The purpose of this page is to demonstrate the impact on the audio out of the Bluetooth with the vocal isolation function with the Lightspeed Zulu 4 ANR headset and compare it against competitive aviation ANR headsets. These recordings were created in a lab environment with the aircraft recording samples played at 95 db. The same voice actor was used to record the fictional tower communications, and a script was used for consistency.

Please listen to the various recordings from a Piper PS-30 Twin Comanche, a Cirrus SR20 and a Cessna 172, using the David Clark One-X, the Bose A30 and the Lightspeed Zulu 4 with the vocal isolation function enabled to hear the distinct clarity of each.
