4. Operating Instructions
4.1 Power On/Off
- Power On: The earbuds automatically power on when removed from the charging case.
- Power Off: Place the earbuds back into the charging case to automatically power them off and begin charging.
4.2 Active Noise Cancellation (ANC) and Transparency Mode
The EUQQ R210 earbuds feature both Active Noise Cancellation and Transparency Mode.
- Active Noise Cancellation (ANC): This mode reduces ambient noise, allowing you to focus on your audio. It is ideal for noisy environments like trains, offices, or gyms.
- Transparency Mode: This mode allows ambient sounds to pass through, enabling you to hear your surroundings and engage in conversations without removing the earbuds. The built-in microphones pick up external sounds and transmit them to your ears.
Refer to the touch control section (if available on the product) for specific instructions on switching between these modes.
