Skype only
• Does not connect to any other devices
• Is focused solely on Skype (integrated
Skype button)
• Questionable performance even with other
PC applications. According to Polycom FAQ
on the Communicator: “Skype is the only
application that is officially supported by
Polycom Communicator model C100S. It is
optimized for use with Skype, and if used
with other Internet calling or voice
applications, Polycom Communicator may
experience diminished audio quality and/or
loss of button functionality.”
Audio Processing Built-in DSP - all audio processing
takes place on the Chat 50 itself,
utilizing ClearOne’s market-leading algorithms
for:
• Echo cancellation
• Noise cancellation
• Advanced input & output level management
• 20Hz-20kHz full bandwidth frequency
response for deep, rich sound
No on-board DSP processing -
code is loaded onto hard drive of connected PC:
• Audio processing tasks compete for CPU
resources with other PC applications such as
video conferencing over internet
• This could affect echo cancellation and duplex
performance
• No ability to ever connect to non-PC devices
because it contains no built-in processing

optimal positioning without need for
a stand

of laptops, enterprise phones,
cell phones, etc.
Moving part: design includes flip-out stand to
prop unit up:

Audio Quality Deep, rich sound with the best
full-duplex performance and echo
cancellation in the category PC
Magazine editor that gave the
Chat 50 the Editors’ Choice Award
stated that it has “excellent, full-bodied sound.
I found the audio comparable
to that of high-end Polycom
conference-room models which
cost far more.”
Early testing by other parties (not yet tested by
ClearOne) resulted in
significant echo and poor duplex
performance, particularly when
switching between headset mode
and speakerphone mode
