Commport Integrated Ear 
Microphone/Receiver System

This state-of-the-art Commport system contains a 
miniature microphone and receiver employing the 
latest sound wave and digital processing technology. 
Major benefits are superior sound quality and clarity 
as well as extreme comfort even for extended 
wear to hear and speak in high noise backgrounds. 
Available in different configurations (radio PTT 
adapter, ring PTT, palm PTT), the Commport 
system’s robust construction is suitable for fire in the

Hands-Free Accessories for 
Special Applications

The latest helmet-com is specially designed for users wearing any type 
of helmet (fire rescue, riot police, motorcycle, police troops) operating 
in harsh and hazardous conditions. Utilising a skull bone conduction 
microphone and effective speaker via a patented bracket system, it 
is connected to the 2-way radios via a large rugged fire retardant PTT 
that provides the electronic ”brain” to optimise the amplification and  
acoustic filtering of the bone conduction microphone. This low profile 
PTT also meets water (splash) proof (IP55) and intrinsically safe  
standards. 

 

 

 

 

 

The noise-com provides a cost effective, flexible, non-personal solution 
for users with existing hearing protectors/ear muffs operating in noisy 
environments. The noise-com unit easily fits to any hearing protector 
muff and can connect directly to the radio. Target markets are aviation, 
rail transport, heavy industry and manufacturing services.

Specially engineered for users with hearing loss or hearing impairment, 
this innovative temple-transducer headset converts receive sound 
signals to vibration pressure signals, which in turn is converted by the 
human brain as intelligible, listening messages. Since it no longer uses 
the human ear canal to receive sound, this headset is ideal for working 
environments that are subject to extreme high noise as well as for us-
ers who need to listen to external background. The “behind-the-neck” 
headset style makes it comfortable for extended wear and can be worn 
with hats or helmets.
