Try Immersive Audio
A must-have feature for any true music lover, Immersive Audio spatializes what you’re hearing by taking it out of your head and beyond your earbuds to create a spacious, natural listening experience the way the artist intended. Welcome to the acoustic sweet spot.

World-class noise cancellation
To deliver our best in-ear noise cancellation, QC Ultra Earbuds utilize both active and passive noise reduction technologies, employing a sophisticated proprietary approach for Active Noise Cancelling (ANC).

CustomTune technology for sound tailored to you
Proprietary Bose CustomTune technology takes your listening experience to another level by analyzing your ears and automatically adapting the sound and active noise cancellation to their unique shape. By calibrating the audio and noise cancellation precisely to the acoustic properties of each ear canal, your music arrives at your eardrum with its original balance intact, resulting in better audio and more powerful noise cancellation.
