Product Overview

How to wear

Select & replace eartips
To get the optimal experience, we recommend that you give each of the different sized eartips a try and find the pair that fits your ears the best. The medium-sized eartips are pre-mounted onto the earphones. Please ensure that the eartips are firmly attached.
Flip the eartips over and mount them onto the earphones. Then adjust the whole to aim at the microphone hole.

Fitting adjustment
Insert the earphone into your ear and adjust to a position that you’re comfortable with. The better the fit, the better the noise isolation will be.
