Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Balanced and clear sound
These headphones will sound great with a practically all genres of music. The highs are slightly rolled-off, but still present a good level of detail, so these headphones are not harsh. The mids are warm, while the bass is controlled instead of boomy.
Pro Extensive accessory bundle
The ATH-ANC23 offers good value for money due to the extras that you get. The accessory pack includes a carrying pouch, the active noise cancelling in-line control hub, an alkaline battery, an airplane adapter and a number of eartips, including foam ones, which provide a better seal and noise isolation than the standard silicone tips.
Pro Good active noise cancelling
The active noise canceling feature blocks out high and mid frequency noise quite well. Voices and environmental noise aren’t likely to interfere with your music. Loud, low-frequency noises like jet engines may still seep through though, so these are not the best for long flights.
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 The control unit to earpiece cable may be too short
If you are a tall person, you may have a problem positioning the large active noise cancelling module. The wire connecting the module to the earpieces is quite short. This can make it a little difficult to clip the module to your belt or pocket, which can get annoying.
Con Noise cancelling is not very effective on low-frequency noise
You may still clearly hear low-frequency noise, even with active noise cancelling turned on. The feature is effective on high and mid frequency noise, but not that well on low-frequency sounds. Loud engine noises may still mix in with your music.
Con Incompatible with cables from other brands
Only Audio Technica cables can be used with these headphones.
