Hint
When you put the headset unit into your ear or adjust the positioning of the headset unit, see the illustration in step
for how to
hold the headset unit.
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 being worn properly in your
ears, tap operations 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.
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.
“INZONE Hub” will help you to determine which earbud tips suit you best to achieve the optimal noise canceling
effect, sound quality, etc.
Hint
The function that determines the optimal earbud tips for you measures the air-tightness of the earbud tips and determines
whether or not the headset units are being worn in your ears correctly. Select a size that fits comfortably.
When attaching and removing the headset
In the factory settings, the built-in IR sensors detect if the headset units are inserted or removed from your ears to control
the touch sensors and voice guidance.
When the headset is worn
You can use the touch sensors to play music, make and receive calls, etc.
You will hear a notification or voice guidance corresponding to the operation and status.
When the headset is removed
When the headset units are not worn for about 15 minutes after being removed from the charging case, the headset
turns off automatically to save battery. Turn the headset on by tapping the touch sensor or by putting the headset
units into your ears.
As a means of preventing the headset from reacting incorrectly, it is not possible to play back music, make or receive
calls, or perform other operations by tapping the touch sensors of the headset units when they are removed from
your ears.
Hint
You can also play music, make and receive calls, etc. when only one headset unit is worn in your ear.
You can use “INZONE Hub” to change the settings that automatically turn off the headset.
