The Audio-Technica ATH-M20x are decent over-ear headphones. They have an above-average audio reproduction and a moderately comfortable and stable design. Sadly, They don't block much noise, which may affect your listening experience in loud environments or while commuting.
- Above-average sound reproduction.
- Poor isolation.
- No audio controls.
The ATH-M20x are moderately comfortable headphones with a decent build and a stable fit for casual listening sessions. Unfortunately, They will slip off your head if you use them while doing sports. They have no audio controls, and the exposed audio cables that connect to the ear cups can easily get damaged. They feel less durable than the similarly designed ATH-M40x and ATH-M50x.
The ATH-M20x have a simple and understated studio appeal that's a little bland, but will work for some. They come in an all-black color scheme and share the same design as the ATH-M30x with slight differences on the back of the ear cups. They also resemble the higher-end ATH-M50x but with a different metal frame that looks slightly cheaper.
The ATH-M20x are moderately comfortable. They don't apply too much pressure to the head, and the large ear cups fit around most listener's ears. However, the ear cups do not swivel like the ATH-M40x or ATH-M50x making these headphones feel a little stiff. They also don't have as large ear cups which could get slightly uncomfortable for some.
These headphones are not designed for use while doing sports and physical activity. They will maintain their position during casual listening sessions and won't slip off as you tilt your head. However, they will quickly fall off during high-intensity physical activity and are not ideal for use in a gym or while running and jumping. Also, the cord is not detachable and may yank the headphones off your head if it gets hooked on something.
The M20x are not portable headphones. They do not fold into a more compact format or have swiveling ear cups that lay flat. They are cumbersome to carry around and will occupy quite a bit space in a backpack and may not be able to fit comfortably in a handbag. Their cable is also a little bulky and is non-detachable, which can be frustrating when transporting these headphones. They also don't come with a case pouch.
Build quality is average. These headphones can handle a couple of drops without getting damaged and feel sufficiently dense. Unfortunately, their build quality feels cheaper and less durable than the ATH-M40x and the ATH-M50x. The metal frame used is thinner and exposes the audio cable connecting the ear cups. Unlike the higher-end models of the same design, this exposed cable makes the M20x more likely to get damaged by wear and tear.
- 100% Avg.Temp.Difference
The ATH-M20x have above-average audio reproduction and minimal harmonic distortion. They have a pretty even sound that's not too bass heavy but still packs a punch. Instruments and vocals sound slightly forward but lose a little clarity because of the dip in the high frequencies. Unfortunately, their closed-back design reduces the openness of their decent sound quality.
Good performance. There is a bit of a lack in low-bass, which affects the thump of kick drums and low-frequency effects. Conversely, bass is overemphasized by about 2dB, which adds some excess punch and warmth to the sound. However, it does not make up for the lacking low-bass.
Very good performance. The mid-range is virtually flat, but slightly overemphasized, meaning the overall sound of the headphones is slightly mid-rangy.
Decent performance. The dip surrounding 5KHz negatively affects the clarity and intelligibility of vocals/leads. The overemphasis at 8KHz and above makes the sound noticeably sibilant and airy, which may be too sharp for some.
- 100% Avg. Std. Deviation
Below average soundstage. These headphones don't activate the HRTF resonances of the outer that much, therefore the sound will be perceived to be coming from inside your head. The openness of these headphones is also below average, which hurts the soundstage even more. We also detected some out of phase crosstalk in these headphones which very slightly widens the stereo image at the expense of weakening the phantom center.
Good performance. The amount of harmonic distortion at 90dB SPL is quite good. At 100dB SPL, there is a general rise in harmonic distortion while remaining within good limits.
These headphones only provide passive isolation. This means they don't actively block or cancel the noise that seeps into the ear cups. Sadly, this is not enough for loud environments like on a train or plane, and is not ideal for commuting. They also leak at higher volumes, and may be distracting to the people around you when used in an office.
Poor isolation. These headphones don't have active noise cancelling, and the passive isolation provided by the ear cups is average. They provide no isolation in the bass region and only start to kick in at around 300Hz. The total amount of isolation provided in the mid-range is about 10dB which is below average. In the treble range, the overall amount of isolation is about 27dB which is decent.
Decent leakage. The majority of the leakage is happening between 500Hz and 3KHz, which is relatively broad. This means that the content of the leakage (lyrics for example) may be intelligible to the people around you at moderate to loud volumes.
