Note: The actual invoice for calls and services from
your service provider may vary, depending on network
features, rounding off for billing, taxes, and so forth.
Noise cancellation
Noise from the surrounding environment is actively removed
from your speech using dual microphone noise cancellation
technology.
Noise picked up by a secondary microphone is removed from
the signal of the main microphone into which you speak. This

hold the device with the
main microphone
towards your mouth.
