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 Dark sounding headphones with powerful bass, full mids and slightly recessed highs
The hallmark of the LCD-4's sound signature is the bass. The lower frequencies go quite deep and also have a lot of power. This sound is achieved without bloat or muddiness. Those who prefer powerful yet still fairly accurate bass will definitely love these.
The mids are full, clear and are quite forward as well so detail from vocals or guitars can easily be appreciated.
The highs take a bit of a back seat. While there is still a good level of detail and resolution on the sound, the highs are not as sparkly or airy as other high end headphones. This can be a good thing for some though as this gives the LCD-4 a smoother sound but with less shimmer up top.
Pro Superb build quality
The build is a mix of metal, wood, authentic leather as well as carbon fiber. You can really tell that these headphones are expensive and are built really well.
Pro Soundstage has good width
The open back design gives these headphones good soundstage. Though not the widest, there is a good sense of space and separation to the sound.
Pro Heavy duty detachable cable with solid connectors
The LCD-4's cable is quite thick and hefty which should make it more resistant to breakage and other problems that most thinner cables have. Also, it uses mini XLR connectors which are much more secure as they lock in place.
Pro Ear cups feel really soft and smooth on the skin
It uses authentic leather on the earcups' surface which feel really smooth and supple on the skin. There is also a lot of cushioning thanks to the high quality foam material that is inside the cups. The foam also has acoustic properties that help seal in the sound really well.
Pro Includes a large, hard plastic shell case
The LCD 4 comes with case with ample room and padding inside for the headphones and the cable. While the case will most likely not fit in your travel bag, it will provide plenty of protection to your headphones should you decide to take them out of your home.
Cons
Con Incompatible with cables from other brands
Only Audio Technica cables can be used with these headphones.
Con Very heavy
It weighs around 700 g, and that's without the cable. This makes the LCD-4 one of the heaviest headphones in the market today and will most certainly put quite a strain on your head and neck if you decide to wear these continuously.
Con Leather material on ear cups trap heat
The leather material prevents heat from escaping effectively. This results in heat building up rather quickly around the ears when using the LCD-4, so it's likely that you'll feel uncomfortable after long listening sessions.
Con Requires a powerful amp for optimal volume and sound
Plugging these directly to your computer or smartphone will lead to poor sound, since it requires a powerful amp to get good volume and to output the optimal sound quality that they are capable of producing.
Con Leak a lot of sound
The metal grills on the sides of the earcups do next to nothing to keep the sound within the ear cups. Other people near you will most likely hear what you are listening to.
