How to communicate on tarmac runways at airports? With gestures or by removing the noise-canceling headphones... and as a result damaging your ears or breaching work safety? No need to as the APPI-Com throat microphone is compatible with noise cancelling earmuffs used by operators on the ground. No longer need to choose between permanent hearing damage and efficiency at work, just because you need to talk and hear your workmates!
Good penetration of the radio waves allows communication between the interior and exterior of the aircraft, the truck or the boat - natural dialogue, without button pressing!
