Bose wireless earbuds QuietComfort Earbuds II, black

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:

1. Your buds send out a chime to learn your ear canal’s unique shape
2. The chime bounces back and gets picked up by the built-in microphones
3. 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.

You heard it correctly

Lifelike and well-balanced sound is our game, and we achieve it through innovative technology custom-built for small devices.

• No more “huh?” during calls thanks to built-in microphones that filter out ambient noise to focus your voice and deliver conversations clearly.
• Take personalization even further with Adjustable EQ settings in the Bose Music app. Control bass, mid-range, and treble levels as you go.

Life made easier

• Maintain energy all day with up to six hours of battery life in a single charge, and a charging case that holds three additional charges.
• Leave your phone where it is. Control music, answer calls, and adjust volume directly from the surface of your buds with Simple Touch.

Guided setup and controls in the Bose Music app keep your buds up to date. Manage Bluetooth® connections, sound preferences, and more.
