Pros
Pro Lightweight
Pro Fairly neutral sound signature
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.
Pro These have a high quality and durable feel
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.
Pro Can be used in noisy environments
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.
Pro Comes with two detachable cables
The headphones come with a straight cable and a coiled cable, making them useful in the studio or while walking.
Cons
Con No microphone
Con No ANC
No Active Noise Cancelling
