Using the Enhanced Features
The Sound Blaster EVO ZxR is specially designed to give you an amazing audio experience even while
you are in a noisy environment. Besides having advanced audio processing, the Active Noise
Cancellation feature further enhances your listening experience while TalkThrough gives you greater
convenience.
Amplify clarity with Active Noise Cancellation
Activate ANC to cancel out background noise for a cleaner audio experience! This is great especially on
flights, trains etc. where you can cancel out the constant rumbling noises.
Press the ANC button once to activate ANC, and press again to deactivate.
Engage Conversations with TalkThrough
When ANC is activated, turn on TalkThrough to have a conversation without taking off your headset!
This is handy for talking to flight attendants or to the people next to you while sparing you the hassle
of taking your headset off and putting it back on a moment later.
