When to Call a Professional

If ANC still does not work after completing all steps above, especially if it fails on multiple devices, one or both ANC microphones may be physically damaged or defective. In this case, contact Apple Support at support.apple.com or visit an Apple Store or Apple Authorized Service Provider. If your AirPods Pro are within the one-year limited warranty or covered by AppleCare+, Apple may replace them at no charge. Apple also issued a free service program for ANC issues on certain AirPods Pro models manufactured before October 2020 — check Apple's official service program page to see if your device qualifies.

Frequently Asked Questions

Why did my AirPods Pro ANC suddenly stop working?
The most common causes are a software or firmware glitch, a poor ear tip seal, blocked microphone ports from earwax or debris, or a Bluetooth pairing issue with your device. Less commonly, a hardware fault in the ANC microphones can be the cause, especially on older AirPods Pro units.
Does Apple have a free repair program for AirPods Pro ANC issues?
Yes. Apple launched a free service program for AirPods Pro units manufactured before October 2020 that experience sound issues including ANC problems. Visit Apple's official AirPods Pro Service Program page and enter your serial number to check eligibility.
How do I know if my AirPods Pro firmware is up to date?
Go to Settings > Bluetooth on your iPhone, tap the ⓘ icon next to your AirPods Pro, and scroll down to 'Firmware Version.' You can compare this number to the latest firmware version listed on Apple's support website. Firmware updates happen automatically when the AirPods are in their case, connected to power, and near a paired iPhone with Wi-Fi enabled.
Will resetting my AirPods Pro fix the ANC not working issue?
A factory reset often resolves ANC issues caused by software corruption or a bad Bluetooth pairing state. It clears all stored settings and forces a fresh connection. However, if the problem is caused by physically damaged microphones, a reset will not fix it and Apple service will be required.
Can a dirty ear tip cause ANC to stop working on AirPods Pro?
Yes. ANC relies on small external and internal microphones to sample and cancel ambient sound. If earwax, dirt, or debris blocks these microphone ports, the ANC system cannot function properly. Regular cleaning of the ear tips and microphone grilles can prevent and resolve this issue.
