Ear Assist vs Basic Detection

Ear Assist turns your iPhone or iPad and a pair of headphones into a sound amplifier. It picks up sound through the microphone and plays it louder in your ears, so you can follow the lecture from the back row, keep the TV at a volume that suits you, or catch the conversation at a busy table. LOUDER WHEN YOU NEED IT • Volume control plus Boost: add +6, +12 or +18 dB with headphones • Boost is switched off on the loudspeaker, where it would cause a feedback howl, and limited on the earpiece • The Boost button always shows the gain that is actually applied TWO WAYS TO LISTEN • Natural: the sound as the microphone picks it up. Best for music, birdsong and the atmosphere of a room • Speech: uses Apple's voice processing to reduce background noise and echo. Best for conversation, meetings, lectures and TV SHAPE THE SOUND • Five-band equaliser from 60 Hz to 14 kHz • Lift the upper bands to bring voices forward, or cut low rumble • Save settings for different places and load them again later YOUR HEADPHONES, YOUR MICROPHONE • Works with wired headphones, AirPods and other Bluetooth headphones • With Bluetooth headphones, Ear Assist uses your iPhone's microphone and keeps full stereo sound, unless you choose the headset microphone • On iOS 26, choose your microphone from the system input menu. Your choice is remembered RECORD LECTURES AND TALKS • Record what you are listening to, saved on your device as M4A files • Recording starts only when you tap Record, and stops when you tap Stop • Please ask permission before recording other people ABOUT DELAY Listening live through headphones always involves a short delay between the microphone and your ears. It is shortest with wired headphones. Bluetooth headphones add more, and if you can also hear the sound directly you may notice a slight echo. Where delay matters, use wired headphones. GOOD FOR • Lectures, talks and the back of a hall • Meetings and busy restaurants • TV at your own volume without disturbing others • Theatre, places of worship and events from far seats • Birdwatching and nature recording PRIVACY Audio is processed on your device.
