However, due to the regulatory approval process, some countries, including the U.K., missed out on certain features, including the ability to use the AirPods Pro as a hearing aid.

To start the hearing test, make sure your AirPods are charged enough and you're in a quiet room. Once connected with a paired iPhone/iPad, head over to Settings > your AirPods. You can also start the Hearing Test from the Health app by tapping 'Take a Hearing Test' and following on-screen instructions.

The best noise-cancelling wireless earbuds in the Apple lineup are nearly back to their holiday-sale lowest price.

These under-$200 AirPods Pro 2 have a USB-C charger, they’re mag-safe, and you’ll get about six hours of battery life from the earbuds and 30 from the case. Best of all, the case has Apple’s U1 chip, so you can track it like an AirTag.

The Hearing Test can identify if you have hearing loss and can show your hearing ability at different frequencies of sound measured in decibels hearing level (dBHL).
