For the proper sound quality, noise canceling function, and call sound quality to be effective
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, noise canceling effects, or call performance.
If any of this is the case, try the following.
- Change the earbud tips to ones that fit more snugly in your ears. When changing the earbud tips, try the earbud tip sizes in order from the larger ones to the smaller ones. The most suitable size of the earbud tips for left and right ears may be different.
-
See step
and check that you are wearing the headset properly in your ears. Wear the headset so that the earbud tip is comfortably situated as deep in the ear canal as possible.
Hint
- You can also play music, make and receive calls, etc. when only one headset unit is worn in your ear.
