300-II Precision
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.has active noise cancellation (noise control)
Koss QZ900
Sennheiser CX 300-II Precision
This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.
5.sound pressure level

100dB/mW

113dB/mW

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

32 Ohms

16 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.

Power

1.has a removable battery
