Pros
Pro Good active noise cancelling for the price
Despite being affordable, the active nose cancelling performs quite well. The feature is most effective at cancelling out high and mid frequency sound. There is good reduction of low frequency noise, though minimal levels of low-frequency noise like that of car or jet engines may still be heard.
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.
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.
