Build & Design

To step down the price for consumer sake, and previous models, Audio-Technica had to manipulate the ATH-M40x, making it more dynamic in variety. Moreover, the headphones boast a matte black finish with silvery gray highlights indicating the company’s the logo. Their size is indeed large, courtesy of the 40 mm audio drivers and one would think its sacrificing comfort, however, this is not the case, the earpads are made up of microfiber to provide exceptional comfort, even after long listening periods.

The earcups are heat resistant as well and rotate freely, however, some may find its flexibility undesirable.

Audio-Technica ATH-M40x Monitor Headphones


Since the ATH-M40x were built with Sound monitoring in mind, it lacks the most common Bluetooth connectivity, mic and remote accessibility features shared by other models or headphones in its class. The M-Series ATH-M40x studio monitoring headphones were designed for one thing: listening to music. Audio-Technica has provided information on how to exactly to do it, a standard cable and one remote cable. Quite an old-school way to go about it, but this high precision connectivity options supplied via two connection leads offer better quality sound from sources with balanced outputs like amplifiers.

Additionally, while the cables are 3.5 mm jacks, the ATH-M40x use a proprietary locking connector at the ends to prevent the cable from ripping out in case of an accident. However, this feature also makes it hard to replace a snagged cable, luckily, this less likely to happen, since the coiled cable has some “give”.

Audio Quality

One of the huge differences between the ATH-M40x and its more pricey brother, ATH-M40x is the driver size. The 40 mm audio drivers may be smaller in size, but they do offer decent audio experience, although not ideal for the audiophile. The small size of the drivers affects the sonic signature.

Obviously, the ATH-M40x may not be as exceptional as their predecessor, it is, however, still impressive how close these do get, and has managed to step outside of its big brother shadow. If you’re simply looking for a decent pair of headphones for sound monitoring or just for listening to music and are on a tight budget, then the Audio-Technica ATH-M40x is an amazing deal at it's current price.
