Since the introduction of the Airman 750 headset, it has become the best-selling lightweight headset. The amplified noise canceling electret mic provides crystal clear voice transmission. A flexible boom allows you to adjust microphone to your preferred side, and an adjustable stainless steel headband make the Telex Airman 750 comfortable even on the longest flights. The standard Airman 750 is a two-ear headset. Shown here is the single-sided Airman 750. Both are TSO approved.
