Telex's next-generation Ascend ANR Headset provides a redesigned, more comfortable fit with high-quality sound. This versatile design was created for the cockpit but is easily reconfigured for personal use with the ability to change the connector, remove the boom, or add a battery. The advanced noise reduction (ANR) system coupled with limited speaker output and high-bandwidth frequency response provides the user with crystal-clear sound. A unique chassis equipped with pivoting ear cups provides a comfortable fit for the user and can be swiveled a full 180 for easy storage.
The Telex Ascend has been meticulously designed and rigorously tested to meet the FAA TSO standards necessary for use in commercial aircraft.
