Hi Dolf -

For me, is a simple "Plantronics" headset -
"Stick it in your ear" - selling maybe for US$ 50.oo...
Had that thing for my entire career, since 1969.
Weighs less than 50 grams, mike included.

No need to make my flight case any heavier to carry.
Besides, need room in there for my duty-free bottles.
And I do not like messing-up my hairdo.

Good luck with Cargolux - Excellent company.
Had a 6 months career with them flying their 200s in 1992.
