    Best Value Professional Headphones.


    I like the Sound and Style of these Headphones.

    Houston. Texas.




    I use these headphones for gaming on my pc, iv had them for 2 years and they are amazing, I haven't found a flaw in them yet. The are comfortable, don't take too much space, not easily breakable( like some of my last headphone were), they are overall awesome



    Great headphones for price.


    The ATH-M20x's are great value for performance over-ear headphones. They have a great neutral sound. Furthermore, I can wear them for 3+ hours without them feeling uncomfortable. Also, they sport a high quality cable and jack that has not failed or faltered for over 2 1/2 years of continuous use. They do have their down sides though. One being that in practice, the cord is usually to long. And when ran through an amp they sometimes cant get as loud as my drums or they distort low frequencies at loud volumes. The latter complaint is probably due to its decibel limitations. On a final note I would recommend this product to people who need a great sound on a budget.

    Long Term Reliability


    I've used these headphones in-studio for voiceover and mixing since approximately 2004. For the price, they have provided excellent service. For any product these days, 13 years a long run. One of the best features has been the lack of tension pressure. It is something I feel is an important consideration, particularly when you have to wear them for extended periods of time. I have a pair of noise-cancelling Bose headphones for travel, and after an hour, it feels like I've be in a vacuum with a vice on my head. That's not the case with the M20s. I sometimes wear them for hours (while writing in the studio) without even realizing I am still wearing them. While it is time to replace them, I'm confident I'll stick with Audio-Technica.

    Worthy junior to the ATH-M'X0' Lineup


    This was my work earphone which I generally use while at the desk, its not heavy on the head but its not that convenient for travelling. The Sound Quality is great for this price and the padding helps to block most of the outside noise. The 47 Ohm impedance requires a good playback device for the crystal clear sound but it generally worked with all the devices I tried. The sound stage is quite wide for a closed back headphone and its clear in its entire range. The frequency response is mostly flat with slight bass emphasis but doesn't overdo it!



    I love it,its amazing for the price


    Its so minnimal and strong on the looks,and its perfect in the audio performance.i like it,it has nothing too flashy,its just focused on performance and quality



    Affordable, high quality headphones


    I use these headphones when walking to work and at the office. At home I have a 6 year-old pair of ATH-M40fs, which still sound amazing. The listening experience is very pleasurable. I hate "mega bass boost x-treme" coloration in the sound, therefore the ATH-Mxx series has been my go-to headphone for personal use and my main recommendation for aspiring audio enthusiasts. Any genre of music sounds great with these. I listen to a plethora of musical genres - from extreme metal to folk. Regardless of the genre, any well-mixed/recorded album will sound great. I have yet to use them in a recording context, but comparing them to my ATH-M40fs, they should fit in just right. Slightly more pronounced low frequencies, but not too much. At home I use them with an external headphone amp and at work/walking to work, from a computer sound card or my phone jack. It doesn't lack power with regular devices and with my amp it can handle very high volumes while maintaining clarity. Ergonomically, I wish I had gone for the m40x headphones, since the additional swivel and detachable cable are a value that you don't account for until you see it's value. Due to the long cable, i have to bunch the cable together when walking. Otherwise, great headphones for a great price.

    you can buy this product under $50


    it is very good to use , but its ear buds are getting heat for long use, bass lovers kindly avoid it , u can get reasonable bass and good mid sounds and awsome high freq sounds other than that it has good design for this price, don't compare with rest of the m-series headsets ,it has also a affordable price ,headbands are made up of some good material. finally it is very cool and mainly for professional monitering purpose first understand that and buy if u have professional use or else u can go for any other audiotechnica models

  • Q & A

    Do brainwavz hm5 earpads fit on m20x?


    You may contact your local Audio-Technica offices for further assistance.


    Will these work with a Mac and does it include a 3.5mm jack to plug into a phone or computer?


    You may connect to 3.5mm or 6.2mm headphone connections.


    Is it compatible with Lenovo k5 note


    You may connect the ATH-M20x headphones to any standard 3.5mm or 6.3mm headphone output connection.


    What is the difference between the M20x and the M30x? They appear to have the same specs.


    Each set of headphones will have their own sonic signature, which is subjective. Additionally, as you "go up the food chain," you add additional features which can be objective. The ATH-M20x headphone earcups swivel 15 degrees in both directions and the ATH-M30x headphones are the same but also fold up for storage.


    Is the cable removable?


    Thank you for your inquiry. No, the cable is attached.


    Do I need to use the headphone with an amp or not?


    Thank you for your inquiry. One is not necessary.


    How long exactly is the cable in Feet?

    Austin Worden

    Thank you for your inquiry. The cable is approx 9.8 ft long.


    Is there a mic inline for answering phone calls


    The M Series headphones including the ATH-M20x headphones, being designed for professional studio monitoring, will not have consumer headphone features such as an inline microphone and controls available. You may use a third party inline microphone to use with your headphones.


    so I see this does not have a volume control ( very disappointed ) but I saw an answer to add a third party volume controller, can you tell me where to get that? thank you


    Yes, you may use any third party inline volume control. You may contact your local electronics store to inquire of their stock of inline volume controllers that may best suit your needs.


    There is a set volume coming through the earphones. Is there a way to control the volume. I turn the volume down on the tv, but the sound does not change.


    The volume attenuation is done by the source providing the audio to the headphones. You may use a third party inline volume attenuator.
