How Does It Work?
• The earSmart voice processor in your phone captures your voice and all the sounds around you.
• Working like the human ear, it processes and distinguishes these sounds, isolates your voice conversation, and removes background noise -
from both ends of a call.
• It also automatically equalizes and adjusts voice volume so you can hear and talk naturally, even in the noisiest places.
• With earSmart technology, you can talk where you want, and have clear conversations for mobile calls, video chats, even speakerphone calls,
without worrying about surrounding noise.
