13. What is the Active Noise Cancellation technology?
TREBLAB Z2 headphones are equipped with Active Noise Cancellation (ANC) technology. The headphones cancel background noise in your environment for an optimal acoustic experience. To turn the ANC function ON, move the ANC switch on the left earphone to the ON position. The LED indicator located next to the switch will turn RED. You can also use TREBLAB Z2 for noise-isolation without music playback by having ANC ON.
14. What type of Active Noise Cancellation is used in Z2 headphones?
Z2 is enabled with ANC function, of the "hybrid" type. That means the headphones are combining feedforward and feedback ANC by placing a microphone on the inside and outside of the ear cup. This type of ANC can suppress noise at a broader range of frequencies, adapt to and correct errors, and is not as sensitive to how the person wears the headset. ANC function is quite energy-consuming, and using this can increase the battery discharge. You can use the ANC function in both modes (BT and Line-in), for listening to music, or independently - as a noise-isolating function.
