    I'm a Producer/Songwriter from Chicago, IL and I could've spent hundreds of dollars on a pair of any competing set of studio headphones but I took a chance on Audio-Technica because I love your condenser microphones. So when I ended up purchasing the ATH-M40x, I knew they were part of the latest series but didn't expect much in lesser price range.....I ate those words immediately after I took a listen to some of my favorite songs as well as my own mixes. I love the fact that I can be so confident in such a reasonably priced pair of headphones for general listening as well as tracking and mixing to the point where i'm making people that don't make music at all go buy a pair as soon as they hear mine. The 40mm drivers are EVERYTHING, amazing flat response, simplistic design & the included leather carrying bag has been such a big help. I went through a short period where I was creating and mixing tracks with no monitors and all I had was a cheap interface and the ATH-M40x's. As it turns out, when I play my mixes for actual engineers, they're incredibly impressed and always say things like "you know, it sounds perfectly fine just the way it is". These have been my life-line and will continue to be a part of my mobile setup. I will eventually get a pair of M70x's however, I will always keep these at bay just in case. Thank you Audio-Technica and continue to make dope products.

    It's a really great product. It's a bit pricey in my country but it was worth it. The sound is very accurate. I would not call myself an audiophile but the sound is really great. My only problem was that the hinge got broken but I got it repaired from a 3rd party service who just used some soldering iron. The ath-m40x was my first good pair since I'm only 13.

    I use the ATH-M40x mostly for music and youtube and it works great for both. I can sometimes be scared to use it because of the folding mechanism.

      Comments about Audio-Technica ATH-M40x Professional Monitor Headphones:

      I bought these headphones for use as a DJ to replace my old pair from another company. I've been using them for just over a week and decided it's time for a review. I'm impressed with the build quality. My old pair of headphones are a little larger than these so to me these are fairly compact and sleek for over ear headphones. The headband is metal and maybe a little stiff giving a firm clamp force that was a little achy to wear at first but now I don't notice it. The headband and ear pads are soft and cushy but feel durable. I don't anticipate the material to flake off like my old headphones. The ear cups and the yokes connecting them to the headband are plastic. The yokes may be an issue, only time will tell.

      I'm sorry to say there are two things I don't like about these headphones. First, I'm not a fan of swiveling ear cups. It's nice that you can hang the headphones around your neck with the cups swiveled out away from your chin but putting them back on your head can be difficult because they can fold into weird positions if you're not careful. Second, the sound quality is lacking in detail/treble. These are my first pair of "flat" headphones. The bass and mid range are well represented but the high frequency is subdued. As a result the sound is muddy, lacking detail. This can be corrected with a graphic EQ program on my laptop but not on most stand alone devices like my DJ mixer.

      These are OK and I can make use of them but I'm continuing my search for headphones more suited to my needs.

          Comments about Audio-Technica ATH-M40x Professional Monitor Headphones:

          I use these headphones to mix all of my music before going into studio to final mix, they are incredibly reliable and have found no faults in the quality. I have compared these to the more expensive ATH-M50X model, and for almost half the price the ATH-M40X headphones take the upper hand due to their Flat Frequancy response that the M50X's don't have!

              Comments about Audio-Technica ATH-M40x Professional Monitor Headphones:

              I bought these to replace my 4 year old m50, which had a broken hinge. The m40x is a good replacement and is actually lighter and more comfortable than the m50 in warm environments. It comes with two cables, one coiled and the other straight, and this was a huge upgrade from my old m50's as the straight cable non-detachable cable was prone to tangling. I am not an audiophile but a casual listener, but in my opinion, the sound is just as crisp and flat as the m50. There is some sound leakage, but it is expected for a headphone at this price range and it was not advertised as such. I would definitely recommend these for the casual listener.

                I loved these headphones with all my soul but the rotation of the cups are a little weird. Mine recently broke when the right cup got stuck and i was the plastic holding it together broke off. I could not believe it because i barely put any force into it. if you pick these up and rotate the cups the wrong way they can break off fairly easily. Im in the process of claiming my warranty but even tho i love the M40x im scared of the fragile design. Im most likely gonna trade my new pair in or sell them to work for a pair of M50x or M70x.

                        i am a music teacher and DJ. I use these phones for when I record my students, run sound for concerts, and occasionally when I do dances. First off....the sound quality is unbeatable!! Very true flat phones. I have cranked the volume very loud with no distortion and you are able to hear everything! The padding on the cups get a little warm but nothing that can't be ignored. The isolation is great....and did I mention the sound quality! Unbeatable in a headphone at this cost!!! the plastic makes me a little nervous, but it hasn't broke yet (after 9 months of wearing ALOT)

                          As a college student i routinely listen to music, play video games on my computer, and audio edit videos. From the 100+ hours of using this product i can say without a shadow of a doubt that these headphones are worth every penny they cost! These headphones have gone head-to-head with other headphones, costing several times more, and have stood their ground. The only drawback i can think of would be that the headphones will occasionally pick up a small buzzing sound from the impedance of your computer system, which can easily be fixed by a digital-to-analog converter.

As it turns out, when I play my mixes for actual engineers, they're incredibly impressed and always say things like "you know, it sounds perfectly fine just the way it is". These have been my life-line and will continue to be a part of my mobile setup. I will eventually get a pair of M70x's however, I will always keep these at bay just in case. Thank you Audio-Technica and continue to make dope products.

                                Thank you for your inquiry. Check and make sure the cable is pushed all the way in to the ear cup of the headphone and turned into the locking position. Sometimes these can get pulled slightly out over time causing you to only hear one side of audio because the connector is not fully seated into the headphone.

                                If you are convinced that the issue is with your M40x's, you will have two options:
                                1. Exchange/return the product to the dealer from whom you purchased, pending their policy.

                              I currently have the ath-m40fs headphones and was thinking of upgrading to the ath-m40x but the specs listed for frequency response for my old (discontinued) m40fs are much better than the m40x (m40fs: 5 - 28,000 hz vs. M40x: 15 - 24,000 hz). How is the new model better than the old one? Isn't it all about sound and isn't sound all about the widest frequency response? I'm confused. Thank you. Jeff R.

                                Thank you for your inquiry. Considering that the common range of human hearing is from 20-20,000 hz, there is no need to be concerned about the "narrowing" of the frequency response on the M40x's as compared to the M40fs's. Like the M40fs's, the M40x's still offer the most flat frequency response out of our M-Series Headphones. The M40x's also have the capability to fold into a more compact position for easy storage, the cable has an 1/8" end to plug into standard headphone jacks and comes with a 1/4" adapter, the cable can be removed/replaced in case the cable is accidentally damaged one will only need to replace the cable and not the whole headset. So it has a few more features to it compared to the M40fs's but still the same, if not better audio quality.

                              What is the little dot on one side supposed to mean? ¿Is the connector side suppossed to be in the right ear? If is like this I have several balance issues because the in the right cup sounds the left channel and in the left cup the right channel. I have tried with different devices (Mac, Android) and the problem remains.

                                Thank you for your inquiry. The cup with the dot on the side and the cable coming out is the left side. This cup goes over your left ear. The side with no dot and no cable goes over you're right ear. There are a big "L" and an "R" on the inside of your headphones on the plastic part to indicate which side is which. Yes that is why you are having balance issues. Notice that there is not only a dot on the headphone cup, but also at the end of the cable coming out of it. when these two dots are lined up this indicates that the removable cable is locked into place. You can turn the cable to the left and remove it from the headphones.

                                Sometimes if the connectors are not making the proper connection to your source, that can cause a disturbance in the sound. This can come in the form of low volume on one side, static sound, etc. If manipulating your cable did make the sound correct, then we know the headphones are in working order. Also, if you have a case on your source, that can sometimes cause the cable to not properly seed. You will also want to check and make sure the locking end of the detachable cable in the headphones is fully locked in place.

                                If you are convinced that the issue is with your headphones,then you will have two options:
                                1. You may exchange/return the product to the dealer from whom you purchased, pending their policy.
