Your studio experience is enhanced with superior sound isolation and swiveling earcups for convenient one-ear monitoring. Engineered with pro-grade materials and robust construction, the M40x excels in professional studio tracking and mixing, as well as DJ monitoring.

Comments about Audio-Technica ATH-M40x Closed-Back Professional Studio Monitor Headphones:

Here is my honest review for these headphones.

The two detachable cables are a very nice feature. I do, however, wish that they also came with a third short cable like the ATH-M50x. The cables feature a proprietary "twisting" locking mechanism so that they cannot accidentally be unplugged from the headphones. Both cables have a 3.5mm plug, and the headphones come with a 1/4" adapter which can screw onto either detachable cable.
The headphones are made out of thick hard plastic. They are not insanely durable, but they are durable enough that I would not be able to break them unless I intentionally used excessive force. With proper care, these should last forever. The two detachable cables are also very durable.
Comparing to the ATH-M50x, these are lighter and fit more snugly. If you have a small head (as I do), you should certainly consider this. The ATH-M50x's actually fell off my head quite easily. This is not the case for the ATH-M40x.
The headphones fold into a compact design and fit snugly into the provided carrying bag.

The ear pads are extremely comfortable. I have worn these headphones at my job for 8 hours straight with no problems except occasionally having my ears get warm. This isn't really an issue because an occasional trip to the bathroom will give your ears a minute to cool which is all it needs.

Sound isolation is not great, as these are not designed to be noise-canceling headphones. However, they do contain the sound in your ears quite well. I've listened to these headphones at my job, which is a pretty quiet office environment. I can listen to these fairly loudly while having the person sitting at the desk next to me not notice at all.

This is really where these shine. The sound quality is amazing, and if a flat frequency response is what you are seeking, look no further. You simply cannot find another pair of headphones in this price range with this sound quality.
Comparing them to the ATH-M50x, I actually prefer the ATH-M40x. The ATH-M50x ever so slightly emphasizes the lower frequencies. Again if you're looking more for a flat frequency response (as I was), the ATH-M40x are a better choice. (Plus, they are almost half the price.)

I cannot recommend these enough. I know this is cliched, but you actually do hear things that you never noticed before when listening to these headphones.
I use these for mixing (and I know, technically closed-back headphones should not be used for mixing), but I am on a budget and these headphones have proven to be invaluable.
The value of these headphones is really amazing. They are easily worth double their price.
These are not very flashy headphones. Available only in black and with a very plain design, they are a "strictly business" pair of headphones which are durable, feature-packed, comfortable, and sound amazing.
