The ANC feature on the AirPods 4 has been rated as average as per some users, however, it ought to be taken into account that these are open EAR type earphones so that won’t be a trade off. The howling dampness like the biggest numbers in this class, does outperform quite a substantial diminishment of surrounding noise – around 40%-50% if compared with AirPods Pro, with the gruesome real sound full of noise eliminating Waves, unnecessary feeling, something like ripping fake barriers. It particularly has been well-enhanced to manage low-pitched frequencies of sounds such as motor noise or low bass. While the Sony WF-1000XM4 or Bose QuietComfort should be put above those levels, these are meant to be quite extraordinary that it is effective at all given the design of these earbuds.
