CustomTune Technology—Sound and Silence Tailored to You

When the earbuds are placed in your ear, a chime is played. The microphone inside the earbud measures the sound in your ear canal and adjusts it to create a perfectly balanced sound for you.
CustomTune technology compensates for the differences in individual ears, as many people's left and right ears are not identical in shape, size, and condition. The result is truly personalized sound balance.
CustomTune also helps by personalizing noise cancellation to the shape of your ears. This may soften unwanted sounds that are hardest to reduce, like voices.
