- Active Noise Cancellation (ANC) uses noise-cancelling speakers to reduce unwanted background noise. An ANC chipset inverts the soundwaves and a speaker inside the earphone cancels the outside sound by the neutralizing soundwaves.
- PAIRING INSTRUCTIONS: Press “. . .” to put into pairing mode (the indicator light will flash red and blue alternately). Go to Bluetooth settings on the device and find the Bluetooth pairing name “TR-BT941”. Pair the device and connect. Blue light flashes once the connection gets successful.
