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.
