Transparency Mode and Active Noise Cancellation (ANC)
The RCA Wave-78 earbuds offer both Transparency Mode and Active Noise Cancellation to adapt to your listening environment.
- Transparency Mode: Allows ambient sounds to blend with your audio, keeping you aware of your surroundings. This is ideal for urban environments or when interacting with others.
- Active Noise Cancellation (ANC): Reduces external noise, providing a more immersive listening experience. Smart ANC senses ambient sound levels and fine-tunes cancellation in real time.
To switch between modes, press and hold the touch control area on the left earbud for 2 seconds (specific gesture might vary, refer to quick start guide if provided).
