Multi-Talker Noise Reduction System
“I hid it from myself just how severely I was cut off
from the world of normal conversation. Now I find the
Companion Mics system makes three or four-party
conversations anywhere outside the home an easier
and more enjoyable experience.”
R.W., MBA
“It worked wonderfully in a car with my wife and
another couple. For the first time in many years I
could understand and participate in conversation.”
M.R., Professor
“People I’ve asked to use Companion Mics
have been more than willing to do so.”
J.T., Assistive Technologies Consultant
“I have found that this system is
amazing once people try it.”
V.H., Au.D., Audiologist
“Today we went for a hike. Walking side-by-side and
when one of us was ahead by 30-40 feet, it was fine.”
M.P.E., Audiologist
“At a restaurant it was so noisy that it was hard to
hear myself talking. The results were startling.
Companion Mics can make a real difference in the
quality of life for a lot of people.”

How many talkers are needed for the system?
The Companion Mics system is flexible. It is the only
technology that connects the listener with more than one
talker. One, two or three talkers can connect with one
listener, depending on the size of the group. Unlike other
systems, Companion Mics includes
multiple talkers, while other devices
connect a single talker and listener
or a single talker with many listeners.
Can I use this product with hearing aids?
Companion Mics can be used with or without hearing aids.
The noise-isolating earphones that come with the system
are often preferred over hearing aids because they block
outside noise better than hearing aids. A neck loop
or silhouette can be used in conjunction with t-coils in
hearing aids. Companion Mics can also be used with
cochlear implants.

Our quality of
life depends on
our ability to
communicate with
family and friends,
but when it
becomes difficult
we often withdraw.
Why do I need this product?
It can be fatiguing and frustrating to carry on a
conversation in the presence of noise. Greater
concentration and effort are needed, and it is not
uncommon to withdraw rather than struggle to keep up.
Companion Mics make it possible to hear effortlessly in
difficult listening situations. The system is ideal when
dining in a lively restaurant, playing in a bridge tournament,
attending a lecture or
meeting, or riding in a car
with family and friends.
It can make the difference
between participating or
sitting out.
How do Companion Mics work?
A wireless link between each talker and the single listener
allows each talker to be heard as if the listener’s ear were
a few inches from the talker’s mouth. This system
dramatically reduces background noise and reverberation;
a noise-canceling microphone in each unit further reduces
noise. The 2.4 GHz wireless technology used in Companion
Mics is similar to that used by digital cordless phones and
Bluetooth™phones, so that more than one system can
operate in the same room without interference.
