In Ear Detection
When listening to audio with OPPO Enco W51 True Wireless
Headphones, removing either one of your earbuds will
pause the audio. Reinsert it to resume playback.
Noise Cancellation
OPPO Enco W51 True Wireless Headphones detect ambient
noise through the built-in microphones, and generate an
equal-but-opposite signal through the speakers to reduce
the ambient noise. Noise cancellation reduces unwanted
noise and offers you a clearer and more immersive
audio experience.
Notes:
• The noise cancellation effects may not be pronounced
in very quiet environments.
• The noise cancellation feature works better for low
frequency noise.
• The noise cancellation feature reduces noise but does
not completely cancel it out.
Restoring to Factory Settings
1.
Place your earbuds into the charging case and leave
the lid open.
2.
Press and hold the Function button for 15 seconds.
When the indicator blinks red three times, your earbuds
have been restored to factory settings.
