These days we’ve mostly moved beyond passive headsets in favor of ANR models for all but the quietest cabins-including jets and turboprops. But as a worthy alternative, ITE (in the ear) passive models can offer noise-canceling performance that’s on par with flagship circumaural ANR headsets, less the noggin-clamping pressure of even the lightest sets.
While an in-ear headset isn’t for everyone, among other in-ear models a favorite in our field reporting is the Clarity Aloft line from Aloft Technologies. Moreover, we have an early-gen Clarity Aloft in the flight bag and it’s proven itself such that in some cabins it’s the only set we’d reach for over the Bose A20.
