    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.

    I would give these a 5 star rating if they didn't break from a flawed design and became useless. They do have great sound for their inexpensive price. But . . . where the ear pieces swivel, the plastic has way too much stress on it (poor engineering) and will crack and break off in time, rendering them useless. With mine, one side broke off completely and the other side is cracked in the same identical spot. If I could still use them, it too would break off soon. How long were they cracked before one of them broke off, I don't know, as I never suspected them to do so and wasn't checking for cracks in the plastic. If I had seen the cracks before the one side broke off, there isn't anything I could have done to prevent it anyway. I never dropped them, nor abused them, and always hung them on a hook to protect them, as I really loved them until they broke. Audio Technica's Customer service was very quick to respond to my request to buy the broken parts, but wanted me to ship them to them for repair. With MY cost for 'return' shipping, plus their repair cost, I might as well go for a new pair and keep the broken one for spare parts. That said, I would not buy these again however, as I would not want to go through the disappointment again of the plastic breaking into two pieces. If I didn't use them much, they might have lasted forever, but as I use them on a daily basis in the studio, it was just a matter of time before the plastic cracks, breaks off, and they no longer can be used. A perfect example of "a chain being only as strong as its weakest link". Audio Technica will kindly offer to repair them, though spending the time to fix the poor engineering might be time better spent. As I really liked them before they broke, I had recommended them to several of my sound engineering buddies as a good inexpensive investment. Hopefully they didn't buy them, as I don't want to be responsible when their's eventually snap into two pieces like mine sadly did.

      I've already sent this product back for repair twice and I think I broke it for the third time. Normal usage, never dropped it, still damaged in the same spot. The overall shipping cost almost reached the value of the headphone: I'm done.

          I've had these headphones for about a year and a half. I use them daily for several hours at a time, but I tend to leave them at the office and don't travel with them often so the potential of them breaking is probably lessened than most users. Regardless though, they're incredibly comfortable and have really great clarity. I'd strongly recommend them to anybody looking for decent headphones who doesn't want to break the bank.

              Sound fidelity is good to great, but the headphone body is just poor in every aspect, a complicated folding mechanism flawed and poorly thought, very low reliability and durability in plastic parts and false leather, after a few months of use it just looks like a filthy rag covering your ears, shameful and in poor taste.

                    They have no competition in their price range if sound is what you are looking for, but for me it is very annoying I cannot use them with 1 hand, something always clicks and closes. I think if they had only the 90° swiveling without collapsible ear-pads they had a stronger build, maybe had been cheaper and could have been used with one hand. I consider the collapsing feature rather a design flaw than a benefit considering I travel like 1000 times less then I put them on and off my head.

                            I loved the sound of these headphones in store, but they are so uncomfortable that I have given up using them. I have tried to stretch them out by stretching the ear cups over a box and leaving them for five days, but they are still so tight that they literally induce salivation in my mouth. I have a small head. For $160 (what I paid for them in store) they are completely not worth any of the money. I cannot use these headphones anymore and I will not purchase anything from Audio Technica going forward. Very sad, the sound quality is phenomenal and I had looked forward to using them.

                                      The M Series headphones including the ATH-M40x headphones, being designed for professional studio monitoring, will not have consumer headphone features such as Bluetooth available.

                                      The Audio-Technica ATH-M40x Headphones are not made with any animal byproducts; the earpads are not leather. The earpads we use are made with a vinyl-based or polyurethane-based material that we refer to as leatherette. Please note that we no longer use protein leather in any of our products. This was a company wide directive issued by Headquarters Quality Assurance Department in 2010.

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

                                      ATH-W5000 (leather earpads)
                                      ATH-ESW9A(leather earpads/headband)
                                      ATH-ESW990H (leather earpads/headband)
