Featuring breakthrough spatialized audio, world-class noise cancellation, and CustomTune technology that tailors sound and silence to you, our premium in-ear earbuds feel as good as they sound. Comfortable and secure, they come with nine potential combinations of eartips and stability bands to find your ideal fit. You’ll feel your music more with customizable listening modes, including Immersion Mode, plus enjoy simple touch controls and up to 6 hours of battery life. The ultra in-ear experience has arrived — sound just got real.

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.

Comfort and stability

The Bose Fit Kit features nine potential combinations of eartips and stability bands to help you find the ideal fit for each ear. Soft silicone umbrella-shaped eartips provide all-day comfort while the stability bands hug the contours of your ears snugly and securely.
