Apple has one hardware-specific feature planned that wasn’t announced at Monday’s WWDC keynote. In iOS 12, users will be able to use Live Listen, a special feature previously reserved for hearing aids certified through Apple’s Made for iPhone hearing aid program, with their AirPods.
After enabling the feature in the iPhone’s settings, users will be able to use their phones effectively as a directional mic. This means you can have AirPods in at a noisy restaurant with your iPhone on the table, for example, and the voice of whomever is speaking will be routed to your AirPods.
Live Listen is a feature Apple developed and eventually launched in 2014 that allows iPhone users with hearing aids to hear people in noisy environments or from across a room, such as a crowded restaurant or lecture hall. If a compatible hearing aid is paired to a user’s phone, there are options to turn Live Listen on and off, adjust volume and even set it as their preferred Accessibility Shortcut.
Live Listen support in AirPods is key. The inclusion of this feature makes AirPods more capable and more alluring; it’s significant given they are almost universally hailed as one of Apple’s best products in years. Soon, anyone — particularly someone with limited hearing — will have access to this feature without needing to buy dedicated hardware to get it.
Still, it’s critical to note AirPods with Live Listen is not a full replacement for a hearing aid. It’s obviously best to speak with your audiologist to determine the best solution for your ears.
