Pros
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.
Pro Full bass with adequate levels of mids and highs
Despite the compact size. the bass is full, has great impact, deep extension yet is not loose. The low end also has a natural quality to it that makes these headphones great for music that is performed using real instruments.
The mids are slightly recessed, but also have a natural tone. The highs are the most recessed or rolled-off, but the detail and airiness of the music is not totally absent. This quality helps give the sound a smooth and pleasing tonality.
Pro Ear cups can swivel facing outwards
The K81 can be used “DJ style”, wherein only one ear cup is in contact with the head. The cups have a smooth swivel action so they can be rotated to face outwards. A user can choose to hold one ear cup up to his or her ear while flipping switches or turning knobs on the mix board with the other hand.
Pro Easy to travel with
While these are already quite compact, the ear cups can be folded into the headband to reduce their size even further. This makes them easy to stuff inside a bag and travel with.
Pro Comfortable to wear even with extended use
The clamping force is not too much at all, so acceptable levels of pressure will be applied on the ears. Also, the ear pads are thick with ample pleather padding on the surface. This combination provides adequate cushioning between the ear cups and sides of the head.
Pro Can fit a wide range of head sizes
The aluminum headband itself has some good flex. Combined with the sliding mechanism of the ear cups, K81 can be adjusted to fit a wide range of head sizes. Also notable are the numbered steps on each side of the headband, which allow for accurate and consistent ear cup positioning.
Pro Feels high quality
Although it's mostly made of plastic, the materials don't feel cheap at all. Aside from feeling sturdy, the plastics have a smooth rubber coating which makes them feel premium to the touch. Also, the headband is made out of aluminum which is significantly more durable than an all plastic one.
Cons
Con Incompatible with cables from other brands
Only Audio Technica cables can be used with these headphones.
Con On-ear design can still be uncomfortable
While the ear pads are thick and give a lot of cushioning, some may still find this to be uncomfortable. Being on-ear, some pressure is applied onto the ears.Those who are sensitive to this may still feel some discomfort, especially when worn for several hours straight.
Con Highs may sound too recessed
People who prefer their music with sparkly highs and utmost clarity likely won't find these headphones to be a good listen.
Con Lengthy cable can be a hassle
The cable is 2.5m which is fairly long. Since it is not detachable and the cable tends to tangle quite easily, it may cause some problems with regular home use or when taking these headphones on the go.
