Sound shaped to you

Bose QuietComfort® Earbuds II are the next generation of wireless listening. Enjoy the best in sound and noise cancellation that is perfectly yours.

Everything tailored

You always get the best sound quality because CustomTune technology auto-adjusts it to your ears’ liking.

How it works:

• Your buds send out a chime to learn your ear canal’s unique shape
• The chime bounces back and gets picked up by the built-in microphones
• Your buds then optimize a noise cancellation and sound performance that fits you perfectly

Keep them in comfortably with soft eartips and stability bands that come in three sizes. Then, take the Fit Test in the Bose Music app to make sure it’s just right.

Tune in and tune out

Pure bliss is in Quiet Mode when you silence background noise with the world’s best noise cancellation.

When it’s time to pay attention, Aware Mode allows enough transparency to hear your surroundings or engage in friendly conversation.

The ActiveSense™ technology in Aware Mode can silence loud background noise to a stop, or soften it to a manageable volume.
