- Passive Soundstage
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.
Score components:
Learn more
PRTF
PRTF Accuracy (Std. Dev.)
What it is: The standard deviation of the PRTF (pinna-related transfer function) of the headphones compared to a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test doesn't apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: An accurate pinna activation is mainly responsible for how natural and speaker-like the soundstage is perceived to be. The less error in the shape of the PRTF, the more natural and speaker-like the perception of the soundstage will be. High amounts of error may indicate a soundstage that's unnatural or odd.
Good value: <2.5
Noticeable difference: 0.1
Learn more
PRTF Size (Avg.)
What it is: The average amplitude of the PRTF (pinna-related transfer function) of the headphones compared to that of a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test doesn't apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is responsible for the perceived size of the soundstage. The higher the value, the larger the perceived size of the soundstage. However, values above the reference (5.0dB) could result in a soundstage that's perceived as unnatural or odd.
Good value: >3.7
Noticeable difference: 0.1
Learn more
PRTF Distance
What it is: The depth of the "10kHz notch" of the headphone's PRTF, which is caused by phase cancellations at the concha. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is mainly responsible for the perceived distance and elevation of the soundstage. A small distance value may result in a soundstage that is perceived to be located inside the head. Larger values may help pull the soundstage out from inside of the head and bring it to the front.
Good value: >13
Noticeable difference: 1
Learn more
Openness
What it is: How open the headphones are, and how open and spacious they sound. This quality is monaural and can be perceived even with one ear. 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 and could be indirectly related to the acoustic impedance of the headphones.
When it matters: When a headphone with a sense of an open and spacious soundstage is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.
Good value: >7.5
Noticeable difference: 0.5
Learn more
Acoustic Space Excitation
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 will be affected by the environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality is monaural and can be perceived even with one ear. This value is the inverse of the Leakage test score.
When it matters: Headphones with higher excitation values, similar to openness, tend to have soundstages that are perceived as more open and spacious.
Good value: >7.5
Noticeable difference: 0.5
Learn more
- Virtual Soundstage
What it is: Whether the headphones have DSP-aided soundstage, and if so, what features they support.
When it matters: When you want a soundstage that resembles the soundstage of speakers in a room. This is useful for mixing and mastering applications, as well as listening for pleasure. It could also be useful for gamers so that they can locate sound in a 360/3D environment. Some headphones even support head tracking, which would be very useful for first-person shooter games.
Score components:
Learn more
Virtual Soundstage
Head Modeling
What it is: Head modeling is one of the key factors in creating an out-of-head soundstage. Ideally, you can optimize the binaural effects of the soundstage by entering your individual head measurements. If not, the average Head-Related Transfer Function (HRTF) for an adult human is used, which may not be optimized to your head.
When it matters: When you want a seamless, realistic, and out-of-head soundstage. If the default HRTF of the virtual soundstage doesn't match yours, you will perceive a shift in tonality rather than an externalized soundstage.
Learn more
Speaker Modeling
What it is: Speaker modeling is responsible for creating crosstalk and the perceived angle of the source.
When it matters: When you want a speaker-like and out-of-head soundstage. If you tend to find the standard 30° angle of stereo speakers too narrow, being able to adjust the width and angle of the modeled speakers will allow you to adjust the width of the soundstage.
Learn more
Room Ambience
What it is: Whether the headphones add room ambiance to the soundstage as part of creating a virtual soundstage.
When it matters: Having room ambiance is important for creating a realistic and speaker-like soundstage since we always listen to speakers in a room. This is especially important if you use headphones for mixing and want to mixes to translate well on loudspeakers.
Learn more
Head Tracking
What it is: Whether the position and orientation of the virtual soundstage follows your head movements and rotation.
When it matters: This is especially important for VR gaming, so that the soundstage rotates based on where you're 'looking'. However, this can be distracting for other uses like listening to music while walking outside.
Learn more
Virtual Surround
What it is: Whether the headphones have support for converting multi-channel content into 3D binaural audio for headphones.
When it matters: This would matter to you only if your music or video games are in a multi-channel format. This is becoming less and less important since Dolby Atmos for headphones is gaining prominence in video games and is available for a low cost (or free) on most platforms.

- Weighted Harmonic Distortion
What it is: The amount of subtle, unwanted frequencies (harmonics) produced alongside the intended frequencies by the headphones. This test differs from Total Harmonic Distortion (THD) by applying a perceptual filter to each individual harmonic before calculating the total. Higher harmonics and frequencies are given more weight.
When it matters: When clean and pure sound reproduction is desired. Harmonic distortion is relatively difficult to hear, so it should only matter to those who care about the fidelity of sound reproduction.
Score components:
