How to enable or disable the
noise cancellation feature?
The earbuds have three noise control modes: Noise
cancellation, Transparency, and OFF modes.
You can switch between these three modes by pressing
and holding your left earbud for 3 seconds. You will hear a
prompt tone when the earbuds switch to a different mode.
The noise cancelling function
doesn't work well on my
earbuds.
• The noise cancelling function may be disabled. Enable the
noise cancelling function by pressing and holding your left
earbud for 3 seconds.
• The size of the ear tips is not suitable for you, or you may
be wearing the earbuds incorrectly. Choose the most
comfortable fit, and ensure your earbud makes a good seal
with your ear canal.
• If the sound openings such as microphone and speaker
openings are blocked by debris, then clean your earbuds
with a dry and soft cloth.
