It's the
Conversation
that matters
When talking on your mobile telephone with business
associates, partners, friends or loved ones at home, the most
important sounds are the sound of your voice and that of
the person with whom you are speaking. Everything else is
noise. Irritating noise that can easily disrupt the flow of your
conversation making it difficult for both of you to be heard
and understood.
This is especially annoying if you lead an active life and depend
on your mobile telephone to keep in touch. Whether you're out
in traffic, racing from meeting to meeting or carting across the
fairways of your local golf course, background noise should not
distract from what you say.
With the VMX 100, noise is no problem. It does everything you
want a Bluetooth headset to do, plus ensures that your voice will
be clearly understood – no matter how noisy your surroundings.
Background noise stays where it belongs. In the background.
You get crystal clear and hands free conversation.
VoiceMax™ dual microphone technology
VoiceMax™ dual microphone technology is the key to VMX 100
noise free mobile telephone conversation.
The genius of VoiceMax™ is a unique directional system using two
microphones and advanced digital processing to distinguish speech
from other noises. The two microphones work in synergy; one to
emphasize your voice, the other to remove noise.
What you say is transmitted clearly to the listener, while
distracting sounds such as wind, noise from traffic or machinery,
or the murmur of a crowd are effectively eliminated.
The VMX 100 is also easy on your ear. VoiceMax™ works in
tandem with an advanced noise management system. Incoming
signals are analyzed to isolate speech from noise. Only speech
comes through loud and clear.
The advanced features of the VMX 100 make it easier for
you to be heard, it also intelligently filters background
noises from incoming calls, enabling you to better hear what
is being said. Everybody benefits. That's reason to smile.
