The Telex line of lightweight headsets, both with and without ANR, is very popular—even dominant—in the relatively quiet cockpits of large corporate and commercial jets. Many new light jets are delivered with two Telex headsets as standard equipment.
Unfortunately, this leads many first-time jet pilots to believe the headsets are adequate for regular use in light jet cockpits. We have found this not to be the case. As the flight progresses and hearing fatigue sets in, it’s usually a matter of when, not if, pilots start missing radio calls if they’re using lightweight, on-the-ear headsets. The common fix is to get full-cup, over-the-ear headsets common in turboprops and pistons.
