Description

The Bose QuietComfort Earbuds II set a new standard for in-ear headphones by offering an innovative combination of premium sound and market-leading noise cancellation. At the core of this technology is the groundbreaking CustomTune technology. This adapts both noise cancellation and audio performance to the individual shape of your ear canal in milliseconds, providing a unique and personalized listening experience.

Noise Cancellation and Sound Quality

The QC Earbuds II are widely recognized for their superior Active Noise Cancelling (ANC), which effectively filters out ambient noise like traffic or crowd chatter. In the Aware Mode (transparency mode), you can perceive your surroundings with impressive clarity. The integrated ActiveSense technology automatically dampens suddenly loud noises, such as passing buses, to a comfortable level without completely blocking out ambient sounds. For even more individual customization, you can adjust the equalizer (EQ) and create your own noise cancellation modes in the Bose Music App.

Design and Controls

Despite their compact design, the QuietComfort Earbuds II offer a high degree of fit and stability thanks to the included Bose Fit Kit. This kit contains three pairs of ear tips and three pairs of stability bands in different sizes, which can be combined as desired to ensure the perfect fit in every ear. The intuitive controls are managed via touch gestures on the outside of the earbuds, allowing you to control playback, volume, calls, and ANC modes.
