Audio-Technica ATH-M40x vs Audio-Technica ATH-M50x

Sound signature is quite accurate, almost flat. Bass is much more controlled instead of boomy, while there is a slight elevation on the highs, resulting in extra energy and detail up top. These offer a nice middle ground between a fun sound and a more reference/analytical sound signature. This sound quality makes the headphones quite versatile as music enjoyment headphones or studio-use cans.

The M40xs feel solid and are known to be quite durable. The plastics used in the build do not easily flex or make creaks, giving the impression that these can last quite a long time.

The over-ear, closed back design along with the thick pleather ear pads can block out quite a lot of ambient noise, and will help users to focus in on the music. These make the headphones great for travel or for mixing/monitoring use.

The headphones come with a straight cable and a coiled cable, making them useful in the studio or while walking.

The ATH-M50x are great sounding headphones with a sound that may fall in the neutral category, but with very slight boosts to the bass and highs; a slightly V-shaped sound. The bass is full and has a lot of power. The sub bass has a hint of elevation though, which can make the bass sound a bit loose on hip-hop or EDM tracks. The mids are fairly neutral with no elevation. The highs are also slightly elevated, which does not add harshness but instead gives the sound a shimmery and detailed feel.

This sound signature of the M50x makes it versatile. It is neutral enough for monitoring use, yet also has just the right qualities to make it a great choice for enjoying music.

The bass of these headphones sound full with a slight boost. This makes the bass quite punchy without drowning the mids or highs.

You get a lot from what you pay for with these headphones. Aside from the great sound, they are also well built and come with a lot of accessories.

The ATH M50x is made from high quality matte plastics which are quite resistant to damage without being too heavy. The hinges move smoothly and do not have unnecessary creaks.

Audio-Technica finally updated the M50's built in cable to a detachable cable. The M50x even comes with three cables, a 1.2 m - 3.0 m coiled cable, a 3.0 m straight cable, and a 1.2 m straight cable. None of the cables have in-line controls though.

The ear cups and pads are able to keep the sound in and block outside noise. These are suitable for a noisy office as even low volume music is enough to drown out those noisy office mates.

The ear cups can be folded into the headband, reducing its footprint. Combined with the carrying pouch and detachable cables, you can easily chuck these headphones into your bag when going out.
