    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 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.

                  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.

                      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!

                          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.

                            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.
