supercool!
I have ordered mine from the local Bose dealer ( here in Italy.. ) they will be here within 3 weeks.... let's see .. I mean hear LOL!
I will let you know how I like it.
Right now on the 109S I'm using a set of David Cark fitted with the ANR kit from headsetinc.... I love them, confortable for my big head and quiet enaugh, but I have to say the overall audio quality and especially the microphone on the Aviation X ( the Grand come with those from the factory) are better.
Happy landings
