Issue Resolution
How do I pair my headset to a 
mobile device?
See Pair to mobile device on page 8.
Why don't I have NFC pairing on 
my headset?
NFC pairing is not offered on headsets built after 2021.
My audio unexpectedly switches 
between my headset and mobile 
phone.
● If you do not wear glasses, reset your headset sensors. 
See Reset sensors on page 12.
● If you wear glasses, try disabling the sensors. Your 
headset wearing sensors may not function correctly 
when wearing glasses with certain frame characteristics. 
See Disable sensors on page 12.
My audio is crackling. ● Your headset may be too far away from your connected 
device and out of Bluetooth range. Move closer to your 
connected device.
● Bluetooth density issues: If you are in a location with many 
Bluetooth devices operating at the same time (such as 
on a train or in a gym), they may be interfering with your 
Bluetooth connection and causing instability. Try using 
your headset in a less crowded location to see if the issue 
persists.
● Ensure that your headset microphone is pointed toward 
the corner of your mouth. See Fit on page 6.
● Callers can't hear me.
● I can't hear callers or music.
● Ensure headset is paired and connected to your phone. 
See Pair to mobile device on page 8.
● On iOS, check your audio output on your smartphone to 
make sure that the audio is directed to the headset and 
not another audio output.
● Your headset sensor may not be detecting your ear shape 
correctly. Reposition headset on your ear.
● Disable your sensors as they may be incompatible with 
your specific ear shape or glasses frames. See Disable 
sensors on page 12You may need to reset your sensors. 
See Reset sensors on page 12.

this setting may be incompatible with your phone.
