If you have really bad tinnitus, you can use your iPhone and Airpods Pro to get some relief.
As many tinnitus sufferers like myself know, the never-ending ringing in your ears can become unbearable at times. Sometimes white noise can help by making it harder to distinguish the ringing from other sounds. I know I've run fans in my bedroom while falling asleep to help distract me, for example.
You can use the iPhone's Background Sounds feature to generate this noise for you. And with Airpods Pro, you can deliver the sound directly to a single ear and let external sounds in so you can still hear what's going on around you.
Here's how you do it.
On your iPhone, go to Settings > Accessibility > Audio/Visual > Background Sounds
Turn on Background Sounds
Select the sound you want to hear. I like balanced noise for tinnitus relief.
Insert your Airpods Pro to get them to connect to your phone.
Activate transparency mode on the Airpods Pro to let environmental sounds through.
The background sounds will play continuously, but will be suspended for announcements from Siri and phone calls. Interestingly, background sounds are just reduced in volume by about 90% when you start playing Apple Music. There's a setting in the Background Sounds pane that will disable the background noise while media is playing. Otherwise it will continue playing but will be reduced in volume. Background sounds resume normally after stopping any of those activities.
You can do that, but it's provided on iPhone without any internet connection, it integrates seamlessly with system events, there are no download or install requirements, and if you use Airpods Pro, you can mix in environmental sounds. Plus, as another user mentioned below, you can add a toggle for this setting in the control center. That's a stellar implementation!
