The A20 aviation headset also provides a new level of comfort and stability. The overall headset profile is more compact, but the ear cup cavity has been enlarged to allow more room for the ears. These proprietary cushions improve the ear cups' acoustic seals, even over eye glasses, and remain comfortable during long flights. The solid magnesium headband is extremely durable, yet lightweight, and its sheepskin cushion eliminates hot spots. All these improvements have been achieved without increasing the headset's weight or clamping force. The A20 headset weighs just 12 ounces and exerts significantly less clamping force than most active headsets.
The redesigned control module now includes an auxiliary audio input with Intercom/AUX priority switching. Many pilots will want to use this input for dedicated GPS and traffic warning systems. You can set audio priority to mute the AUX input completely when intercom signal is detected, or to simply lower the AUX volume appropriately. Bluetooth® mobile phone connectivity allows you to receive calls wirelessly while wearing the A20 headset. And its enhanced EMI protection helps minimize interference from the mobile phone.
Smart power control
The power system in the A20 aviation headset includes a smart shutoff feature that helps provide at least 45 hours of use from just two AA alkaline batteries. With the installed version of the headset, the technology intelligently switches from aircraft power to battery power as needed.
Improved level of comfort achieved through choice of materials, distribution of weight throughout the headset, 1/3 less clamping force than most conventional noise reducing aviation headsets, and additional room for the ears.
