    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.

    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.

        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 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.

                          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.

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

                          I am a very experienced headphone user of many years. Currently I own a few sets of very expensive headphones and a nice home headphone amplifier. I will admit that I purchased the M40x not expecting to be very impressed. Well I am extremely impressed.

                          The headphone is comfortable and the overall sound signature is slightly warm and balanced with very well extended, but non-sibilant or fatiguing treble. The sub-bass isn't that pronounced, but it is certainly adequate and the emphasized mid-bass gives the music an engaging quality.

                          The M40x does a commendable job with instrument separation and detail retrieval. I also find the bass response fast, but there is enough decay that the notes last long enough to sound natural. I listen to a great variety of music with an emphasis on well recorded material, but even with hot mastered rock and pop the M40x felt poised and articulate; far more so than I expected and in my mind, more than a reasonably priced headphone should.

                          You certainly could drive it well enough with the output from a phone or a DAP, but it scales very well and benefits from adequate amplification. When I drove the M40x from my home system which has a very good DAC and amp I was very impressed with the performance finding the sound signature very good even when compared against my considerably more expensive orthodynamic headphones.

                              You may plug the standard 3.5mm connection from the headphones into any standard 3.5mm headphone output connection.

                            My question could have been answered if this question was actually answered.

                            Q: Will the short cable on the m50x work on the m40x and if they do can you buy the short cable in the m50x alone.
                            A: The short cable with the ATH-M40x is the same cable as the ATH-M50x. You can also purchase the cable separately: model HP-SC.

                            The specs give cable lengths of 9.8 ft for both cables that come with the M40X. I would like a shorter cable and I think the person who asked the question first wanted a shorter cable. So what lengths are the 2 cables that come with the M40X?

                          • Q:

                            I've had these for 2 days and use them as my electronic drumkit headphones.

                            When I give the the bass drum and the hi-hat a good hit at the same time there is a really noticeable crackle in the left ear.

                            Will this go away with them getting broken in over time?

                              Please make certain you are not clipping your inputs or outputs, as this is by-far the number one reason for getting a crackle in any headphones, and is not unique to Audio-Technica product.

                              If the headphones are working properly with one device, then the issue is not within the headphones but within the connection of the second device.
