      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.

                  way better than beats or any other overpriced garbage headphones, quality build and audio very impressed. only problem is the extremely long cord..although i can't really complain about it because these are meant for studio use, but it would be nice to have a "normal sized" cable as an option. other than that i love them.

                        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.

                              Audio-Technica's ATH-M40X headphones are my all time favorite headphones. These are the new and improved versions of Audio-Technica's ATH-M40/FS/45 and other older M40 headphones. These are just as comfortable as the ATH-M30s but with nicer padding on the cans and bands and are mostly made with metal and plastic. These come with two cables one 9 foot one for home use and a 4 foot for portable use. These headphones have the best sound quality that can be compared to headphones costing 300 dollars or more. These headphones are flat sounding meaning that all lows, mids and highs are brought out evenly and superbly. These M40Xs bring out all the subtle details in music that most headphones can't produce. An example would be the acoustic guitar in rock bands that no one hears. These are fantastic with every genre and I love the nice studio sound they give with well done detail and separation of all the instrumentations and voices. These, even at the highest painful volumes, create no feedback or distortion. I highly recommend these to everyone who loves music.

                                  Unfortunately, there is no cable with an in-line microphone available for the ATH-M40x or ATH-M50x.

                                  If your considering purchasing a similar quality headphone that does feature a cable with an in-line microphone, then we recommend purchasing the ATH-MSR7.

                                How big are the ear cups on the m40x? (horizontally and vertically)

                                I have relatively large ears and the only headphones i can compare it too is my g430 (which fits nicely)
                                Im worried that if i order it online and it comes it wont be able to cover my entire ear (which i intend the headphone to do so)

                                Please give me the specifics of the size of the ear cups!
                                Or you can just tell me whether it will cover my entire ear from the g430 reference if you can! (much appreciated)

                                  That depends; if you want to cater to the masses then you might want some headphones with a built in bassey eq or you could just add a software eq but they work quite well for reproducing all sounds

                                  If your looking for a pair of headphones that will give you exactly what the song your making 'sounds' like, then yes these would be a great place to start since the headphones do not distort the audio with base.

                                  Make certain that the plug is being fully inserted into the headphone jack on the computer. If this does not correct the problem, contact the computer manufacturer as the problem appears to be isolated to the computer.

                                  The locking connector used at the headphone is a proprietary type connector. The model number of the cable only is HP-CC. Please contact our distributor in Canada, Erikson Audio, and see if they can help you obtain one.

                                  The carrying case is "pleather" meaning it is a plastic or synthetic representation of leather, when comparing it to actual leather there is a clear difference

                                  i'm not entirely sure if the cushions are leather or not, but i'm pretty sure that the carrying bag is a high quality poly-leather. hope this helps you with your purchasing decision.

                                  ALL Headphones sold by ATUS (Audio-Technica United States) are vegan-friendly except the following:

                                  • ATH-CKW1000ANV (leather case)
                                  • ATH-W5000 (leather earpads)
                                  • ATH-W3000ANV (leather earpads)
                                  • ATH-ESW9A (leather earpads)

                                  The non-leather material we use for the ATH-M40x headphones is made with a vinyl-based or polyurethane-based material that we refer to as “leatherette”. The carrying pouch for all M-Series headphones (including the ATH-M40x) is also vegan-friendly.

                                  However, since you are located in the United Kingdom, please direct any future questions towards the Audio-Technica division in Europe:

                                Could you release an inline (mic/control module) cable for the m40x/m50x headphones, in the future?

                                Removable cables are quite brilliant. This allows for future design changes, depending on the owner's application. I happen to have interests in both video/audio editing, as a hobby, but have many other needs. So I think it might be valuable to offer an additional 4 conductor 3.5mm cable, that includes an inline mic and audio controls for Apple's iDevices, and MacBooks.

                                  You do make a cable for the ATH-ANC9, which has inline controls. The mic is not important. But I don't see how the headphones have anything to do with what can be engineered for the cable. You have left, right and ground for the headphones, and a 4th conductor to an iPod/iPhone at the other end.

                                  Thank you for your feedback.

                                  Unfortunately, the ATH-M50x and ATH-M40x do not feature a microphone, and there is no in-line microphone cable or adapter that will work with the ATH-M50x Professional Studio Monitoring Headphones.

                                  Products you might be interested in that feature a 4-Pin TRRS Headphone/Microphone Communications connector are the ATH-ADG1 and the ATH-AG1.
