HiFiMan Edition X Design Picture

The HifiMan Edition X stand out with their unusual design. They're incredibly comfortable headphones with a sturdy build quality. The ear cups, especially, feel durable and make use of premium materials. However, these are one of the biggest headphones we've tested so far. The ear cups easily cover a large area of your face, particularly on smaller heads. They're unstable, cumbersome and do not have any audio controls. Simply put, they're not made to use outdoors.

Style
HiFiMan Edition X Design Picture 2

HifiMan Edition X are uniquely designed headphones. They have a retro style headband and very large, flat and open ear cups. They look and feel premium and are superbly well-padded with a suede-like cushioned fabric. However, the sheer size of these headphones makes them awkward to wear in public. The headband also feels a little cheaply built compared to the level of care put into the ear cup design.

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.
:
1.16 lbs

The HifiMan Edition X deliver a comfortable listening experience. They're exceedingly well padded, with a suede-like material, that's soft and pleasant on the skin. The headband, although a little stiff is not too tight on your head. However, the size of these headphones could be bothersome for some listeners, and they're a little heavy even if the weight is well distributed.

HiFiMan Edition X Stability Picture

These are not sports-oriented headphones. They're big and bulky, and although comfortable, they're not stable enough on your head to use while doing any physical activity. The large and heavy earcups will sway and slip off your ears if used while running or exercising. On the upside, the cable is detachable in case it gets hooked on something.

Score components: Subjectively assigned
HiFiMan Edition X Build Quality Picture

The Edition X have an above average build quality. The open ear cups are dense, and the open-back design is reinforced with a sturdy metallic grid. The headband also has a relatively simple design with a metal frame, that's a little thin, but feels sturdy enough not to break under a fair amount of physical stress. Sadly, the joints that connect the frame to the ear cups is a little plasticky doesn't feel as durable as the rest of the design. This feels out of place on a headphone of this caliber. The cable on the other hand is thick and coated in a braided fabric that's durable.

HiFiMan Edition X Frequency Response

The HiFiMan Edition X sound great and reproduce tracks with remarkable fidelity. These headphones have low impedance, planar magnetic drivers, that can be powered by your phone. They deliver an even and punchy bass, an almost flawless representation of the mid-range and balanced high-frequencies which make instruments and vocals sound relatively crisp. They also have a very open design that creates a broad and spacious soundstage, ideal for critical listening.

9.7 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

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.

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.
Good value: >1dB
Noticeable difference: 0.3dB
:
-0.02 dB

Excellent soundstage. The large and deep drivers of these headphones outperform the HD 800 S in the PRTF test. This shows that these headphones activate the same pinna filters that a loudspeaker positioned 30 degrees in front would do, pulling out the soundstage from inside the head to the front. Also, these headphones are extremely open, and by far the loudest we have measured so far. This will help the music merge with the outside ambience, and at higher volumes even activate the ambient acoustics.

8.0 Imaging
Show Help
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.

Above average Imaging. Although the phase response is quite flat in the Bass and Mid ranges, there's a noticeable roll-off above 10KHz. It should be noted that that phase distortion at higher frequencies is quite hard to detect. Additionally, our test unit performed above average in driver matching tests.

The Edition X are open-back headphones and are not designed to isolate listeners. Openness is one of the key components of their superb sound quality, but this also makes them unusable in everyday settings. They will distract anyone near you even at low-to-moderate volumes and also don't block any noise from your surroundings.  They won't fare well in loud environments and are best used to enjoy high-res audio in private.
