QuietComfort Ultra Earbuds are the ultimate wireless noise cancelling earbud experience.

It sounds so real it’s almost like you could reach out and touch it. Get real quiet when you want it and awareness when you need it. Or blend the two to your liking with these noise cancelling earbuds. CustomTune technology auto-adjusts the noise cancellation and sound performance to your ears’ liking. So everything hits just as it should.
