Bluetooth ear buds with noise cancelling: the CustomTune technology of the earbuds with active noise cancelling analyses your ears and adapts the sound to their unique shape.
Choose between nine soft ear inserts and stability bands to find the perfect fit for your Bose in-ear headphones – even during prolonged listening enjoyment.
Enjoy absolute concentration in quiet mode, detect your ambient noise in aware mode or activate immersion mode, which combines comprehensive noise cancelling with Bose Immersive Audio.
The Bose QuietComfort noise cancelling in-ear headphones provide up to 6 hours of listening enjoyment (up to 4 hours with immersive audio) and a 20-minute charge provides up to 2 hours of extra music enjoyment.
Answer calls or listen to your favourite music via both or a single earbud, just as you wish.
