    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 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 know it is a monitoring headphone, but could have used a separate cable (HP-SC) with mic. That would have made it a prefect utility.

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

          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.

                          To be fair I just got a pair yesterday. They sound great but the only thing I can stand so far is they are very FLOPPY. Its like rearranging a rubix cube every time I take them off and put um back on. They want to collapse and the ear cup flip inside out and its annoying. There should be added resistance to how they flip around or at least an adjustable knob so they dont flip flop.

                            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.

                                The ATH-M40x headphones include the HP-CC (coiled cable) and the HP-LC (long cable.) The HP-SC (short cable) is not included but may be purchased separately and used with the ATH-M40x headphones.

                              I love these headphones, but plastic housing...connecting from the flat metal overhead strap, have cracked.
                              The Crack runs parallel just above the screws on the inside.
                              one side totally and other side getting that way quickly.
                              What part number do I need to get?
