Koss QZPro Design Picture

The Koss Quiet Zone QZ-Pro have a lot of flaws in their design and are uncomfortable. The cable is non detachable and does not provide in-line controls except a volume slider which is dissapointing. The build quality is too stiff and feels cheap, especially the sliding mechanism, which is just awkward and frustrating to use.

Style
Koss QZPro Design Picture 2

The QZ-Pro look a little cheap. The two-tone color scheme is esthetically pleasing but the low-grade plastic and odd hinge reduces their appeal significantly. The matte, silver ear cups are circular and coated with a soft black padding. The headband is lightly padded but oddly shaped due to the hinge and may be a turn off for some.

Clamping Force
Show Help
What it is: The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters: The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
:

The Koss QZ-Pro are not very comfortable. The headband and earcup design is a little cumbersome and stiff and does not extend very well for larger heads. The ear cups, although decently padded, oddly do not provide a good seal, leaving gaps that feel uncomfortable and let sound leak in and out.

Button layout is very limited on the QZ Pros, with just one switch to activate the noise canceling. It's simple but looks and feels a little cheap. The audio cable, which is not detachable or interchangeable, only has a volume slider, which is disappointing.

The QZPro are somewhat portable. They have a unique folding mechanism that allows them to collapse into a compact format. However, they are one the larger side for over-ear headphones and will still take up quite a bit of space in a bag. They won't fit in a pocket and are too cumbersome to carry around on your person. They also do not come with a case or carrying pouch, which is disappointing.

Koss QZPro Build Quality Picture

Build quality is just passable. The QZ Pro look and feel cheap. The joints are made of dense plastic that feels moderately solid but also makes the hinges stiff. The headband, however, does not feel very solid and once on, adjusting the ear cups is very cumbersome. The sliding mechanism to extend the headband does not feel durable and does not extend very far. The padding on the ear cups and the headband is soft but looks susceptible to wear and tear.

Koss QZPro Frequency Response

The koss Quiet Zone QZPro disappoint with their audio reproduction. The bass does not pack enough punch but is overpowered compared to the muddy low-mids and terrible highs. They don't sound good with instrument-heavy tracks and are too hollow for bass-heavy music, which makes them ill-suited for most genres. The one upside is that distortion is low, even at higher volumes.

Poor performance. The lacking low-bass means that these headphones don't produce a lot of thump. On the other hand, the over-emphasized bass and high-bass add muddiness and boominess to the sound.

Terrible treble performance. The entire treble range is quite under-emphasized, resulting in a muffled, closed-up and lifeless sound.

6.5 Soundstage
Show Help
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Error
Show Help
What it is: The average amount of deviation in Pinna-Related Transfer Function of the headphones, compared to that of a loudspeaker. Whether the soundstage is perceived to be unnatural, located inside or in front of the head, is dependent on this quality. The more the headphones activate the HRTF resonances of the ear (similar to what loudspeakers do), the more the soundstage will be pulled out from inside the listener's head. This quality affects both stereo and mono content.
When it matters: When a natural, in-the-front soundstage is desired, similar to that of a loudspeaker.
Good value: <5
Noticeable difference: 0.5
:
5.18 dB
Openness
Show Help
What it is: How open the headphones are, and how open and spacious they sound. This quality affects both stereo and mono content. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score.
When it matters: When an open, wide and roomy sound is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.

Acoustic Space Excitation
Show Help
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones takes some of the characteristic of its environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality affects both stereo and mono content. This value is the inverse of the Leakage test score.
When it matters: When an open, wide and roomy sound is desired.
Good value: >7.5
Noticeable difference: 0.5
:
2.9
Correlated Crosstalk
Show Help
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.

7.7 Imaging

What it is: Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image, and how transparent the imaging is.

Isolation

Show Help
Score components:

The QZ Pro have disappointingly weak noise isolation performance. The active noise cancelling just generates a hiss that does nothing to block ambient noise from disturbing your listening experience. The poor isolation is not recommended for use in anything but a quiet environment. The placement of the earcups will make an imperfect seal certain heads. On the upside, they do prevent a fair amount of sound leakage if the fit is right.

When it matters: How suitable the power and wireless specifications of an active headphone will be, depending on your listening habits. The range and/or discharge time of the active headphone you select will be important if you're often on the move or have long uninterrupted listening sessions.
Score components:

The QZPro only have noise canceling as an active feature. This makes them less versatile for other use cases except as noise canceling headphones, as they lack both wireless features or an app, to enhance and customize their sound. On the upside, the AAA cell delivers up to 40 hours of continuous playback.

The Quiet Zone Pro can last up to 40 hours of continuous playtime at average volumes. This gives them an above-average battery life and means you won't have to change the triple AAA battery as often, which is great for long flights or road trips. Unfortunately, they do not have any battery saving features like an auto-off timer but can continue playing audio even when the battery is completely drained.
