hi there.
just another vote in favour of the Sennheiser headset.i have a set without ANR (ANR was VERY expensive)and it has served me just fine,in fact i've used colleagues' Telex and Avcomm sets and they have nothing on this! its not heavy or big at all and it has a flip up function so you can keep just one ear covered,good for monitoring a frq in the cruise.
cheers! Cb
