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
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.
