Simply natural
Effortless
enjoyment
Charm pairs sophisticated sound
processing technologies with
simple operations. So the natural
sound Sonic is known for is easy for
your patients to experience. Plus
Charm is easy for you to fit.
An emphasis on speech clarity
Speech Variable Processing
preserves the nuances of speech –
the soft and loud sounds that occur
in every word. These small details
enhance overall speech clarity and
create rich, full, natural sound.
No more whistle and squeal
The Adaptive Feedback Canceller
eliminates feedback before
it starts. Charm removes offending
signals – often before they are
even heard – for squeal-free,
easy listening.
Technologies to remove
unwanted noise
Charm uses multiple systems
to identify and reduce sounds
that could be noisy distractions.
• Directional systems reduce
unwanted noise so patients can
stay engaged in their surroundings.
• Speech Priority Noise Reduction
separates speech from
surrounding noise, making
conversations comfortable
and clear.
• Soft Noise Reduction reduces
the annoyance of low-level
sounds like the whir of a fan
or hum of a refrigerator.
• Wind Noise Reduction makes
time spent outdoors more
enjoyable by preventing wind
sounds from being amplified.
Programmed to please
Charm is not only easy for your
patients to use, it’s equally simple
for you to program with the
EXPRESSfit fitting software.
Pre-defined environments make
it simple to configure listening
programs for common situations.
• Data Logging makes it simple
to fine-tune Charm based on
actual wear data.
• EXPRESSfit includes support
for common fitting algorithms,
including NAL-NL2, DSL v5.0
m[i/o], and our exclusive Best Fit
Fast system.
Simple, natural, and easy-going. Charm has an

you. Charm has all the essentials your patients
need. Rich, natural sound. Noise-eliminating
technologies. Intuitive operation. Even wireless
connectivity. It’s the kind of solution you – and your
patients – will love. Pure and simple.
