Technical Standard Order. This means the Flex has been manufactured to a technical standard that allows this headset to meet the requirements of many air carrier (FAR 121,125, 135, and 91K) operating manuals. Most FAR 91 operations (General Aviation) do not require TSO headphones.
Designed for accurate reproduction of sound, the microphone and speakers will make every communication clear and easily understood.
This is a headset you can wear all day. The flexible microphone boom, stainless steel low profile headband, and speakers with their soft foam canal tips all result in only 1.5 oz. of head weight.
The noise reduction of the canal tips keeps your hearing safe from the harmful auditory environment of any aircraft. All Clarity Aloft Aviation Headsets have the same impressive full attenuation.
