Finally after 20 years of flying I bit the bullet and bought a set of BOSE A20’s with Bluetooth.

Wow. Why didn’t I do it sooner? The David clamps gave me a headache. The telex didn’t keep any noise out. Now I get quiet and with a little Tom Petty in the background. Nice break now to go flying and leave all that noise back at the terminal.
