About the ear tips
When bass is difficult to hear and high range sound jars the ear, there is a possibility that the ear
tip fit is not appropriate. In order to enjoy music in accordance with the design of the earphone,
it is important that the ear tip fits properly and there is a means of sealing the ear canal. In order
to achieve the proper fit, please try the following method:
·
Please try various sizes, not just M size.
·
In case of small ears, please try not just S and SS size, conversely try larger sizes as well.
·
Even if the size of the ear canal is the same, the left and right ears may be different, so please
also try different sizes for left and right.
