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,
tap operations or Speak-to-Chat speech detection may not work correctly, or you may not obtain the correct sound
qualities, noise canceling effects, or call performance.
If any of this is the case, try the following.
After putting the headset unit into your ear, hold the side of the headset unit with your fingers and slowly push the
earbud tip into your ear canal.
Note
If you touch the touch sensor, the headset may operate.
Check if there is a gap between the earbud tip and your ear canal because the earbud tip is not inserted all the way
into your ear or the earbud tip is the wrong size.
Use the video function on your smartphone to check the fit on your ears.
The noise canceling effects may not be achieved depending on how the headset units are worn.
If you use the video function of your smartphone or other devices to record and check how the headset units are
worn in your ears, you can understand its feel when worn and get closer to discover the correct way to wear the
headset.

Wait for about 10 seconds for the earbud tip shape to stabilize.
If you feel your ears are not sealed, the noise canceling function is not sufficient or the low frequency sound
performance is not sufficient, try larger size earbud tips.
If the headset units come off while you are wearing them, try smaller size earbud tips.
