PortaPhone TD900DX Dual Ear w/ Switch The Porta Phone TD 900 HD Double Channel series set a new standard for high school, college and university coaching staffs that require an “Offense / Defense” talking pattern. These heavy-duty headsets feature rugged components and extra wide padding making them both durable and comfortable.


All TD 900 HD utilize a digital wireless technology known as Spread Spectrum Frequency Hopping. This special operating system “spreads” transmission across a section of the 900 MHz band instead of occupying just a single channel. The system is constantly monitoring the air and switches automatically to the best frequencies when necessary to avoid interference without any action required by the coaches.


The superior transmitting power provided by 900 MHz digital radio signals also set The TD 900 apart from any wireless on the market. This means that when faced with overcoming the many challenges associated with larger press boxes TD 900 wireless headsets will come through loud and clear.


This is an add on headset for an existing system.
