The Audio-Technica ATH-M30x are above-average-sounding headphones with a decently sturdy and comfortable design. They don't leak much and won't distract the people around you. However, they are not stable enough for gym use and won't fare as well in loud environments because they don't block much noise.

Audio-Technica ATH-M30x Design Picture

The ATH-M30x share the same understated and slightly bland design as the ATH-M20x. They're robust enough to withstand a few drops, and they're moderately comfortable. They are also stable during casual listening sessions. However, they will slip off your ears if used at the gym and their featureless design lacks audio controls and a detachable audio cable, which is slightly disappointing.

Style
Audio-Technica ATH-M30x Design Picture 2

The ATH-M30x do not change much from the ATH-M20x. They have the same design with minor changes to the back of the ear cups. They also come in an all-black color scheme and have the same understated look as the rest of the ATH-M series. However, the M30x and M20x look more cheaply made than the higher-end ATH-M40x and ATH-M50x.

Score components: Subjectively assigned
Audio-Technica ATH-M30x Stability Picture

These headphones are moderately stable and stay in place during casual listening sessions. However, they're not made for sports and don't exert much pressure on your head which makes them slip off your ears if used at the gym. They also do not have a detachable cable like the ATH-M40x and ATH-M50x and could get yanked off your head if something hooks the cable.

The ATH-M30x are decently portable headphones. They are on the larger side of over-ear headphones but unlike the ATH-M20x, they fold into a more compact format that will fit in a backpack or handbag but will be too large for most jacket pockets. The thick, non-detachable audio cable is also a bit cumbersome to carry around. They also do not come with case or pouch which is slightly disappointing.

Audio-Technica ATH-M30x Build Quality Picture

The build quality of these headphones is average at best. They can withstand a couple of drops without getting damaged, and the plastic used for their design feels dense and relatively durable. However, the metal frame used to reinforce the headband is thinner than the one utilized for the ATH-M40x or ATH-M50x. They also have exposed audio cables, which connect to the ear cups that can easily get damaged by wear and tear.

Audio-Technica ATH-M30x Frequency Response

The ATH-M30x have a good, even sound but a below average soundstage because of their closed-back design. Bass is nice and punchy and does not overpower the vocals and instruments, which are also well reproduced for the most part. However, they struggle a little with the high-frequencies, which affects the clarity of vocals and lead instruments, like guitars. They also have a bit of harmonic distortion at high volumes, which could be noticeable for some.

Poor treble. The dip surrounding 5KHz negatively affects the clarity and comprehensibility of vocals/leads. On the other hand, the sibilant sounds are slightly overemphasized, which could be a little sharp for some.

5.5 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
:
6.19 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.
Good value: >7.5
Noticeable difference: 0.5

5.3
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
:
2.7
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
:
-0.27 dB

Poor soundstage. The shallow and small earcups of these headphones don't activate the outer ear resonances enough to bring the soundstage to the front as opposed to inside your head. At the same time, these headphones are closed-back and don't sound very open either. On the positive side, our test unit drivers were very well matched.

8.2 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.

Subpar performance. The amount of harmonic distortion in bass and mid regions are quite good, even at 100dB SPL. However, there is a spike in harmonic distortion at around 5KHz, which corresponds to the dip in frequency response.

6.3

Isolation

Show Help
Score components:

These headphones only provide passive isolation. They can block some high-frequency noise with the quality of the seal the ear cups create around the ears. Unfortunately, it's not sufficient for loud environments. They will not fair well on a plane or a train unless you are listening to your audio at really high volumes. On the upside, they don't leak too much but will be audible to the people around you in a quiet office.

5.7Mixed Usage
Show Help
What it is This is the combination of the different use cases to evaluate how versatile the headphones are. Therefore an everyday headphone should be well-rounded enough to adapt to most situations and environments without significant losses in sound quality, design ergonomics or isolation.
Score components:
Mediocre overall design. They would perform adequately well as everyday headphones, but lack a decent control scheme, and the passive isolation is a little weak.
6.9Critical Listening
Show Help
What it is The level of audio fidelity a headphone can reproduce. Therefore a balanced and true representation of bass, mids, treble, soundstage and imaging, as well as a comfortable listening experience, is essential for critical listening.
Score components:
The M30X have a surprising amount of audio fidelity for their price range but have a poor soundstage because of their closed back design. They perform above-average for critical listening but may lack a little openness.
