Earbuds

The earbuds feature a sleek, compact design. Each earbud is marked with 'L' for left and 'R' for right. The outer surface includes touch-sensitive controls for managing audio and calls.

3. Achieving the Best Fit

Proper fit is crucial for optimal sound quality and noise cancellation. The Bose Fit Kit includes three sizes of ear tips and three sizes of stability bands to ensure a secure and comfortable fit for your ears.

Selecting Your Fit

1. Experiment with different ear tip sizes (Small, Medium, Large) to find the one that creates a comfortable seal in your ear canal.
2. Choose the stability band size (1, 2, 3) that fits snugly into the ridge of your ear, providing stability without discomfort.
3. The earbuds come with one set of stability bands pre-installed.

Note: If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance. Change the earbud tips to ones that fit more snugly in your ear.
