"Used a mate's BOSE-X headset the other week in a quiet aeroplane (turbine)and thought it was crap!"
My company has within the past 2 years issued all crew with Bosse-X, we fly 4 and 2 engine, older type, turbo props. The noise reduction/comfort is really noticeable, after a long day, no more ringing ears at night
.
Donīt forget to adjust the settings on the headset volume control for the best effect. Iīm not going back to DCs.
