The HMEC 460 is a new circumaural pilot's headset with NoiseGard™ active noise compensation for use in propeller and turbo prop aircraft.

Its silver coloured surface gives it an exclusive and premium-class look. The HMEC 460 not only has an extra generously padded headband and extremely soft ear pads, it also features a low 8.0 N contact pressure, 20 % less than its predecessor.

The HMEC 460 even includes sockets for multimedia applications: an extra 3.5mm Audio-In-socket for those who want to connect their MP3-player directly to the headset, and a 2.5mm Cell-Phone-In-socket for the cell phone.
